Fortress Security Store (TM) Contact Sensor for S02 or GSM Security System – Window & Door Sensors

The most likely method of forced entry into a home or office is via a door or windows. That’s why it’s so important to have contact sensors attached to the windows and doors on your home – at least on the ground floor.

These magnetic sensors can detect any time a window or door is opened. If the alarm is armed, it’ll be triggered – setting off the siren and, in the case of the S02/GSM system will call a sequence of designated numbers until someone picks up.

Each pair of sensors requires one ‘N’ battery.
