Control Panel Compatibility
AMS220/220T Smoke Detectors are addressable system detectors
that are
only
for use with DSC fire and security control panels
equipped with the compatible interface. The AMS220/220T Smoke
Detectors
cannot
be used with a standard 2-wire smoke detector
interface. Any standard 2-wire smoke detector, including the DSC
MN220 series, will
not
operate on an addressable circuit. The
AMS220/220T series and the MN220 series are
not
compatible,
interchangeable or substitutable.
The addressable interfaces have a proprietary power and signaling
system. Voltage ratings are not indicative of compatibility. The
current rating is provided for circuit loading calculations only.
Please refer to the control panel information for details on the
installation of addressable circuits.
AMS220/220T detectors are compatible with the following control
units:
PC4010/4020 v3.0
Introduction
The DSC AMS-220/220T Smoke Detectors are smoke detectors
intended for open area protection. They are suited for commercial,
institutional and residential fire alarm systems.
The DSC AMS-220/220T Photoelectric Smoke Detector incorporates
many advanced design features to provide years of reliable
operation. It is important to follow the installation and operation
instructions on this sheet to ensure that the unit will function properly
— even the best designed smoke detector will be rendered useless
if it is not connected or located properly.
It is very important that you understand how to test and maintain your
system. Refer to the instruction manual for your alarm system, and
familiarise yourself with how the fire alarm functions of your system
operate. Be sure to test your system regularly following the test
procedures described in your manual. If you should ever have
problems operating or testing your system, and especially if there
are problems with the fire alarm functions, contact your smoke
detector installer or dealer immediately for service.
While smoke detectors and alarm systems are designed to warn you
of potentially dangerous situations, no system can prevent
emergencies. An alarm system is not a substitute for life and
property insurance; you should always maintain appropriate
insurance coverage.
