Eclipse BoostPak Leak Detection Option, V3, Installation Guide 630-LD 7/30/2010
Operation
Preliminary
This section supplements the operation section in your
Installation Guide 630.
Leak Detector Operation
When power is applied, the methane sensor will go to a
warmup mode for about 5 minutes.
The green LED indicates normal operation. The yellow
LED indicates a system failure. If this situation occurs, you
should contact the leak detector manufacturer for further
assistance. The detector has 2 sensors. A CO sensor
located in the module has no control panel function. The
remote sensor for methane operates relays in the control
panel. The four red LEDs indicate the gas concentration
reaches alarm level A and B for both sensors.
When the methane concentration reaches the first alarm
level (Alarm A), panel relay CR127 changes state. If the
gas concentration reaches the second alarm level (Alarm
B), panel relay CR128 changes state and the audible
alarm comes on.
Annunciation Control Panel Operation
On initial application of power from the building circuit
breaker panel, the yellow light on the Close Gas Valve
push button will come on. When the detector module
determines a safe condition, the green Safe to Enter light
comes on. Then the Open Gas Valve push button can be
pressed to allow gas supply to the equipment room. The
button must be held until its green light comes on.
If the gas concentration gets to the second alarm level,
then the gas valve will shut and the red Leak Detected
light and Alarm.
