• Protect doors and windows by linking the reed switch and magnet to an alarm system
• Surface mounted with an approximate operating gap of 20mm providing you with a more sensitive security system
• Five terminal contactsWhat can I use the reed switch for?
The surface mounted contact reed switch is useful if you want to protect windows and doors whilst you’re away from home. Once linked up to a security system, if an intrusion has occurred (with a gap exceeding 20mm) the alarm will sound.
What does the reed switch do?
When a door or window has been affixed with the surface mounted reed switch and is closed, a circuit is created with the connected alarm system. When you open a door or window (with the alarm system activated) this once completed circuit breaks, sounding the security alarm. This means that even if someone were to cut the wiring that connects the reed switch to the alarm system’s panel, the alarm will still sound.
Where can the reed switch be used?
The distance between the reed switch and magnet can be approximately 20mm before the alarm starts to go off, therefore in order to reduce false alarms it is ideal for you to locate the reed switch and magnet on a relatively flat surface.
What will I need to get this connected to the security system?
In order to get this reed switch connected to your security system you will need a four core alarm cable (for example order code: XR89W) to run from your security system panel to the reed switch.
Underneath the reed switch you will notice five screws which will be for the wires in the alarm cable, three of the screws will be used to make security loops (brass in colour) and two will be used to connect to the reed (silver in colour), establishing an alarm loop.
