I was recently discussing how you know about fires and realised my reply thread could be a blogpost, so here you are.

I am deaf enough that without hearing aids, and while I'm asleep I won't hear a fire alarm, not even if it's really loud. I didn't have access to deaf-accessible fire alarms till I was nearly 30.

UK: Free fire alerting installations by fire or social services
In the UK often local fire services or social services will fit deaf-accessible fire alarm systems for free. In our case, the service was so unreliable and they kept not turning up (if there's a fire, the fire service will just not show up). So we bought our own.

I am not naming brands cos I don't want to get sued by some corporate whatevers.

Domestic deaf fire alerting systems in the 2000s and why ours sucked
In about 2009 we bought a system with wireless detector units and a bedside unit which has a flasher and a vibrator to go under the pillow. The units all get paired with one another on a kind of wireless network. The one we had was a standard domestic product that happened to have flasher/vibrate units. I found the LED on the bedside flasher unit which controlled the vibrator unit obnoxiously bright, so we had to put tape over it to dim it (like many deaf people I'm hypersensitive to bright or flickering lights or LEDs).

We didn't like this system though cos we found that if one of the detectors fell off its wireless network, the unit by the bed would chirp and the LED would change colour and flash... Not very deaf-alerty. It woke my partner but didn't give helpful information like WHICH of the 5+ units was not connected.

We also found the battery life of the detector units was poor. They claimed average of 5 years but we weren't getting 2 on multiple units. When a unit failed, the unit would chirp and then all the others would chirp afterwards so it was hard to know which was the failed-chirp and which was an echo-chirp. this always happened in the middle of the night (when it got cold and the failing battery's voltage dropped). These chirping units did not keep any persistent-alert, so unless you could locate the sound of the failing unit by sound, you couldn't work out which unit didn't work properly.

Again, not deaf-safe. This was waking my partner (and by extension me) repeatedly night after night, as partner would be running round the house trying to hear which unit was fail-chirping amongst all the echo-chirping.

Super stressful and beyond useless. After spending too much money replacing units with poor battery life repeatedly we stopped using the system.

Geeky partner did a fire alerting that most people couldn't do
I'm lucky, my partner is an electronics and computer programming person. She bought a higher end commercial fire panel unit for a larger building and detector and other parts for this system with WIRES to detectors which have strobes in them. My partner used the strobe/vibrator unit from the old system and did the computer programming to wire and program the commercial fire system into our very home-brew alerting system (fail safe, so it runs without mains for a bit or if the alerting system goes down).

While it's not up to commercial standards and it cost about 2-3x the usual domestic deaf-friendly systems (especially the panel), it's a lot less stressful and much more reliable. It links to stuff like using our alerting system to make all our house lights come on at full brightness and we have bright blue LEDs and LED strips so it's "FIRE". The commercial system detectors are about 30% cheaper per unit than the previous system. All the detectors also have a strobe and our main alerting system has separate strobes everywhere including the bedroom. The bedroom strobes only go off for fire, nothing else. If there's an issue with any of the units, the central panel will display exactly which unit it has an issue with and it stays there till someone actively re-freshes it. We can turn off our house-alert strobes if a strobe-sensitive friend visits (or plonk something over the strober).

Not everyone can do this level of research, affording the system, wiring and programming.

Deaf friends had a different rubbish deafie fire alerting system in the 2000s
When I was a student, deaf friends of mine had a different domestic "deaf friendly" system to the one we had (and it was nearly 10 years earlier). Their system did wake them up, but it also false-alarmed so much that even after getting repairs it kept false alarming.

Eventually after several nights of poor sleep, one of them smashed the detectors and they "did without".

Portable deaf alert systems
There are portable deaf-fire-alarms which pick up the fire alarm sound and will trigger a strobe and or vibrator unit. These are common in hotels or university halls.

I haven't had good experiences with them though. I had to try one at a former job, it didn't go off in two separate buildings unless it was within 1m of the sounder - which rendered it useless. I know people who have used the unit I had in halls and it was also hypersensitive, going off with the noise of their shower in a small ensuite student room, even with the bathroom door closed which caused other issues.

In hotels, if you ask for the deaf alerter, more than 50% of the time the reception staff don't know what you are talking about. Or if they do give you the unit, there's no instructions and often it has no batteries or flat batteries in it. The unit I'm thinking of used C or D type of batteries which aren't always that easy to find in a hurry, say late at night when you arrive at a hotel. I don't bother anymore cos I just can't face the hassle cos it's hassle and anxiety in advance "will they have one that I've booked", will they force me into a disabled room which doesn't have a bath (I need a bath) and will that cost me extra? And or hassle and anxiety trying to hear a stranger to get the unit and or batteries who probably can't help cos the corporate system stinks. I can Google instructions.

Crap systems are often worse than no system
Systems that don't alert to faults in a deaf-aware way are dangerous - not all deaf people share houses with hearing people.

False alarming is dangerous, it trains people to ignore the danger signs.

Systems that are unreliable and or do not last as long as they claim are dangerous. It's too hard to complain all the time. Easier just not to bother. Maybe the system my friends and I had are better now, I don't know, we don't use them.

Anywhere that uses the portable deaf alerters are legally obliged to train staff on their use and make sure they work reliably in the environments they are used in. I should encourage deaf people to assert our rights. I haven't stayed alone in a hotel alone for over 1800 days (thanks Covid!) so it's not been a battle I needed to pick...

Workplace fire alerting - can be a battle
Workplaces can often put a strobing unit in the same place a fire alarm sounder goes, OR they can easily wire in another unit for a deaf person.

Unfortunately in 2014 the law changed so that in an open plan space, if one unit has a strober, they ALL have to have a strober, which can cause access-clashes for people sensitive to strobers (even tho they should be able to use a non epilepsy triggering frequency). This can cause issues in open plan spaces. I don't understand this law and feel it is yet another case of not coproducing with deaf people properly and just assuming we'll tolerate badness or suffer bad solutions.

Many larger employers want deaf people to have a pager that vibrates. I will not use one of these systems (see below) cos as well as bad experiences, they individualise the fire alerting to the deaf person. They create a burden of deaf-person remembering to have the pager on them, the deaf person remembering to charge it, the deaf person ensuring it doesn't fall down the loo etc.

Workplace systems that rely on another person are very bad and should not be used as routine. I know several deaf people who had a "buddy" who was then not in or forgot on the day the alarm went off, everyone evacuated and the deaf person did not realise until later. That's a horrible and dangerous situation!

I don't know what the answer to open plan non-pager alerting is as I haven't yet had to deal with it. I anticipate "unfun" cos I won't use a pager and employers will want me to use a pager.

Some of my experiences of workplace fire alerting
In one job where there were open plan with 200+ people on each floor, there was a brilliantly comprehensive fire system which worked really well - it was for anyone who couldn't evac typically, not just disabled but was significantly pregnant, injured etc. All by self-declaration. You were encouraged to self-declare for known reasons in advance and got shown round. The system was SO good a non disabled colleague who hurt his leg the day before, just used the refuge system cos he knew it was there was there was zero stigma and positive encouragement to use it.

Another job it took the employer over 5 years from disclosure to installing a working system. I had to give permission to ManagerTwit to share my deafness with 4 people but ManagerTwit who told those 4 people, told them "Natalya will contact you". When I arrived, I asked about fire alerting and no one knew who the 4 people were. ManagerTwit worked in a different building, everyone was scared of, or disliked them. I was given a fire-safety tour by EstatesTwit alongside 2 new starter colleagues, but I couldn't understand EstatesTwit's accent, he wouldn't speak up or slow down and we were walked at high speed round this unfamiliar building. I asked about the alarm sound and was told "It's really loud, you'll be fine". I explained how deaf I am and got told "the alarms are 60dB it's fine". I explained again I can't hear 60dB at any frequency without my hearing aid. I asked for a bell-test and this was just ignored and refused a lot.

I kept asking but the bad manager, HR and Estates all buckpassed and I was bullied repeatedly by HR for "not sorting it out" even when I showed proof of following their instructions to ask Estates. I got a nicer manager and they tried but they and their manager also got stonewalled and gaslighted at every turn.

The first time I heard the alarm, I thought it was Yet Another Pneumatic Drill outside the building. I only realised it was the fire alarm cos the colleague I happened to be talking to white with fear. We evacuated. The bell sound was actually better for most deafies as it was a lower frequency sound like a bell, not higher frequency like sirens tend to be. More deaf people have better lower than higher frequencies (especially cos age related deafness is usually higher frequencies first).

We had 3 actual fires in the building over the next few years, a few toast/oven burning incidents in the kitchen and then a faulty heater in someone's office. After the last incident I made a last ditch attempt to get something. The only option was to try a portable system, which didn't work...

I got really fed up and my nice local managers were equally flummoxed. So I wrote a threatening legal letter (effectively a Letter Before Action) to the director of Estates asking for an alarm within a month or I'd sue, tell the Health and Safety Executive and the local fire service. This threat letter worked well, I got prompt director of estates responses, apologies, requests for information to see where things had gone wrong and two men measuring up within 2 days. The flashing unit with sound was installed within 2 weeks and did work.

The installer guy was lovely, he let me listen to all the sound options to choose the best one. I later found out they got it through so quickly cos unlike every other purchase which requires purchase order number requests, layers of approvals and then whatevers, the Director told the frontline installers "Get It Done, paperwork later" and they had a flashing sounder ON THE SHELF...

Pagers and why I hate them
In another office, I couldn't have a wired in strober cos it was open plan and the law doesn't allow just 1 strober. I got told to have a vibrating pager... I went to collect a pager from the building reception. No battery in it. Awful confusing instructions. I happened to have batteries so I sorted that.

The pager went off with every single fire-alarm test in every single building across my employer's estate which had 30+ buildings. This involved vibrating alerts every morning for 2 hours at least. I left the pager on my desk when going to a half-day meeting, it buzzed and buzzed and buzzed. My colleagues eventually yoinked the battery.

Sources of deaf alertery things
I highly rate Connevans for deaf gadgets of all kinds including deaf friendly fire alerting. It looks like RNID wound down their shop and direct people to Connevans. https://www.connevans.co.uk/catalogue/11/Deaf-Equipment

If you are in employment, ask your estates department and if they don't help quickly, then try HR. If that doesn't work, write a complaint to the "Director of Estates" explaining your issue politely and asking for a fix within 4 weeks or you will complain to the Health and Safety Executive (HSE), Fire Service and raise a disability discrimination grievance. I have helped several people do this, especially after they've been forgotten during evacuations and it has worked every time.

Blogging Against Disablism Day 2016

I want to talk about disabled-gain.

Over the last 8 years I have had the privilege of working closely with two different colleagues who access computers in a slightly different way from the majority of people. They are screenreader users which means the computer tells them in voiced words what is going on. Instead of pointing and clicking at visual things with a mouse, screenreader users usually use the keyboard, by learning and utilising many shortcuts.

In 2009 I experienced difficulties with my main mouse-hand which means I have to be careful about how much mousing I do. I had always been a fan of keyboard shortcuts and used them as much as possible when I could find them out from getting my first graphical computer in 1993 (Mac OS System 7.1.1 for the nerds out there). I knew that once my mousing became limited I had the option of copying one of my colleagues to increase my use of keyboard shortcuts.

I learned a few new shortcuts each day and would ask my colleague what the shortcuts were for tasks I did regularly. My favourite trick is to build complex tables in word documents entirely by keyboard - that always gets a wow out of anyone watching me do it. I am now doing about 80-90% of my navigation of Windows by keyboard and continually working to get it to 100%.

I am not just mitigating the impact of a functional impairment, but have become empowered to work more efficiently and speedily as a result. Disability gain!

Many big tech companies are catching on and building accessibility into their core product realising that disability is not rare or special, but is common, normal and accessibility features can empower users.

  • We still have a long way to go, many products and cloud-based applications are not keyboard navigable which means that they disable me and I am unable to use them. I have learned I am not the problem, they are.

    Connevans fmGenie


    In 2007 after not having used radio aids since primary school I got a Connevans fmGenie radio aid system with the transmitter and a receiver which I connected to my Bone Anchored Hearing Aid (BAHA) via a Direct Audio Input lead.



    BAHA upgrade


    In 2011 I upgraded my analogue BAHA Classic + digital BAHA Divino to a pair of BAHA Intensos from Cochlear which are both digital (but not really programmable).

    I continued to use my fmGenie but struggled with increased radio interference hissing problems which could only be reduced by waving the transmitter box around to the least hissy place. I tried multiple units and all were equally poor. I can only conclude I'm hearing the hiss I couldn't before or there are more sources of radio interference around.

    Comfort Digisystem - digital radio aid


    In April 2013 I attended an assistive technology seminar and I got a chance to talk with Gordon Morris himself who demonstrated the Comfort Digisystem to me because I had a direct audio lead with me.

    The digisystem is very modular with a variety of different units.

    I have:
  • Transmitter Microphone DM10 which can clip onto the lapel of a speaker.
  • Conference Microphone DC20 which can be used as a transmitter and receiver.
  • Receiver DH10 which I use to connect my BAHA to the system via Direct Audio leads.


    Initial impressions


    My partner is very geeky so I let her loose with the manual and the digisystem bits figuring I could let her do the difficult bits. We then spent the afternoon playing with the different modes.

    One advantage of some of the advanced digisystem modules is that they can all connect through one another. In my case this means that as well as the DC20 conference mic and DM10 lapel mic each pairing with the DH10 receiver that the DM10 mic can connect through the DC conference mic. This is useful for hearing a single speaker AND a more local group and mute each source independently.

    This pairing process is possibly quite tricky, I still need to get my head around that so I can redo it if needed.

    The DC20 conference mic can also act as a receiver unit cutting out the need for the receiver unit in some situations. This is definitely useful for me and I had used the fmGenie in similar ways. The 3.5mm jack on this can be used for line in, headphones in and microphone in and has a menu option for changing the mode and how loud each one is.

    The DM10 lapel mic has no menus or interface other than on/off and pairing. The menus on the DH10 receiver and DC20 conference mic are very straight forward and use words which is great, I detest menus which use pictures as I can't remember which is which. The multi-directional switch is flicked up/down to move and pressed centrally to click as it were which takes a bit of getting used to.

    Gordon had shown me the Equaliser on the DC20 conference mic when he demoed it which I really liked. The BAHA isn't great below 250Hz and my worst hearing frequencies are below about 800Hz. I have initially set mine to drop everything 500Hz and below to as low as it'll go, a peak at 1kHz and then levelling out at the higher frequencies. The sound is artificial but is useful for prioritising certain sounds.

    There is also some background noise processing going on as I found some modes would cut out the computer noise from the room after a few seconds, especially if I switched between directional mic and omni mic mode on the DC20. Mode switching is easy with a remote control with options, or buttons on the side of the DC20.

    We did experiment with the external lavallier mic added to the DM10 lapel mic and it worked just fine but I didn't think it was something I would rely on very often as it's yet more bits.

    What next?


    I hope to start using it at work in meetings and training sessions to get a better idea of how it works in practice.
