ZFP 4 Way Relay PCB (half size)

4-Way Relay PCB designed to enhance the functionality of a ZFP addressable fire panel to include 4 additional relay outputs.
4 x 1A 30V single pole contacts.
Programmable via the ZFP’s PC Tools.
Polling, power and separate Relay Activated LED indicators.
Up to 15 A-BUS Expansion PCBs can be connected to a ZFP Panel via its RS485 A-BUS network.
Typically installed within the ZFP panel but can work up to 1 KM away for non-EN 54-2 functions.
