Security Alarms do need Servicing, but it is not crucial that they are serviced every single year.
Sometimes your insurance company will either encourage or even insist that you have your security alarm serviced on an annual basis and my company does provide this service and issues a completion certificate. Some insurance companies offer a percentage off your policy because you about the security alarm serviced each year.
But the actual fact is the hardwired security systems main control battery can have a lifespan of up to 5 years. The battery in the control panel is there as a secondary supply, so the if you have a mains power cut, the system will be held and still be functioning for good number of hours without any problems caused to the system or any false alarm.
But having said that the commonest fault that you get with a hardwired security alarm is that the control panel battery has not been replaced for a number of years and is lost its power and as soon as the mains electric goes off for some reason, one of two things will happen. As soon as the mains electric goes off and the control panel

l dies because its battery is not functioning. At this point if the outside self acting siren box still has battery power left, it will go into alarm condition thinking that the system is under attack. The outside siren box is called “self acting” because it has its own battery backup and circuit board, which there primarily because if a burglar gets into the building and destroy the alarm control panel, the outside siren would continue to sound and strobe light would continue to flash. It would not be possible to stop the siren box without getting up to with ladders and disarming it, which is obviously an advantage when an intruder breaks into the premises. But this advantage does become a disadvantage in mains power failure when the control panel is got a flat battery because the siren box cannot be stopped without putting up ladders and disarming it from outside. The worst scenario is if this happens during the night when people have a power failure while sleeping, obviously this can cause quite a problem.
But in the above example, if the outside box as also lost all its battery power, it obviously cannot go into alarm condition when the mains failure happens and the battery in the control panel doesn’t hold the system. So you effectively have a completely dead alarm system until the mains power comes back on and then what usually happens is the entire system goes into alarm condition. There are a number of security alarm control panels that actual lockout when the power comes back on and without clearing the panels memory of the system and reprogramming the panel, the user will not be able to use their security system again. The only good thing about this situation is that the alarm system will not continue to be alarm condition for more than 20 minutes, the maximum they are allowed to run.
When security alarm engineers conduct a service a hardwired system, they have a device for checking the amount of current still left in both the systems batteries. There is also a test procedure for testing each individual circuit from the control panel and checking its impedance and that the sensors are working correctly.
It is deftly not a bad idea to have your alarm system serviced every year even though the batteries may not need replacing that often, because you will know the entire security alarm is functioning correctly and you will encounter any problems with your insurance company claiming you had defective alarm due to its lack of service and testing.
Wireless Security Alarms do need servicing at least every two or three years for sure because they have batteries in each individual sensor which are usually alkaline batteries. Once again if an alarm engineer performs the alarm service they will do a full what test of the system to make sure that all senses are functioning properly including the outside siren box.
