Addressable Relay Module


The TR-RELAY is an addressable relay module for use with the Triga Series fire alarm control panels (FACPs).


The TR-RELAY allows a Triga FACP to switch discrete contacts by code command. The relay contains two isolated sets of Form C contacts, which operate as a DPDT switch. No supervision is provided for the notification appliance circuit.


The TR-RELAY contacts can be used for virtually any normally open or normally closed application. Each TR-RELAY is programmed with a unique signaling line circuit (SLC) loop address. When an event occurs that controls the TR-RELAY, the relay is triggered by the FACP.


The TR-RELAY mounts directly into a 4” square electrical box. The box must have a minimum depth of 2-1/8”. A surface mount electrical box (TR-SMB500) is available from Triga.


The TR-RELAY is compatible with the following Triga Series FACPs:
• TR-2100R / ITR-2100B
• TR-2100ECSR / TR-2100ECSB
• TR-R2100R / TR-R2100B
