AS300/310 Alarm System

See our Frequently Asked Questions about the AS300/310 alarm system

The Stinger 300 is best suited to aftermarket applications or as a replacement for our older AS210 system. The Stinger 310 Swift alarm has a harness which is designed for installation in Swift 2010-16 where the EC400 system is in place.

Q. The alarm emits a beep about every 10 minutes?

A. The alarm is advising you that the internal battery is discharged, low or not connected properly.

Firstly check that the 12v supply to the alarm is present, as the alarm uses this supply to charge the battery.

Open the alarm base unit (see below). Check that the internal battery is plugged into the socket on the circuit board and that the battery on/off switch (located on the battery mounting plate) is in the on (I) position. Check the wires to the switch are intact and not damaged.

The alarm charges the battery periodically using an intelligent charging routine. To force this routine to start immediately perform a hardware reset (see below).

When the unit is charging the battery this can be seen by placing an ammeter in the 12v supply cable to the alarm. When set on a 1A range, the meter will show a pulsing charge current of between 0 and 550mA depending on the battery charge state. This charging cycle takes approximately 40 hours.

We do recommend changing the battery every 3 years,

Q. The alarm triggers (goes off) for no reason?

A. The alarm can be triggered for a number of reasons.

Common causes are sunlight shining directly on the PIR via the roof light. In these cases we recommend that roof light blinds are left closed when the alarm is armed.

Frost heaters which are left switched on in winter can trigger the alarm if they cause a sudden / severe temperature change in the caravan.

Cold draughts in front of the PIR unit can trigger the alarm. As the PIR is often mounted near a heating ‘blown air’ vent, draughts from this vent can be undesirable. Please ensure adjacent vents are closed when the alarm is armed.

In all of these cases, increasing the PIR pulse count can be helpful in eliminating any false triggers.

Q. The alarm sounds the siren a few seconds after arming?

A. This indicates that there is a wiring fault / bad connection / broken connection within the alarm wiring.

Check the cables for signs of damage, especially the PIR cable as this can often be ‘shot’ with a fixing staple.

Check the plug at the rear of the PIR. This is a RJ12 connector similar to those used on telephone handsets. Press the tab through the blue cover to release the connector, then reinsert and listen for the retaining clip to click into place.

Q. The alarm doesn’t produce the expected sequence of beeps.

A. This problem can occur if the key fob arm / disarm button is pressed for a longer than expected period. For standard arming and disarming you should just perform a quick press of the arm button, and not keep it held until you hear a beep.

For customers who have upgraded from the earlier AS210 alarm, the new Stinger alarm just requires a reasonably quick 'stab' on the button, unlike the earlier AS210 which needed a press and hold operation.

From feedback from customers who have reported this issue, the revised press operation has resolved the problem.

Q. I have a Stinger 310 fitted to a Swift caravan, can I add control of the awning light from the fob?

A. Yes, the Stinger 310 alarm is already wired for the awning light function, but this option has not been adopted by Swift, so the required wiring is not within the caravan harness.

To add the feature you need to run a twin cable from 2 connections at the back of the road lighting fuse box (this is located near the alarm base unit) to the awning light switch near the door. The wires are connected either side of the switch, allowing the alarm to work in parallel with the awning light switch.

Q. How do I perform a Hardware Reset?

If the above items fail to solve the problem, then performing a hardware reset (system reboot) may help.

The unit can be reset by firstly removing the external 12v supply by unplugging the alarm power cable (or if this is not accessible, by turning the caravan battery charger off and disconnecting the leisure battery).

Next open the base unit by removing the 2 screws on the top of the unit and then removing the cross bolt using a 10mm spanner. The black lid can now be lifted upwards and placed to one side. You will now see the backup battery mounted to an aluminium carrier plate.

Located on this plate is a small switch, which is the battery isolation switch. Turn this to the off (O) position.

Wait 15 seconds for the unit to reset.

Turn the battery switch back on (I position) and then reconnect the external 12v supply.

Replace the lid and fixings.
