Operation

When first turning the unit on, the S-2A goes through an audio/visual cycle of all indicators and the audible horn. Beginning with sensor #1, the indicators will cycle green, amber, and red. This will then continue with sensor #2. If optional sensor #2 is not installed the indicator light will turn off. The unit fault indicator will then illuminate, and then the horn will beep.

The sensor lights may flash green during the warm-up period. This flashing will occur only if a sensor is connected. Warm-up time will vary depending upon usage of the unit. Long periods of inactivity will require long warm-up periods. After the warm-up period, the indicator will change to green. It a sensor is not installed the sensor indicator will turn off. The solenoid control may be tested by pressing the solenoid switch. Pressing this switch again will turn the solenoid off.

CAUTION: Be certain solenoid switch is on! Gas will not flow through the system.

Should either of the sensors detect propane or CNG fumes, the corresponding indicator #1 or #2 will change to red and the audible horn will sound. The indicator will remain red as long as fumes are detected. The solenoid control will turn off. Do NOT consider the area clear until the indicator light returns to green.

Testing Display Mode

Internal operation of the display mode may be tested using the corresponding TEST switch. Pressing the test buttons will simulate the above alarm conditions.
