A useful isolating device that allows a +24V d.c. output from a fire panel to be temporarily cut-off to prevent external equipment (such as autodiallers, roller shutter doors, etc) from operating. Incorporating an isolating key switch and amber LED, the unit helps safeguard against the inadvertent triggering of auxiliary equipment during routine maintenance. If the output controlled is monitored, a fault condition will show at the host panel when the key switch is ‘ISOLATED’. Mounts on 25mm UK single gang back boxes.
