The C30 4 Core Recessed & Flush Pencil Style Single Reed Door/Window Contact in White from Knight Fire & Security is ideal for placement on doors or windows to be wired into your intruder alarm system.

When wired into an intruder alarm system, these contacts will triger the alarm and sounder if the opening gap exceeds 15mm. As the contact creates a circuit in your security system, wire tampering or a forced break of the circuit elsewhere will also sound the alarm.

What is mean't by the tearm '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.

The contacts are suitable for reccessing or mounting on the inside frame of your chosen door or window, and are paintable for a discreet fit.
