Monitor doors and windows with this improved Long Range Wireless Door / Window Sensor. It has a longer range and longer battery life than the standard door / window sensor. Magnetic contacts can be replaced with most NC (normally closed) sensors sold at Smarthome. The Long Range Wireless Door / Window Sensor cannot be switched to NO (normally open) sensor capability. Requires 2 AA Batteries (not included).
Note: This unit does not directly send X10 signals so it must be used with the security console.
