Functions

Alarm Testing

Use the operating key to turn the switch to the TEST
position to activate a fire alarm. Turn the switch to
RESET to reset the detectors.

Sensitivity Testing

Connect a standard volt‑ohm meter (VOM) to the
voltage monitor plugs on the remote test kit to check
the detector’s sensitivity level after installation. The
voltage measurement decreases as the signal level
approaches alarm. This is caused by dust or dirt
buildup in the detector head smoke chamber. Refer to
the detector head's installation instructions for the
proper voltage levels.
