Key Maintenance Tasks and How To Perform Them

Hands-on security system maintenance revolves around a core set of checks and procedures. Learn how to perform key tasks correctly.

Testing Sensors and Detectors

Activate each sensor intentionally, including door/window, motion, smoke, glass break, flood, freeze, heat, etc. sensors.
Verify the control panel registers the activation and displays the right zone or ID.
Ensure an audible tone sounds at the panel and programmed alert actions occur, like lights turning on.
Test during both disarmed and armed modes. The tone and alerts should be deactivated when disarmed on interior sensors.
For fire and smoke systems, test using real smoke, heat, or CO. Canned smoke substitutes don’t necessarily replicate real conditions.

Backup Battery Replacement

Identify the backup battery type required by the system. Common options are 12V sealed lead acid or lithium batteries.
Order an official replacement from the security system manufacturer if possible. If not, match specifications closely.
With the system disarmed, remove the old battery. Then install the new battery, verifying correct terminal polarity.
Attach included jumper wires from the battery to the alarm panel connection points.
Arm the system, disconnect AC power, and time how long the battery maintains functionality.

Sensor Adjustment and Calibration

Refer to your owner’s manual for sensitivity adjustment dials on each sensor model. Typically, you want them around 80% initially.
Walk test motion sensors to determine if their coverage patterns are incorrectly aligned. Adjust mounting brackets as needed.
For smoke and heat detectors, use a can of calibration gas to confirm they activate when exposed to the sensitivity threshold.
If sensors have excessive false alarms, reduce sensitivity slightly. Increase it if real alarm events are missed.
Have professionals handle calibration of more complex sensor types like glass breaks, laser grids, and camera analytics.

Communication System Verification

Trigger the alarm while monitored by your security provider. Confirm you receive the proper alert as programmed.
If self-monitored, intentionally activate a sensor and verify that programmed text or app alerts are sent to authorized contacts.
Regularly check the signal strength displayed on cellular communicators and contact monitoring center if it drops significantly.
For fire alarm monitoring, request a test of emergency communication annually wherein the fire panel contacts the monitoring service when activated.

Camera Maintenance

Gently clean external camera lenses and dome bubbles with microfiber cloth and lens cleaner or water. Avoid scratching.
Confirm cameras have the optimal field of view during walk testing. Adjust pan, tilt, and zoom as required.
Check video quality and camera alignment in both day and night conditions. Enable night IR illuminators as needed.
For PTZ cameras, test full functionality of movement axes and preset positions. Lube joints if needed.
Verify network video recorders (NVRs) are capturing all cameras properly under live and event recording.
