Overview

Reliable gas detection sensors answer the safety requirements of increasingly stringent building codes for today's industrial and commercial environments.

Gases to be sensed in HVAC applications include: carbon dioxide, carbon monoxide, nitrogen dioxide, methane, oxygen, ozone, CFC's/HCFC's/HFC's, chlorine, ammonia and others. These can all be monitored specifically to give gas leak indication in the ppm range without false trips.

Manning Systems can supply a single point system, four-channel system, or multi-channel units that monitor as many as ten sensor points at a single master control panel. All readouts have relay outputs to notify security personnel or activate fans, etc. Sensors give a 4/20 mA output and can tie directly to a building control panel. For ventilation requirements our most economical gas sensing system is the new linear solid-state / relay plug combination. It can be configured for R-22, carbon monoxide or hydrogen sensing.
