Intruder Alarm Faults We Commonly See in Gloucestershire

Intruder Alarm Faults We Commonly See in Gloucestershire - Intruder Alarm Services by Affinity Fire & Security

Our engineers regularly service intruder alarm systems across Gloucestershire and encounter a consistent range of faults. Understanding these common issues helps businesses take proactive steps to maintain system reliability.

Common Faults We Find

1. Detector Sensitivity Issues

PIR detectors can become less responsive over time due to dust accumulation on the sensor lens. Conversely, environmental changes such as new heating systems or direct sunlight can cause unwanted activations.

2. Battery Failures

Both the main panel backup battery and individual wireless device batteries degrade over time. A failed backup battery means the system will not function during a power cut — precisely when protection is most needed.

3. Door Contact Misalignment

Door and window contacts can become misaligned due to building settlement, wear on hinges, or accidental damage. This results in either false alarms or, worse, zones that are not providing protection.

4. Communication Failures

Systems connected to monitoring centres rely on telephone lines or IP connections. Changes to telecoms infrastructure, network outages, or misconfigured settings can break the communication path without the user being aware.

5. User Code Issues

Staff turnover can lead to active user codes assigned to people who have left the business, or insufficient valid codes for current staff, leading to the system not being set.

Preventative Maintenance

Regular professional maintenance identifies and resolves these issues before they compromise security. Get in touch with our team for intruder alarm servicing across Gloucestershire.
