Fire Alarm

[Mathuna]

Can an conventional fire alarm system be used in conjunction with a elevator. Or does it need to be an addressable system.

In what respect fitting automatic detection in the lift car or lift shaft. If in the lift car I don't see why not but I would connect it to its own zone but you may have issues with its connection. It is a requirement of BS5839:1 to have a zone plan at the control panel.

Thanks. Theres a new lift been fitted and the lift company are looking for a io at top of shaft beside power supply. Have not asked them yet but I presume its to stop the lift in case of fire. Just checking as the fire alarm is a conventional type.

You can fit one in the shaft connected from a conventional system. Normally a suitably identified remote indicator is fitted to give notification it has been activated. It will not stop the lift however some complex sysyems can default the lift to a safe level.

Check the manufacturer. I'd say take an Gp from the panel to the lift. Usually have a few relays in there

Are you not sure that they are asking for a relay with com, NO/NC relay

I think they are asking for nothing more than automatic detection in the lift shaft.

Cant beat a good piece of guess work on something as safety critical as a fire alarm.

Sounds like they are asking for a relay output from the fire alarm, if that is the case the question needs to be asked what cause and effect this will give as driving the lift to a specific floor may actually take people in the lift into the fire.
Heard of something similar a while ago this site had an addressable panel so there was a work around, the lift default in case of a fire alarm was to be the ground floor somebody then came up with the what if the fire is outside the lift on the ground floor, the setup was then changed if the fire detection indicated a fire in the location of the lift exit on the ground floor then the lift was programmed to stop at another floor
I think the fire risk assessment (assuming you do these in Ireland) needs reviewing before this goes any further and the function of I/O needs to be understood

Without further information I am only assuming this is what they require.
