Security System
Maintenance and
Repairs

Like any technology, Security alarm systems can experience issues that require repairs.

Here are some common faults and how our technician’s generally addresses them:

1. False Alarms: Alarms are triggered without an actual security breach, often caused by sensor malfunctions, environmental factors, or improper installation.
2. Battery Failures: Wireless alarm systems rely on batteries, which can lose charge or fail over time. The batteries in wireless reed switches and PIR sensors generally last about 3-5 years. Backup batteries in alarm systems should be replaced every three years, or sooner if there has been an extended power outage.
3. Connection Issues (Wired Systems): Faulty wiring can disrupt communication between the alarm control panel and sensors or other system components.
4. Communication Failure (Monitoring Systems): Alarm systems connected to monitoring centres may lose communication due to network, phone line, or cellular issues. It is best practice to conduct regular tests with your alarm system to confirm it is still online and reporting to our monitoring centre. If you are unsure how to do this, please contact our service department to assist you with your particular setup and the testing procedure.
5. Sensor Tampering or Malfunctions: The system might trigger tamper alerts due to the control panel or sensor covers being opened or damaged, causing them not to trigger the alarm.
6. Control Panel or Keypad Malfunctions: The main control panel or keypad becomes unresponsive, preventing system operation. 
7. Power Supply Issues: The system may lose power due to issues with the main power supply, causing system downtime. 
8. Outdated Software or Firmware: System software may become outdated, leading to vulnerabilities or malfunctions. 
9. Siren or Bell Failure: The siren or alarm bell doesn’t sound when the system is triggered. This is very common, we recommend scheduled technician testing every 6 months for a Commercial property or every 12 months for a residential property based on the frequency of use to ensure both of these components are in working order.

Technician’s Approach

Diagnosis: Our security technicians use diagnostic tools to determine the root cause of the issue, such as checking for error codes, inspecting hardware, or testing connections.

Testing: They conduct a series of tests on system components (e.g., sensors, control panel) to ensure each is working properly.

Repair/Replacement: Based on the diagnosis, faulty components are either repaired or replaced.

System Reboot: After repairs, a reboot or reset of the system is generally required to verify that it is functioning correctly.

User Training: If necessary, our technicians may also guide you on proper system usage or maintenance to prevent future issues.

A well-maintained security system with regular check-ups can prevent many of these issues. Speak with the Eximm team today to schedule a service for your security alarm system.

In general to address these problems, an Eximm technician would:

• Perform diagnostics to isolate the root cause.
• Fix power, connectivity, or configuration issues.
• Repair or replace hardware as needed (cables, power supplies, hard drives).
• Update firmware and software to ensure system stability.
• Provide maintenance, including cleaning cameras and ensuring proper ventilation to avoid future problems.

Regular system maintenance can prevent many of these common issues from recurring. To schedule repairs to your CCTV Security Cameras, NVR or DVR or to proactively schedule a service of your system to avoid mishaps in the future, please contact our technical security team today!

Common issues with video and audio intercom systems often require a variety of troubleshooting steps.

Here’s a breakdown of the typical problems and how a technician might address them:

Common Issues/Faults:

1. Power Failure: No lights, no sound, or the unit not turning on at all.
2. Poor Audio Quality: Static, crackling, or faint/muted audio.
3. No Video or Poor Video Quality: Blank screen, flickering, grainy, or distorted video.
4. Call Button Malfunction: Call button doesn’t work or requires excessive pressure.
5. Door Release Mechanism Issues: The door doesn’t unlock when triggered through the intercom.
6. Intermittent Functionality: The system works sporadically, with either audio, video, or unlocking failing sometimes.
7. Interference or Noise: Background noise or interference in the audio or video signal.
8. Wi-Fi or Network Connectivity Issues (for IP-based systems): Intercom system disconnecting from the network or slow performance.
9. Intercom app issues: Not receiving intercom calls to a mobile phone

General Technician Process:

Inspection & Diagnosis: The technician will first assess the system, visually inspecting wiring, hardware, and testing audio and video feeds.

Testing Components: Technicians will test key components (power supply, camera, microphone, speakers, etc.) to identify faulty parts.

Repair & Replacement: Based on the diagnostics, the technician will repair damaged wiring or replace faulty parts.

System Reconfiguration: After repairs, the technician may update the software, reconfigure the network, and test all features to ensure smooth operation.

Final Testing: A thorough test of the system, including audio, video, door release functionality, and overall communication quality, ensures everything is working.

Each issue requires a methodical approach, ensuring that the problem is accurately identified and fixed to restore the system’s functionality.

Common issues or faults in access control systems typically fall into a few key categories, and how a technician addresses them depends on the specific issue.

Here are some of the most common faults and general approaches a technician might take to fix them:

1. Card Reader Malfunctions: Card readers may stop responding, fail to read access cards, or give false negatives. 
2. Door Lock Failures: The door may not lock or unlock as expected. 
3. Software Issues: Access control software may not register or log access events, or may malfunction, preventing control of the system. 
4. Power Supply Issues: Entire system failure, intermittent power, or device failure. 
5. Network Connectivity Problems: Controllers or card readers connected via the network lose communication with the central system. 
6. Faulty Wiring or Connections: Random system failures, intermittent access problems. 
7. Database or User Access Issues: Users may not be able to gain access due to permission issues, database errors, or incorrect card programming. 
8. Tampering or Security Breaches: Unauthorised access or attempts to bypass the system. 
9. Intermittent Functionality or System Freezing: The system operates sporadically or freezes entirely.

Preventive Maintenance

Our technicians recommend Regular maintenance of your Access Control System to prolong the lifespan of the devices. Maintenance can include the following:

• Testing all components periodically.
• Cleaning card readers and sensors.
• Checking wiring and connections.
• Ensuring the system firmware and software are up to date.
• Inspect electric locking hardware for correct operation. Clean and lubricate as needed.

By systematically diagnosing these issues, an access control system can be kept running smoothly with minimal downtime.
