Lift Alarm

[Allen Higginson]

We are currently upgrading an old Android/Apollo system and there's a little quirk on it I need to check.The lift alarm is being monitored via an I/O on the fire alarm system and it brings up an alert of the FAP. I take it this is a no - no and should be part of a BMS set up as opposed to the fire panel?

Buzz ,
I don't see a problem with this , at least the cabling is monitored , which is better than some efforts on the lift alarms I have seen over the years.
I have just been asked to link in the standard disabled toilet alarms into a system , as security eventually found a lady in distress , and no one heard the standard alarm.
I have also monitored central battery units on emergency lighting systems for fault through the fire system , as it was monitored for fault at the receiving centre.
As far as I know the shutting down of plant via BMS is a no no , and should be hard wired .
The only thing that you might get pulled on is generating a red led on the panel , thats if you are going to do that  way , as you know all the other actions could be slow to register ie fault , and the lift button is probably non latching , so it could get messy.

Buzz, I see no problems doing this from a technical aspect if the 'alert' you mention is just an audible/visual warning that could not be considered a fire condition.

I know of nothing in the fire standards that preclude this sort of set-up as long as it has no detrimental effect on the functioning of the fire alarm system.

If the lift alarm generates a fire condition, then this is surely not appropriate and advisable.

You also don't say if the warning they get from the fire alarm system is the only warning of a lift alarm signal. If it is, there might be a problem. I don't know the lift alarm regulations but if there is such you might find that this set up doesn't meet that criteria.

If this set-up is in addition to a lift alarm signal meeting any appropriate recommendation, then I don't see any problem.

THanks for that - there is an alarm local to the lift but the lift can be remote out of normal working hours, o this is where the secondary alarm via the fie alarm comes into play.
