4-output supervised relay module for DSC PowerSeries Neo — drives external sirens, strobes, door locks, BMS contacts, and integration relays from the panel’s programmable output (PGM) logic.
Deployment context
Cross-system integration: panel triggering door maglock release on fire alarm, exterior siren control, BMS contact closure on alarm event, parking-light activation on after-hours arming. Required where panel’s onboard PGM count is insufficient.
Zones, inputs & wiring architecture
Not applicable.
Communicator & monitoring compatibility
Not applicable.
False alarm & reliability positioning
Per-output supervision — installer detects open/short/missing wiring without needing to test each output. Failed-output reporting back to the central station and the keypad event log.
UL / commercial compliance
UL1610, ULC-S304. Listed for control output integration in burglary and access systems.
Commonly paired hardware
DSC PowerSeries Neo panel · Securitron M62 maglocks (release on fire alarm integration) · exterior sirens and strobes · BMS contact-closure inputs · Altronix RBSNTTL multi-voltage relay (for higher-current loads)
