Description

The Isolator Detector Base B524IEFT-1 is designed to accommodate intelligent fi re detectors Series 200 and 500 for use in ADM loops with System Sensor/200 protocol.

A dual-isolator unit 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 out- put side isolator – depending on the location of the short circuit – interrupts the connection to the faulty loop segment. Therefore the detector remains in ope- ration.

Due to its robust multi-wire screw terminals, the detec- tors can be wired with ease, thus achieving a secure and durable connection. The base also provides a pos- sibility for the easy connection of remote indicators.

The base is designed for surface mounting in dry rooms. For special applications a range of accesso- ries (for moist room, false ceiling or fl ush installation) is available.

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