Battery Back-up: If
a power outage should occur during ammonia concentration monitoring,
an optional Battery Back-up can be added to the LBW-50 or LBW-420 Ammonia
Leak Detectors.
The Back-up Battery is on a constant charge during normal operation.
When
power goes out, there are approximately 11/2 hours of continuous
back-up power to the leak detector for monitoring. The standard Battery
Back-up comes with a battery, mounting
Velcro, and a wiring harness with black & red leads.
Remote Alarm Light & Horn
Unit: To accommodate an already excellent line of ammonia
leak detectors, the optional Remote Alarm Light & Horn Unit allows
for a remote indication (red blinking light and piercing horn) of an Alarm
condition. The Remote Alarm Light & Horn
Unit can be silenced
with the Silence/Normal/Test toggle switch but the red light will continue
to blink. If you happen to forget to turn the unit switch back into the
Normal mode, the horn will alarm again when the ammonia concentration has
diminished below the leak detector
Alarm setpoint. This unit is available for the LBW-50 or LBW-420 Ammonia
Leak Detectors and comes standard with a NEMA 4X box, red light, horn,
silence/normal/test toggle switch, and 50 feet of cable.
