Armstrong Monitoring Corporation (AMC)

- Model 1ACOsvp - Standalone Carbon Monoxide Monitor with ECM Fan Output



The AMC 1ACOsvp Gas Monitor provides an economical standalone carbon monoxide monitoring package, incorporating state of the art sensing technology and micro-controller based design to provide accurate gas detection capabilities within a compact package.

It features a configurable analog output circuit that can be set independently of sensor scale, and is jumper selectable for 4,20 mA, 0-20 mA, 0-10 VDC, or 2-10VDC. A second integral transformer allows it to power the control circuits of the latest ECM fan motors, creating a highly energy efficient detection and ventialtion control system.

It is ideally suited for smaller parking and/or service garages for detecting the exhaust of gasoline, propane, or natural gas powered vehicles, where the interlocked exhaust fans are being controlled by the latest generation of ECM fan motors.
