Two Wire Fire Alarm System

Two Wire Fire Alarm System

A two wire fire alarm systems is like a conventional system, in that it identifies activations as zones and not as a specific device.

The big difference however is that two wire fire alarm systems cable detectors and sounders on the same pair of wires.

This can save on both cabling and installation time and reduce the overall cost.

This wiring format can help when upgrading and adding to an existing conventional system, allowing existing cables to be used for new detection and sounder circuits.
C-TEC’s two wire control-panels are compatible with Apollo’s ‘Alarm Sense’ range of two-wire detectors and sounders.

Where there may be a requirement for strobes to be built-in to a detector base and have the ability to incorporate programmable time-delays then Fike’s ‘Twinflex’ range can provide even more functionality than a basic two-wire system. Whether new or upgrading we have the right solution for your business and your budget.
