C-TEC Auxiliary Device Isolator (BF367)

The BF367 allows a +24V d.c. output from a fire alarm control panel to be remotely isolated to prevent external equipment (such as autodiallers, rollershutter doors, etc) from operating. This is a particularly useful function during routine test and maintenance as it safeguards against the inadvertent and potentially hazardous triggering of auxiliary equipment.

To aid location, the BF367’s front label has a white ‘write on’ panel allowing installers to add their own personalised text such as equipment locations. The unit will fit on 25mm deep flush or surface mount back boxes.

Features

The BF367 incorporates an isolating keyswitch and a high intensity amber LED. The switch circuit has been designed so that if monitoring is used on the +24V d.c. output being controlled, a fault condition will show at the fire panel when the BF367’s keyswitch is in the ‘ISOLATED’ position (note that the key can be removed from the keyswitch in both the ‘ON’ and ‘ISOLATED’ positions).

The unit’s amber LED can also be set-up to illuminate when the keyswitch is in the ‘ISOLATED’ position provided sufficient voltage is present
