Product Overview
The DHM-303T Contact Sensor can be used to detect whether a door or window is open or closed. You can use
this to provide security for windows, or to monitor entry and exit through a doorway, and can be used in tandem with
other sensors and keypads to monitor and control access to an area.
The DHM-304T Motion Sensor can be used to detect motion in an area. You can change the sensor's motion detec-
tion sensitivity to help you nd the right balance to detect movement without false alarms.
Each sensor and keypad periodically sends a "heartbeat" signal to the gateway, which noties you when the batter-
ies in a sensor need to be changed, or if a sensor is out of range.
The two USB ports allow you to expand your home monitoring system by adding adapters such as a DWM-156 3G
dongle for a 3G fallback Internet connection, or a DHM-101 Z-Wave USB Dongle to allow for connection to Z-Wave
devices.
