C-Tec BF366 Isolatable Relay on a Plate 24v 5A

The BF366 is a double-pole 24V 5A polarised relay specifically designed for use in 24V fire alarm systems. It includes a key switch isolation facility allowing the relay operation to be temporarily disabled from the fire alarm signal during routine test and maintenance (to prevent auto diallers, water sprinklers, roller shutters, etc., from activating).

Mountable on a 25mm flush or surface mount back box, the relay is trigger able via a control panel’s open collector output or a standard polarised fire alarm sounder circuit. If connecting to a sounder circuit, note that the relay will return to its normal state when the fire condition is cleared or silenced. Check with the approving authority that the proposed arrangement is acceptable prior to installation.
