X10 DS18E/DS90E Door/Window Sensor for use with SC2800/SC9000

The DS18E/DS90E 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.

The sensor sends a "self-checking" transmission approximately every 90 minutes. The console will not arm if a door/window sensor hasn't reported in or if a door or window is opened (can be overdriven by pressing the console's Accept Button).
