SENTRY PRO WIRELESS DOOR/WINDOW CONTACT

Item in Stock (478 Available)

The Sentry Pro wireless door window contact uses advanced signal analysis and processing technology to avoid false alarms.

Fully compatible with both the Sentry Pro and Sentry Smart Wifi range of house alarms.  As the name states this device can be fitted to both doors and windows.

You can place either part on either the fixed or moving part of the door or window. You will see many door window contacts that state you cannot fit them onto a metal surface, this is because the metal can cause what is known as a null spot, this is an area around the sensor where either the device cannot send out signals or receive them.This is not the case with this door window contact, you can fit them to any double glazed window frame or garage door with no issues. They are very small and compact.

Each contact will come with a fixing kit that can be either stuck on or screwed in place.

We suggest if fitted in a hot location that they are screwed in place, as in heat the glue on the back of the sensor can become pliable and weak as it softens. As with the PIR, if purchased at the same time as an alarm system we will link this in for you.
