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 4 box, red light, horn, silence/normal/test
toggle switch, and 50 feet of cable.
