System Sensor L-Series Selectable Output Chime CHRL, Wall Mount, Red
Sound the alarm, clearly and on code.
A wall-mount, red fire alarm chime with selectable tones and volume. It gives audible notification in commercial fire alarm systems and hospital-type quiet-alarm spaces.

A fire alarm is only as good as its signal.
Occupants need a clear audible warning, and installers need a device that goes in cleanly and tests out. The CHRL is built for both jobs in commercial fire alarm and mass notification systems.
Built for faster, cleaner installs
The L-Series design cuts install steps and keeps tone and volume settings simple.
Plug-in design
Plugs in with minimal intrusion into the back box.

Input voltage
Rated input for this indoor, wall-mount chime.
Continuity check built in
A mounting plate shorting spring checks wiring continuity before device installation.
Tone and volume control
A rotary switch sets the tone, with high and low volume settings.
Tamper-resistant build
Tamper-resistant construction and a captive mounting screw keep the device secure and the screw from getting lost.
