GE Security TX-8010-01-1 DesignLine Garage Door Sensor, White.
The GE DesignLine Garage Door Sensor extends intrusion detection to garage structures, enabling users to regularly monitor the door's opening for complete home security. Once armed, if the garage door opens to a 45-degree angle, the sensor goes into an alarm condition which can turn on the siren and automatically call the central monitoring station. Under normal use, the sensor will transmit an open and close signal to the panel each time the garage door is opened or closed.
To prevent false alarms, this sensor comes equipped with a built-in one-second delay feature in case the garage door shakes during windy conditions. In addition, the sensor also sends a supervisory signal to the panel every 64 minutes and is equipped with a cover tamper for added security.
