The Apollo AlarmSense 2-Wire Relay Module (55000-835APO) acts as a vital interface between an AlarmSense fire system and external building equipment. This module allows the fire alarm to trigger auxiliary safety measures-such as releasing door magnets or shutting down ventilation units-the moment a fire is detected on the 2-wire zone.Auxiliary Control: Provides a volt-free relay contact to switch external circuits, including door retainers, smoke vents, and elevator overrides.Loop Powered: Draws its power directly from the AlarmSense zone, removing the need for an external power supply and simplifying the wiring architecture.Standard Mounting: Designed to fit onto a standard fire-rated backbox or within a specialized enclosure for a clean, professional installation.Zone Triggered: Automatically activates in response to an alarm signal from any detector or manual call point on the same AlarmSense circuit.This relay module is an essential component for commercial fire safety strategies that require automated system interlocks. It is widely used in blocks of flats, office buildings, and retail environments to ensure that life-safety functions, like fire door closing, occur instantly and reliably during an emergency.Explore the full Alarmsense range for compatible products and accessories.Why buy from Direct Trade Supplies?Competitive trade pricing, fast UK delivery, and trusted products from leading brands.
