The relay must be dioded for polarisation and suppression as shown. These
diodes should be marked 1N1004 or similar, and may already be located on
the relay PCB if it is designed for Fire Alarm Systems. If the relay is a
general purpose plug in relay then the diodes may need to be added
externally.
