DS90 Alarm Door/Window Sensor - Marmitek

The wireless door/window sensor for the expansion of your SafeGuard or TotalGuard alarm system.

Use and application:
The DS90 door/window sensor has a magnetic switch unit that triggers the console when a door or window where it is fixed to, is opened. This enables all the main entrances to a building to be protected. The sensor is battery powered and "connected" to the security system by radio which means that the installation of the units requires the minimum of effort but with the maximum effect. The sensor is monitored and failure of the sensor is reported by the base console. The DS90 door/window sensor has a contact for an extra wired sensor. These sensors need to be of type NC (normally closed contacts). There should not be any power on this contact (potential-free).
