Schematic diagram showing how to land the wires when using an auxiliary.
Fire alarm door release relay.
It ensures that in the event of a fire or a fault on the fire alarm system any doors that are.
System sensor multi voltage conventional relays are used for high current switching applications such as fan and damper assembly control door control air handling unit controls and other types of building system interfacing.
Integrating fire alarm control using direct wiring.

We can use a relay to drop power to the electric lock or use an ip device that drops power using the network connection or add a power control box that drops power when the fire.
Consult the list to find a relay for your specific fire alarm or notification system.
The door access control reader and the electric lock can be wired to the fire alarm in a number of different ways.
To prevent transient voltage spikes from burning out the control relay contacts an auxiliary relay with big contacts should be installed between the fire alarm control relay and the door holders.
These contacts can be used to control external appliances such as dampers fans door holders etc.
A range of easy relay fire alarm relays are available from 12v and 24v dc coils to 230v ac 50 60hz coils.
Relay module 55 043 provides two sets of form c dry relay contacts that switch together one dpdt relay.
The door release module is an interface designed to enable eaton s addressable fire alarm systems to work in tandem with door holders retainers.
The intelligent fire alarm relay can only be used on intelligent fire alarm systems and is made specifically to work with particular brands of fire alarm systems.
Our newest addition to our fire alarm relays category is wireless fire alarm relay that allows a network of wireless relays with 4 inputs outputs to be connected.
The normally open contact of the remote relay which will be held closed in normal state should then be wired in series with the door mag supply and not the rte button this way it is fail safe in that if the cable from the fire alarm panel to the relay gets damaged the relay will open and the door mag release.
Then the auxiliary relay takes the voltage spike and the fire alarm control relay only has to turn off the auxiliary relay.
Developed to be compliant with the bs 7273 4 2015 code of practice for the fail safe operation of door release mechanisms and door holders.
The module is compatible with fike s cyber cat and cheetah xi intelligent control panels.
