Intruder Alarm Takeover & Recommission — Christchurch

EAC Fire & Security was recently engaged to take over, recommission, and fully service an intruder alarm system at a residential property in Christchurch . The existing system had been deactivated and the owner wanted it brought back into full operational condition.

When we arrived, the following issues were noted:

• The alarm had been turned off / disabled
• The backup battery was extremely old (about 22 years)
• The external bell (siren) was faulty
• Access codes and user configuration were outdated
• No recent system testing or walk test had been done

Our team carried out the following steps:

• Power & Panel Reactivation
  Enabled the control panel, cleared old fault states, and brought the system back online.
• Code Reset & Access Configuration
  Reset master, user, and installer codes to ensure full system access and security.
• Battery Replacement
  Removed the aged battery and replaced with a new, correctly rated sealed battery to ensure system reliability in mains-loss conditions.
• Bell / Siren Replacement
  Fitted a new external bell/siren, properly connected and tested for sound output.
• Complete Walk Test
  Triggered all sensors and detectors zone by zone to confirm correct detection, triggering, and reset behavior.
• Part‑Set / Partial Mode Programming
  Configured a part‑set mode (e.g. “night mode”) so that the system can be partially armed while permitting movement in certain areas.
• System Health Verification
  Checked tamper, sabotage, wiring integrity, and verified overall system status was healthy (no faults or alarms).
• The intruder system is now fully functioning and secure
• Correct power and battery backup restored system reliability
• The external bell/callout system is working as designed
• Owners now have new secure access codes
• Part‑set functionality gives flexible use (e.g. night mode)
• Peace of mind restored that the system is ready for everyday use
