I am getting random beeping from my alarm system – Whats wrong?
The problem could be due to: • Loose connections. • Cold air entering back of alarm – cable entry holes too big. • Cables running too close to interface from old fluorescents, inductive loads, etc. • Electrical interference (EMI). • There is another device in the property that is the source of the beeping. Loose connections on the terminals of the alarms, or from the mains supply. Cold air entering the back of the alarm can cause condensation on the circuitry. This problem mainly occurs on first floor alarms where cables enter the back of the alarm and, either the hole for the cable is too large, and/or the roof insulation has not been refitted correctly. Modern fluorescents rarely cause a problem, but very old switch-start units with a poor earth can. There should be no problem installing an alarm system on a circuit with modern fluorescent lights on them, but avoid running the alarm cables by the side of this circuit. The same applies to circuits powering a central heating boiler, fo
