Senva TGM-ACX-A : Metal Wall Mount Toxic Gas CO Sensor/Controller, 0-10V, 0-5V, 1-5V and 4-20mA Selectable Output, LCD Display, 7-Year Warranty
The Senva TGM-ACX-A is a metal wall-mount toxic gas carbon monoxide (CO) sensor/controller with selectable output options including 0-10V, 0-5V, 1-5V, and 4-20mA. It features an LCD display and comes with a 7-year warranty. The TGM-ACX-A has various applications, such as ensuring adequate air flow in occupied spaces, ideal for parking lot garages, alerting occupants of elevated gas levels, and directly controlling exhaust fans. The power supply requirements are 15-30VDC/24VAC, with programmable analog outputs and CO output scaling options. The fan relay and alarm relay characteristics, along with setpoints, are detailed in the specifications. The display includes a 3-1/2 digit LCD indicating CO ppm, and LEDs provide visual cues for normal, warning/fan relay, and alarm/alarm relay statuses. The audible alarm exposure is a 85dB piezo transducer, and the CO sensor is electrochemical with a life expectancy exceeding 7 years. The coverage area is 5000-7500 square feet, and the metal enclosure is made of powder-coated steel/acrylic, adhering to NEMA 3R standards. The device is compliant with UL61010-1 and holds UL, cUL, and CE certifications. The dimensions are 4.0”5.0”h x 4.3”w x 2.25”d, with pre-drilled mounting for a 2x4” electrical box, and it has an IP20 rating.
