Up to three (3) sensors can be installed to main control to meet space coverage requirements
Features
Universal power inputs: 110/220 Vac and/or 12–48 Vdc input
Strobe light for visual alerts
Sensor status indicator LEDs on the main control
Modular design for optimal placement of sensor(s)
Installation
Wall or 2-gang junction box mountable
Mechanical relays are easily accessible:
Warning 25% relay, 15 A @ 120 Vac; 10 A @ 277 Vac; 10 A @ 28 Vdc
Alarm 50% relay, 0.5 A resistive @ 28 Vdc, 0.5 A @ 125 Vac
Redundant power supply capability; dual AC and/or DC power supply connections (DC power supply will operate as backup power source)
Indicator LEDs can be tested by pushing the red “TEST” button
Sensors can be tested in the field with the P/N CH4-TESTKIT
Detector can operate exhaust fans and building alarms / SCADA systems:
Warning Settings: Should the concentration of methane gas in the air surrounding the sensor reach 25%LEL by volume, the “25%LEL Warning” yellow LED will light up on the main control of the unit. In addition, the 25%LEL internal relay will energize and can be used to activate an external exhaust fan.
Alarm Settings: Should the methane gas concentration reach 50%LEL by volume, the “50% Alarm” red LED will light up, the strobe will flash and an audible alarm will sound. In addition, the 50%LEL internal relay will energize and can be used to activate a building management/alarm system (via SCADA/Modbus).
