Do I need a maintenance contract?

A maintenance contract is important to maintain proper functioning of your alarm system. Audible alarm systems should be checked once a year.  A system that signals to an approved Alarm Receiving Centre needs to be serviced or maintained twice a year.  Replacement of batteries before they degrade ensures alarm signalling functions correctly without false alarms or signalling failure due to power interruption. An NSI approved installer will also provide a 24/7 emergency number to contact the duty engineer in the event of a problem.
