More about this product

About this product


This lock works in much the same way as the other alarm padlocks but it has a huge internal clearance allowing it to be fitted to gates and bikes easily. The shackle is a large 14mm steel bar surrounded by a protective plastic coating to prevent the gate or bike from being scratched.

Each lock comes with 3 keys that opperate the anti-pick cylinder barrel.

How The Alarm Works:
This model can be used with the alarm active or deactivated which is useful since they can be set off by strong wind or where it might be accidentally knocked. It should also be set to inactive when transporting.

Once activated the lock will become live within 15 seconds which gives you time to fit it to your gate, bike, or chain etc. The lock then has a fail safe movement sensor which detects movement within a 5 second period. For example 1 movement within 5 seconds will not activate the alarm. 2 or more movements within 5 seconds will then activate it. This prevents the alarm from being triggered accidentally by wind.

Setting The Lock - Alarm Active

1. Open the lock with the key
2. Remove the shackle and insert it into the body the oposite way
3. After you hear the "Beep" it is set
5. It is then active within 15 seconds

Setting The Lock - Alarm Inactive

1. Follow the proceedure above but when you insert the shackle into the body and no "beep" is heard then that is the inactive position, (opposite to the live position).

Are The Electronics Weatherproof?
Although the lock does use weatherproof electronics we would not recommend this lock for prolonged outdoor use for weeks where it is exposed to rain. If there is a cover or roof preventing the lock from getting wet then it ok to be used outdoors. Remember to ensure the lock is orientated upwards so that the alarm holes are not exposed directly to the rain. Please see the Xena models as a fully weatherproof alternative.

Can I Change The Batteries?
Each lock comes with batteries installed, although the batteries are readily available from your local supermarket. If the lock is not being regularly activated then you should see at least 1 year battery life from the lock but it is recommended to test it every 2-3 months anyhow.

Uses & Applications:
Even without the alarm these locks are good all round locks. However studies do show the alarm to be an effective deterrent. They are often used locked alone to items such as tools, tool boxes, steering wheels simply to warn someone that an item has been moved or tampered with.
