Question 1

Keyfob will not arm the alarm

Accepted Answer

First, check if you are close enough to your caravan as the range of the keyfobs is 6M, and try moving closer. Second, check if the torch works; if not, the battery may be discharged and need replacing. Third, if the torch does work, check if the red light comes on when the arm/disarm button is pressed; in this case, the keyfob is likely faulty and should be replaced. Fourth, check if the other keyfob operates the alarm correctly. If the other keyfob also fails, confirm that the alarm has power by checking that the LCD screen on the alarm base unit is powered up if you have a charged leisure battery fitted. Ensure your alarm has power before trying the keyfob again. Finally, if the keyfob still doesn't operate the alarm, you will need to relearn the keyfobs using the relearn instructions found in the product page for the AS350 - Stinger Alarm System.

Question 2

AS310/AS300 keyfob doesn't arm the alarm

Accepted Answer

Possible cause: Out of range, discharged keyfob battery, faulty keyfob, lack of power to the alarm system, or unlinked/unlearned keyfob. First, check if you are within the 6M range of the caravan and move closer if necessary. Next, test if the torch works; if it does not, the battery may be discharged and need replacing. If the torch does work, check if the red light comes on when the arm/disarm button is pressed — if it does not, the keyfob is likely faulty and should be replaced. Test if the other keyfob operates the alarm correctly; if it does not, confirm that the alarm has power by checking if the green light comes on when you move around the van, and ensure power is available before trying the keyfob again. If the keyfob still doesn't operate the alarm, you will need to relearn the keyfobs by following the relearn instructions found in the product page for the AS300 - Stinger Alarm System.

Question 3

Battery not holding charge or not charging

Accepted Answer

Check 12V supply to Alarm. Check charging current inline with 12V supply (0-550mA). Perform a hardware reset to force charge cycle, which requires a 30-hour charge cycle.

Question 4

Low Battery

Accepted Answer

Possible cause: Often caused by damaged/broken Battery Switch on "Green" PCB pre May 2012 systems.. For pre May 2012 systems with a Green PCB, check and repair or replace the damaged/broken Battery Switch. Note that this was fixed post May 2012 on "Blue" PCB with the switch relocated to the PCB.

Question 5

Marker Lights not flashing on arm / disarm of system

Accepted Answer

Possible cause: Generally no 12V supply to Alarm System (Swift - Check Fuse 12).. Check Fuse 12 (for Swift models). Test 12V supply by listening for Awning Relay Switch on activation.

Question 6

Awning Light not operating

Accepted Answer

Possible cause: No 12V supply to alarm system, or an internal fuse inline with the awning circuit on the alarm PCB.. Check that the awning light works manually. If it does not work manually, there is a problem with the circuit, not the alarm. If it works manually but not via the alarm, check the internal fuse inline with the awning circuit on the alarm PCB.

Question 7

Key Fobs not working

Accepted Answer

Possible cause: Flat torch battery in fob, or fobs lost from the system during a power issue (e.g. flattened leisure battery).. Check the battery (Torch). If fobs were lost from the system, attempt erase and re-learn of fobs.

Question 8

Key fob Intermittent Operation

Accepted Answer

Possible cause: Stuck rolling code operation or local interference from other wireless equipment.. Try a few more arm attempts. Perform a local interference check for other wireless equipment and turn off. Check green antenna cable is free from all other cables.

Question 9

Instant Siren On Arming

Accepted Answer

Possible cause: PIR Fault or PIR Cable Fault. Usually accompanied by 5 beeps on disarm.. Reconnect cable at both ends.

Question 10

PIR False Alarming / Not operating

Accepted Answer

Possible cause: Incorrect sensitivity setting for climate condition, direct sunlight to PIR, tracker unit installed close to alarm system, or protective film still on face of PIR.. Check sensitivity for climate condition. Check for direct sunlight to PIR. Check if tracker unit installed close to alarm system. Ensure the protective film has been removed from the face of the PIR.

Question 11

System does not operate when connected to 12V supply

Accepted Answer

Possible cause: Batch issue with component C15, which leaks onto PCB.. Replace faulty capacitor C15 and clean PCB. If component-level repair is required, consult a specialist.

Question 12

Voltage Drop / Cold Weather False Alarms

Accepted Answer

Possible cause: Fault Signal output to 0v connection. Fixed Post April 2011.. Apply Green Wire fix: establish a connection from Pin 6 Fault Signal output to 0v.

Question 13

Lost Arm/Disarm Beeps

Accepted Answer

Possible cause: Base unit software/hardware glitch.. Perform a hardware reset. If the fault re-occurs at a later date following a reset, the base unit should be replaced.
