10mm pencil type flush contact, 4 wire.
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.
