4-way relay unit

The 4-Way Relay Unit enables third party systems (e.g HVAC, security, access control etc.) connected to the fire alarm panel to be isolated so that repairs and maintenance can be completed without compromising the integrity of the overall installation. Volt-free contacts mean voltages are kept completely separate, increasing overall system safety.

It features four pairs of up to 125VDC at 5AMPs or 250AC at 10AMPs rated relay contacts, housed in a robust sheet steel enclosure that can be operated using switch negative signals from up to four control panels. Isolated switches and status LEDs are provided for each relay.
