About this item

Door/Window Contacts are perfect for use in situations where it is not suitable to fit PIR Detectors, for example where there are pets or animals. Q: Hi can you advise me please on a magnet reed switch that I can fit to a wooden gate so it alarms when opened, I bought some last week and it only alarms when the gate is shut , I want it to alarm when opened, I am going to use a 12v dc buzzer and strobe, and a plug in timer so it only alarms sets it self at 12am to 5am, A: Usually alarm contacts are Normal closed (NC) circuits meaning when the magnet is engaged the circuit is made I would also advise that alarm contacts arent designed to cope with power being run through them as the reed switch is so fine https://www.ebay.co.uk/itm/PT1-60-60-second-60-minute-Precision-Timer-Alarm-Module-For.
