EAC Fire & Security recently completed an intruder alarm upgrade in Wimborne, Dorset, replacing an ageing alarm control panel and repairing several faults affecting the property’s existing security system.
During our inspection, we discovered multiple problems, including faulty motion detectors, bypassed tamper circuits and a faulty panic alarm (PA) button. To restore reliable operation, our engineers installed a new Orisec CK-20 intruder alarm control panel, replaced faulty motion sensors, fitted a new backup battery and reconnected the tamper circuits.
The completed work brought the existing alarm system back into good working order without requiring an entirely new installation.
Inspecting the Existing Intruder Alarm System
When our engineers arrived at the property in Wimborne, the existing intruder alarm was in poor condition and required several repairs.
The original system featured an older Omnicron 7000 alarm panel, with faults affecting various security components.
Our inspection identified the following issues:
- Faulty motion detectors: Existing PIR sensors were no longer operating correctly.
- Bypassed tamper circuits: Tamper protection had been linked out, preventing those circuits from providing their intended protection.
- Faulty panic alarm button: The existing PA button was identified as defective.
- Ageing control equipment: The original alarm panel required replacement.
These issues can significantly reduce the effectiveness of an intruder alarm. In particular, bypassed tamper circuits may prevent the system from detecting interference with protected equipment or cabling.
Rather than replacing every component unnecessarily, our engineers assessed the existing installation and identified the equipment and wiring that required attention.
Replacing the Old Alarm Panel with an Orisec CK-20
The main part of the project involved removing the outdated control panel and installing a modern Orisec CK-20 intruder alarm system.
The Orisec CK-20 provides a replacement control panel for managing the property’s alarm detection circuits and security devices.
Our engineers inspected the existing cabling, connected the necessary circuits to the new panel and configured the system for the property.
The new equipment also features an illuminated keypad and display, making the alarm easier to operate and maintain.
This approach allowed us to upgrade the central alarm equipment while addressing faults within the existing installation.

Replacing Faulty PIR Motion Sensors
Several motion sensors within the property were faulty and required replacement.
PIR (passive infrared) motion detectors form an important part of many domestic intruder alarm systems. They detect changes in infrared radiation associated with movement within their monitored areas.
When a motion detector becomes faulty, it may fail to detect movement correctly or contribute to unwanted alarm activations.
Our engineers replaced the defective motion sensors to restore reliable detection throughout the relevant areas of the property.
Restoring the Alarm Tamper Circuits
One of the important issues discovered during the inspection was that the existing alarm’s tamper circuits had been linked out.
Tamper protection is designed to detect interference with alarm components, such as attempts to open equipment housings or interfere with connected wiring.
When these circuits are bypassed, the system may no longer identify certain forms of interference.
As part of the upgrade, we reconnected the tamper circuits to restore their intended functionality.
This was an important step in bringing the existing security system back into proper working order.
Installing a New Alarm Backup Battery
The alarm’s backup power supply was also renewed during the installation.
Our engineers fitted a new 12V 2.1Ah rechargeable backup battery within the Orisec CK-20 panel.
A working backup battery helps an intruder alarm continue operating during a mains power failure.
Backup batteries deteriorate over time, which is why battery condition should be checked during routine alarm servicing and replaced when necessary.
For homeowners experiencing repeated alarm faults, low battery warnings or issues with older systems, our alarm maintenance and repair services can help identify the underlying problem.
Completed Intruder Alarm Upgrade in Wimborne
Following the installation of the Orisec CK-20 control panel, replacement motion detectors, new backup battery and restoration of the tamper circuits, the alarm system was returned to good working order.
This project demonstrates that an older intruder alarm does not always require a complete replacement.
Where suitable existing wiring and equipment can be retained, a targeted upgrade can provide an effective solution while avoiding unnecessary additional work.
The property now benefits from updated alarm control equipment and restored detection and tamper protection.
