Hi There,
I look after a building (university library - small) that has a fire alarm system linked to deaf alerter system which signals pagers in the event of a fire alarm activation.
The occupants want to install a small PA system - with pagers for deaf persons.
I've never heard of this being done before.
Has anyone got any advice/information to offer?
Thanks

LOL You mean alert deaf people to a PA message they cannot hear, sounds logical.

You really need to discuss this issue with one of the companies that specialise in this area for their ideas and maybe costings.

It can be done - we installed a similar set up for a university recently. If the PA is "pre recorded" that can come up as text on a pager - if it's free speech - we used a speech to text convertor that comes up on display panels.

Over the top - yes, in terms of fire safety - it was just a response to an over zealous application of DDA

A couple of big red flashing fire signs would probably be more effective and cheaper. Alternatively a deaf loop (strangely most deaf people have hearing aids) and a notice would undoubtedly work very well, pagers for the deaf are a problem as they have to have then somewhere to feel the vibration alarm, particularly difficult for women who don't have shirt pockets. Then there is the loss rate, charging, making sure they work every day etc. which will be a killer for the staff. I wonder what "consultant (not OMS)" thought of this idea!

Of course I could do you a PA system which they could feel, probably no more expensive

Indeed - although you really only need to consider the scenario of the lone deaf person - ie where are they likely to be alone or isolated - so WC's etc, possibly stores or filing rooms. It's not credible that 60 people getting up tpo leave in a big office will be missed by a deaf person - management controls also normally include a "buddy system".

You do have to consider privacy though Dave - so you wouldn't want a wide ranging loop in many situations.

pagers for the deaf are a problem as they have to have then somewhere to feel the vibration alarm, particularly difficult for women who don't have shirt pockets. Then there is the loss rate, charging, making sure they work every day etc. which will be a killer for the staff.

maybe, I tend only to consider pagers where there is significant risk, sleeping acomodation or there genuinly needs to be an approach for "lone workers" - deaf or not.

LoL - it's just another tool in the armoury Dave - nothing wrong with pagers per se - as I suggested above, they can often end up specified in an over zealous approach by a client and risk transfer by the designer - it's akin to "safe refuge" alarms in two storey buildings - bit pointless, because you can usually talk to the next landing from the foot of the stairs
