Grade 2 Single Reed Roller Shutter Door Alarm Contact 0.45 Meter Knight

The F10A  Heavy Duty Rolling Shutter /  Garage Door Contact with 18  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 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 18  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
