Description

The Isolator Detector Base AISA-45681-321is designed to accommodate intelligent fire detectors Series XP95 and Discovery for use in ADM loops with Apollo/ Discovery protocol.

A dual-isolatorunit is integrated into the detector base, which reliably disconnects the loop in case of a short circuit. With the dual design, the input side or the output side isolator – depending on the location of the short circuit – interrupts the connection to the faulty loop segment. Therefore the detector remains in operation. A yellow status LED, which is integrated into the base, shows a steady light in case of a short circuit of the loop.

Due to its robust multi-wirescrew terminals, the detectors can be wired with ease, thus achieving a secure and durable connection. The base also provides a possibility for the easy connection of remote indicators.

The detector address is selected by means of a code card in the detector base. Therefore the detector can be changed without additional tools.

The base is designed for surface mounting in dry rooms. For special applications a range of accessories (for moist room, false ceiling or flush installation) is available.

A mechanical theft protection of the detector can optionally be activated at the detector base.
