GSM Alarm sensor flashing red light problem.

[Dave123456789]

Hi all

I’ve had a standard gsm alarm for many years no issues

Recently one of the sensors just flashes red multiple times when it senses movements. Normally it’s just once when sensing movement - not multiple flashes

despite battery change problem persists

I know it’s not a branded alarm so advice may be hard to find but hoping somebody may know why it’s playing up….

Meta AI reply when asking about red lights in a pit sensor (so generic response not specific to my alarm model)

A PIR (Passive Infrared) alarm sensor flashing red multiple times usually indicates a specific issue. Here are some possible reasons:
- *Calibration or Test Mode*: The sensor might be in calibration or test mode, often triggered by a power cycle. In this mode, it flashes red when detecting heat signatures.
- *Low Battery Warning*: If it's battery-powered, a flashing red light could signal low battery voltage.
- *Fault or Error Mode*: The sensor might be experiencing an internal issue, possibly due to power surges, interruptions, or environmental interference.
- *Sensitivity Issues*: High sensitivity settings can cause false triggers from minor environmental changes.
- *Dirt or Debris*: A dirty lens can scatter infrared energy, causing erratic behavior.

To troubleshoot, try:
1. Checking and cleaning the lens
2. Adjusting sensitivity settings
3. Replacing batteries (if applicable)
4. Resetting the sensor via power cycle

If issues persist, it might be worth consulting a professional or replacing the sensor

UNFORTUNATELY I DO NOT KNOW ANY MASTER CODE ETC SO WOULDN’T KNOW HOW TO RESET ETC as somebody else installed it

these are or were sold on eBay for very little for the whole system, 30-50 for the panel and a load of sensors.

Took one out years ago after it had failed.

No idea if you can still get units on eBay to replace like for like for little money, but isn’t something any of the installers on here are likely to even look at as parts can’t be bought from a reputable distributor

Hello do you know if I’d need like a master engineer ?
Even if I was able to source a sensor - the installer is long gone andt they are the ones who programmed it…

Having spoke to my dad he seems to now recall accidentally dropping it when changing battery - which has maybe caused it to fail

Thanks can’t see mine on there but I found a very similar one on Amazon … maybe best just to live with one sensor less as even if I got one more sensor wouldn’t know how to program it
