The DS10 door/window sensor works with any X-10 security system. This sensor sends a wireless radio frequency signal to the main console when a door or window is opened.

When the system is not armed, the console chimes when a door or window is opened. When the system is armed, the alarm is tripped when a door or window is opened. A delay switch on the front of the door/window sensor lets you select if an alarm is tripped immediately, when the door or window is opened, or after a preset entry delay when the system is armed in delay mode.

• Supervised door / window sensor ( sends a self checking signal every 90 minutes).

• Uses full 16 bit Code for RF transmission.

• Battery operated with low battery detection.
