Detector Base Series 200
B501/B501DG
Description
Specifi cations
The Detector Base B501/B501DG is designed to ac-
commodate intelligent fi re detectors Series 200 and
500 for use in ADM loops with System Sensor/200
protocol. Due to its robust multi-wire screw terminals,
the detectors can be wired with ease, thus achieving a
secure and durable connection.
The base provides the possibility to easily connect an
external remote indicator, and has been designed for
surface mounting in dry rooms. For special applicati-
ons a range of accessories (for moist room, false cei-
ling or fl ush installation) is available.
A mechanical theft protection of the detector can
optionally be activated at the detector base.
The Detector Base B501DG is 6mm higher than the
Detector Base B501, and is therefore suitable for thick
cables. It has the same height as the Isolator Detector
Base B524IEFT-1.
