"My Alarm is 7 years old,
it has never been touched since it was fitted -
surely it's like brand new still?" |
|
Your
intruder alarm works 24 hours a day - 365 days a
year.
Even if
you don't arm or disarm it the printed circuit
board, power supply unit and battery
within your system should have annual checks to
ensure stability!
