life and low maintenance detection of many gases and solvents. The instrument is
powered by either 115 VAC or 24 VDC, (48 VDC version also available). It consists of
a plastic enclosure with flanges provided for wall mounting. Holes are provided on
the base of the housing for wiring entry, and the unit is supplied with the gas sensor
located on the end of a 30 foot cable. The PS-2 has two alarm levels, calibrated to the

alarming device or activate some other device such as a ventilation fan. The front of
