Review: Great little device - It's ruddy loud, and strobe is blindingly fitted to a number of items in the garden should anyone trying getting them under the cover of darkness. Would certainly recommend Review: Wow, it’s Loud! - Works straight out of the box. The battery is already installed, so no setting up. Pull the little pin out of the alarm and a 140dbs wave of ear splitting noise booms out. The pin won’t come out until you pull on it with a small bit of force, so it won’t go off in your car/bag/pocket. It has a little torch built into it, bit like a key torch. It can also be mounted on a wall/door. Just a bit of a warning, cover the alarm with your hand when you test it or wear earplugs because it’s very loud. I would recommend 👍 ## Features - UK’S LOUDEST PERSONAL ALARM - Features a hugely powerful 143dB siren, when activated using the ripcord, the unit releases a high-intensity strobe light, alerting those around. - DEFENDER IIIT PERSONAL ATTACK ALARM - Designed to deter a potential assailant and attract the attention of bystanders.

It is powered with a PP9 type battery but a PP9 one will not fit!! The connection will not mate up to the terminal posts!! The only way to use the alarm is to find a PP9 connecting wire from an old piece of equipment then after removing the original one solder this one in it's place. I could not find anyone who sold the original battery. Hope this helps. Maurice **Q: What does 'police preferred' mean exactly? Name a police force please so that I can be reassured.** A: May I suggest you ask the seller or manufacturer to identify the forces that they claim prefer the item. Or ring your local nick and ask to speak with their Crime Prevention officers. **Q: Can you offer more details about what battery can be used since I see an usual 9v battery is not compatible.I always use Duracell plus , compatible ??** A: Normal 9V battery in both mine.
