Isolator Detector Base
B524IEFT-1
Description
Specifi cations
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.
