The F102 Heavy Duty Rolling Shutter /  Garage Door Contact with 2m of Armoured Sleeving from Knight Fire & Security is a potted single-reed contact alarm ideal for placement in rolling shutter doors in moderate-risk domestic or commercial areas.

When wired to an alarm system, these contacts will trigger the sounder if the gap opening exceeds 50mm, and as the contact creates a circuit to your security system, wire tampering or a forced break of the circuit elsewhere will also sound the alarm.

What is meant by the term Grade 2?
Grade 2  refers to the grade of the intruder alarm system you have on the premises, especially if you are depending on the alarm system for insurance cover in your home or business. A Grade 2  Alarm basically means Low to Medium Risk, Intruders are expected to have a  little more knowledge of the alarm system and use a general range of tools and some specialist equipment.

This contact features a durable weatherproof metal body for commercial uses, and 2M of armoured sleeving to protect the connecting cable to your system.

Note: ensure that arrow on magnet lines up with the dot on contact on housing for maximum operating gap and lateral tolerance.
