Pilot gas alarms are powered
directly by 12V/24V battery
supply. They sense and give an
alarm for LPG, (butane or
propane gas) and carbon
monoxide (CO). The units are
not calibrated for diesel and
petrol fumes but these vapours
are detected at higher
concentrations. Pilot Gas
Alarms are important and
effective safety equipment and
are complimented by a gas
shut off valve in the Monitoring,
Multi-Gas and Controller
models.
