The Macurco GD-2B Hardwired Natural Gas and Propane Detector will monitor a residential location for Methane (Natural Gas (NG) or Liquid Propane (LP). This is a Normally Open SPST Sensor with a Normally Closed Trouble Output. The device has a product life of 10 years.
When mounting the sensor, the proper location will depend on the type of gas being used in the home. For natural gas or methane, mount the sensor an a wall about a foot below the ceiling. For liquid propane, mount the sensor about one foot above the floor. The sensor should not be installed in kitchens or bathrooms, as doing so may result in false alarms.
The module is designed for indoor use only, and it should not be exposed to temperatures below 32 degrees Fahrenheit or above 120 degrees Fahrenheit. A face plate and mid plate for mounting come included. During normal operation, the LED light will appear solid green. The light will turn red when the sensor is activated. Additionally, a flashing amber light indicates trouble.
The device also features a switch that is used for testing, silencing and resetting the sensor. Pressing and releasing the button immediately will have the sensor enter its self-test mode. Pressing and holding the button for more than five seconds will have the buzzer sound for two cycles. If an alarm occurs, you can temporarily silence the device with this button. You can also temporarily silence during end of product life warning. Please see the user guide for more detailed information.
Note: Alarm Grid also offers a Form C version of this same sensor.
