A regular periodic program of preventive maintenance can assure the homeowners that their security system is properly functioning and reliable. The frequency of the preventive maintenance program should never be less than at least once annually, with quarterly or semi-annual programs at the discretion of the homeowners. However, the more complex the security system, the more frequently it should be checked.
While there aren’t any disadvantages to frequent preventive maintenance checks to a
Prevention of false alarms
Fewer service or problem calls
Desired changes implemented when needed
Reliability of the system
Manufacturer’s upgrades applied regularly
Developing or potentials problems corrected before they cause the system to fail
To be in compliance with National Fire Protection Association (NFPA) 72 guidelines, a home security system must be
The testing procedure performed by the homeowner should include the following tests:
Arm and disarm the system Every person with a key to the home should perform this test.
Fail all exterior ingress points Test each window and outside door contacts and motion sensors. The homeowner should alert the monitoring service before the testing begins and when it is complete.
Test smoke and CO detectors
Press the test
The testing performed as a part of a preventive maintenance check should approximate the testing performed during the original acceptance tests (see Chapters 32 and 33). If a local emergency services authority, such as the police department,

The prevention of false positives or false alarms should be one of the primary purposes of a regular maintenance and testing procedure. There are many causes for false alarms, including user errors, power or battery problems,
A security sensor or contact that is intermittently reporting false alarms may have power or continuity issues caused by cable or wire problems. A window or door contact that is even slightly misaligned may generate a false alarm even if the window or door is closed and locked. All doors and
When troubleshooting a home security system, you must first determine whether the problem is being caused by one of the four major areas of a security system: contacts, sensors, or detectors; the security system controller; wiring; or the interface to the telephone system.
A regular periodic program of preventive maintenance can assure the homeowners that their security system is properly functioning and reliable. The frequency of the preventive maintenance program should never be less than at least once annually, with quarterly or semi-annual programs at the discretion of the
The advantages of periodic preventive maintenance on a home security system are: prevention of false alarms, fewer service or problem calls, desired changes implemented when needed; reliability of the system, manufacturer’s upgrades applied regularly, and potentials problems corrected before they cause the system to fail.
In compliance with NFPA 72 guidelines, a home security system must be tested at least once per year. If a local emergency services authority, such as the police or fire department,

The opening door blocks the scanning field
The sensor is set too high or too low
Too many objects are in the room
Which of the following should be included in the troubleshooting process for a security system controller?
Reload the controller’s backup
Apply all manufacturer’s upgrades
Test the system
Disconnect all zone devices before troubleshooting the system controller
When troubleshooting NC contacts wired in series, what procedure should be used?
Test all contacts in the series
Disconnect all but the first contact and add the contacts back to the system one at a time
Disconnect all but the last contact and add the contacts back to the system one at a time
NC contacts should be wired in parallel
Which of the following is a good troubleshooting technique for a suspected faulty contact or sensor?
Disconnect the suspected device and retest the system
Disconnect all but the suspected device and retest the system
Replace the suspected device with a known-good device and retest
Replace the suspected device immediately
When performing a visual inspection of contacts and sensors, which of the following should you be looking for?
All of the above
What is the national standard that governs the installation and testing of fire alarm systems?
When troubleshooting an RJ-31X connection, which of the following steps should be performed?
Check jack and plug for damage

None of the above
B. False alarms can be embarrassing and costly for a homeowner.
D. Improper training is likely the underlying reason behind the number of user errors resulting in false alarms.
E. All of these are possible causes for any security device to generate a false positive.
B. The opening door blocks the scanning field. Improper placement of a motion sensor can defeat its function.
Before any other action is taken, the system should be retested completely to ensure that the
B. Disconnect all but the first contact and add the contacts back to the system one at a time. However, if the devices are wired in parallel, they can be tested individually.
C. Replace the suspected device with a known-good device and retest. Replacing a suspected device with a known-good device is a quick way of identifying or eliminating a device as a problem.
E. All of these choices should be included when visually inspecting security devices.
C. Many communities use this standard as the local standard as well.
