Description

The Zone Monitor with Isolator is supplied with a backbox for surface mounting, and is for indoor use only. Two LEDs, one red and one yellow, are visible through the front cover of the enclosure. The red LED is illuminated to indicate that a fire alarm condition has been detected on the zone wiring. The yellow LED is illuminated whenever the built-in isolator has sensed a short circuit loop fault. The backbox is a polycarbonate moulding.

Key Features:

• fitted with a bi-directional short circuit isolator
• unaffected by loop short circuits
