1. GENERAL DESCRIPTION
The STCP-1000 series gas detector provides an early warning of the presence of
explosive propane gas and is factory calibrated to sound an alarm that meets UL1484
standard. The L.E.L. (Lower Explosive Level) of propane gas is 2.1% in volume and
the alarm level of this detector is set at 10 – 25% of the L.E.L. (Lower Explosive
Level).
When the alarm is triggered the red light and buzzer will stay on for a minimum of 5
minutes. If propane gas levels persist beyond the calibrated level, the detector will
continue to alarm until the propane gas is cleared. See OPERATION section for
further information.
There have been many cases of serious injuries and damages reported that were
caused by propane gas leak explosions.
IMPORTANT!
READ ALL OPERATION INSTRUCTIONS CAREFULLY.
FAMILIARIZE YOUR FAMILY WITH THE ALARM SIGNAL AND WHAT TO DO IN
THE EVENT OF AN ALARM.

3. RECOMMENDED LOCATIONS OF DETECTORS:
•
Install at least one propane gas detector on every floor level (see figure 1).
•
Install the detector close to every place that gas operated appliances are installed
(see figure 1).
•
Since propane gas is heavier than air (1:1.6), the greatest concentration of gas will
be near the floor. Mount detectors on the lower wall 2 feet from the floor, and at
least 2 feet (61 cm) away from any corner of the wall (see figure 2).
