What to do if my FRIEDLAND SA1 siren sounds when disarmed or not triggered?

If your FRIEDLAND Security System siren sounds when the system is disarmed or hasn't been triggered by an intruder, it could be due to several reasons: * A Detector tamper switch may be activated: Check that the battery covers of all detectors and Keypads are securely and fully fitted. * A Personal Attack Alarm may have been operated from a Remote Control or Keypad. * The Jamming detection circuit may be in operation. * A Detector may be giving false alarm signals.
