Critical Environment Technologies Controllers

Self-contained and multi channel system controllers that can handle up to 128 channels.

Critical Environment Technologies offers a self-contained controller with up to 3 gas channels configurable with internal and/or remote sensors. A self-contained controller is ideal for small applications where only a couple gas sensors are needed. The self-contained controller can be powered by line voltage (90-240 VAC) or low voltage (24 VAC/VDC) and offers Modbus® RTU RS-485 or BACnet® MS/TP RS-485 output signal for communicating with a Building Automation System.

Our feature rich, multichannel controller offers sophisticated logic for priorities and zoning and works with any of our gas detectors to provide small application 4 channel systems up to robust 128 channel systems. The controller is usually located in a control room and is connected to remote analog or digital gas detectors. It offers Modbus® RTU RS-485 or BACnet® MS/TP RS-485 output signal for communicating with a Building Automation System.
