Do you retailer your automobile or your instruments indoors? If that’s the case, you’ll need a dependable storage alarm to maintain them secure. On this evaluation, we’ll check to see whether or not Defender’s newest gadget is as much as the job.

We spend greater than we’d wish to admit on our vehicles. Whether or not or not it’s upgrades, upkeep, and even simply the instruments to get these jobs executed, this interest could make a fairly sizeable dent into your financial institution steadiness. With that in thoughts, putting in an honest storage alarm needs to be a no brainer for anybody who’s invested loads into their pleasure and pleasure. In any case, in the event you’re going to place the hassle into all different elements of automobile possession, why depart your self susceptible to thieves?

That, is the place Defender claims to have your again. Its new Shock/Contact Alarm arrives with a powerful set of accolades, together with the “Grasp Locksmith Affiliation’s Gold award” – a primary for this market phase, apparently. On high of that, Defender says that the alarm lives as much as the safety requirements recognised by the UK’s nationwide police forces.

Sounds good, proper? So how does it work? Effectively, with a billing like that, you’d be forgiven for assuming that there was some very complicated mechanisms underpinning all of it. Nevertheless, it’s truly quite simple to get your head round. Because the Shock/Contact identify suggests, the alarm is concentrated upon two sorts of unlawful entry. The ‘shock’ a part of the identify refers back to the alarm’s vibration sensor. So, in case your storage door is being pressured open by a heavy-handed thief, the alarm ought to choose up on this and sound because of this. However, burglars with a extra delicate contact will come unstuck just by breaching the alarm’s magnetic contact.


That’s the idea, anyway. So, we put the idea to the check…

The storage alarm and its accompanying magnet are positioned on both aspect of a double door entranceway, importantly solely 10mm aside.

Defender Shock Contact Storage Alarm Assessment


After inserting the equipped AAA batteries, we then set our private four-digit PIN code through the keypad – a course of which doesn’t require greater than a look on the instruction guide to know. With that executed, we moved onto set up, which we’re glad to report can also be a chunk of cake.

There’s a few methods you can go about doing it: particularly, by attaching the alarm’s again casing to the door with screws, or by sticking it to the door with the equipped 3M adhesive tape. We opted for the latter possibility.

You may marvel concerning the resilience of mere tape, however truly, we discovered it to be comfortably able to supporting the alarm’s weight over an prolonged time period.

Actually, there’s just one a part of the set up course of that requires any type of thought, and that’s the placement you select. To be clear, the alarm goes on the within of your storage door, and for the ‘contact’ a part of the system to work, you’ll want to make sure that the alarm and its accompanying magnet are not more than 10mm aside.

On this occasion, the workshop we had at our disposal was fitted with double doorways. So, in follow, this meant adhering the alarm to the sting of 1 door’s inside floor, then lining up the magnet in opposition to it on the adjoining door (pictured above).


Storage Alarm Check

Now for the loud bit. The primary ingredient of the alarm that we determined to place below scrutiny was the magnetic half. The thought behind it’s that when the door is opened, the space between the alarm and the magnet will enhance, thus breaking the magnetic contact. This successfully tells the alarm that the door has been opened, which then triggers a five-second countdown. Should you – or any unwitting thieves – fail to enter the PIN code in time, then the alarm might be triggered.

Now, it’s price mentioning that for this part of the check we disabled the alarm’s vibration sensor. This was one thing price doing because it ensured that the siren wouldn’t be activated by our contact as a substitute of a break within the magnetic contact space. Doing that is as simple as punching ‘111’ into the alarm’s keypad.

So, with the gadget armed, we braced our ears for what was to return subsequent. After a 30 second cool-down interval, we opened the door (triggering a foreboding beep) and shunned getting into the PIN code. As promised, the entire 130dB of alarm then sparked into life, signalling that it had handed the primary part of our check.

The vibration sensor was the place our focus would flip subsequent. We re-activated this ingredient of the alarm by typing ‘222’ into the keypad. Then, as soon as once more, we armed the gadget and closed the door behind us.

With the cool-down interval having passed by, we then did our greatest impression of a typical crim, yanking on the door deal with and throwing in a shoulder barge or two for good measure. Behind the door, that telling beep sounded as soon as once more, and positive sufficient, 5 seconds later the workshop erupted into noise.


On the finish of all that, it’s secure to say that this alarm does precisely what it says on the tin. Now, we’re off to go and apologise to the neighbours…

Defender Shock Contact Storage Alarm Verdict

Earlier than we go although, we couldn’t depart with out supplying you with our closing verdict. To place it merely, the Defender Shock/Contact alarm seems like nice worth for cash. Priced at simply £14.95, the gadget is simple to put in and as soon as armed does a commendable job of guarding in opposition to two several types of undesirable entry. After all, it will probably’t bodily stop robberies from going down, however we reckon you’d be exhausting pushed to discover a burglar that wouldn’t be scared off by 130 sudden decibels.

After all, there are some issues to think about although. For instance, in case your workshop or storage has further doorways or home windows, the localized nature of the Defender Shock/Contact alarm signifies that you’d want one per entranceway for complete peace of thoughts.
