Fault guide: alarm system showing a persistent tamper fault
Clear a tamper fault preventing the alarm from arming properly. This page covers the causes worth checking on edge recording (SD card) systems, what you can safely check yourself, and what an engineer does on the visit.
- Fault: alarm system showing a persistent tamper fault
- System in view: edge recording (SD card) system
- Priority: worth dealing with quickly rather than leaving over a weekend
Symptom
Fault appears linked to a particular device or area
Check first
Look at the panel log to identify which zone or device is reporting the tamper
Likely cause
Loose termination inside a device or the panel
Why it happens
- Loose termination inside a device or the panel
- A wire that has worked loose at a screw terminal can present intermittently as a tamper fault rather than a constant one.
- Detector or keypad cover not seated correctly
- Every device on the system has a tamper switch that trips if the cover is not fully closed and clipped in place.
How this shows up
The underlying question is simple, clear a tamper fault preventing the alarm from arming properly.
- Fault appears linked to a particular device or area
- Panel displays a tamper fault that will not clear
Burglar alarm repairs
- Alarm fault finding
- Component replacement
- System health checks
How this looks on edge recording (SD card) systems
Diagnosis on a edge recording (SD card) system follows its own sequence, because the failure points sit elsewhere.
- Camera with an SD card slot
- Stores footage locally within the camera unit.
- High-endurance SD card
- Rated for the continuous write cycles CCTV recording involves.
What you can rule out yourself
Neither involves opening equipment or touching mains wiring, and if one resolves it, you have saved a callout.
- 1Look at the panel log to identify which zone or device is reporting the tamper
- 2Inspect accessible cable runs for obvious damage
Keeping it from recurring
Check device covers are properly seated after any cleaning or maintenance work near sensors and keypads.
What the visit involves
This fault is worth dealing with quickly rather than leaving over a weekend.
- 1Re-terminate any loose connections found at the device or panel
- 2Repair or reroute cable damaged by rodents or other causes
Where this approach stops
Storage capacity on a card is limited compared with a dedicated recorder's hard drives, so retention is much shorter. SD card health and remaining life checked periodically, with replacement built into the service schedule rather than left until failure.
Chattenden: the practical picture
In Chattenden (ME3) we work regularly around Lodge Hill Lane and Sutherland Avenue. On the A228 corridor onto the Hoo peninsula; quick reach to Strood and the M2 J1.
On a home with a hot tub, this fault usually matters most at one point
- Side gate used to reach the rear without passing the house
- That is the access route that needs to be covered reliably, which is why alarm system showing a persistent tamper fault there is worth fixing rather than living with.
- Lighting keyed to the same zone
- A well-lit hot tub area is a normal amenity feature; it also removes the cover that darkness gives an intruder using that route.
