C-TEC, BF365IM, Conventional Sounder Isolator Module

C-TEC’s new BF365SC Conventional Sounder Controller and its associated BF365IM Isolator Modules are designed to interface to a fire alarm panel’s conventional sounder circuit. The Modules (each of which would typically have a conventional sounder connected to it) are wired in a loop arrangement, beginning and ending at the controller.

The Controller transforms the conventional sounder cir cuit’s monitoring and triggering voltages into its own unique control voltages which it uses to trigger the Isolator Modules and monitor the sounder loop wiring.

Each Module has smart sensing which means if a wiring fault should occur, the Module(s) nearest to the faulty section of cabling will, if needed, isolate this section. As the Modules are driven from each direction, any loss of cable integrity will have no effect on the functionality of the actual sounders.

Having a fault tolerant ar rangement such as this means that low cost cabling can be used for the sounder cir cuit (subject to the fir e officer’s approval), leading to significant savings in installation.

Specifications:

• Maximum of 35 modules per controller. 
• BSI Certified to EN54-17/18 when used in conjuction with the BF3655C
