A security system that is serviced yearly is a security system that is going to be reliable and functioning correctly when needed. Many security companies install security systems, hookup the alarm monitoring and you then you don’t hear from them for years until you call them with a problem.
A good security company will offer you a yearly maintenance agreement and explain the value of this to you. Most security systems do indicate when there is a problem by indicating on the keypad with a trouble light and beeping. The will system will also call the alarm monitoring service report the trouble. This is the case for Low Battery, Loss of supervision etc but not the case if you have problems with sensors or general wear and tear. This can only be found by the technician performing an inspection and full test on your system.
The cost of not doing a yearly inspection on your security system can be great and cost you far more in the long run if the system doesn’t function correctly if an intrusion or fire occurs.
