CONSPEC’s P2621-CO/VC Carbon Monoxide Monitor & Ventilation Fan Controller was designed to be a stand alone or multi-unit CO detector and fan controller. A single controller will provide up to 10,000 square feet of protection.

Multiple controllers can be installed and easily connected without the need for a central panel by a simple series connection of the controllers. LED indicator lights clearly show the status of the monitor and a large LCD display continually shows the CO levels being monitored. After a power loss or in the event of a malfunction, the controller activates the ventilation system.
