SabreHS-DWA-UK Loud 120 dB Home Security Burglar Alarm | Easy DIY installation for windows or doors with siren, disarm or chime modes | 1 pack

Installed in minutes. Nice and loud with concealed on/off switch.These alarms aren't going to alert you via text message or to police etc...but I've put them on my patio door and back door.It makes me feel safe when in bed upstairs and even if I was out at least the loud news as soon as door opens then it would scare someone and alert neighbours.For the price you can't go wrong for just a bit of extra piece of mind if you can't afford all the bells and videos of other systems.

These are great - work exactly as you would like. I use them for a little extra security at night - if anyone opens the door it lets out a very loud chime. There are three modes, accessible via the battery cover at the front - chime, off and alarm. The chime is a loud doorbell-esq bing bong, whilst the alarm is piercing and continuous.They mount well, and are stuck on.Only improvement points would be a possible volume switch - it's very loud and sometimes you might want a more subtle noise, and it's also a very 'digital' noise, from a small speaker, so it's very intrusive. This is not necessarily a criticism, as that's kind of what you want in these alarms. Anyway, highly recommended.

Perfect extra bit of security for extra peace of mind. In the day I have my front door set just to the single chime and then can flick the switch on the night time to alarm mode which makes an ear piercing siren noise should the door be opened. Brought 2 others to be fitted to the back doors. Easy to install, discreet and well worth the money for extra peace of mind.

its o.k. does what it says, & the alarm is excellent, very loud, but no on/off switch accessible, with/if there was switch on side to turn off when you enter would make it 100% perfect. but for elderly, or anyone with problems, i.e shakes. not good.Mind we fitted on garage/shed door, we did buy another one with a on/off switch on the side, very good.

You have to make sure that the distance between the sound unit and the magnetic switch is very small. Sensitivity varies from unit to unit so check your switch is close enough before sticking in place. Adhesion is excellent but would be reduced if you have reposition. Definitely good value for money.

Does exactly what it says it does but the on and off switch is rather fidelity to use having to remove the battery cover every time that you want to switch on and off is a problem better if the switch was on the outside of the alarm

These are fine and loud enough my only issue is they are easy to switch off if someone broke in so have to be consealed a bit so they would take a while to find , they don’t stick to wood

Easy to fit, easy to use, very loud, but does the job we bought it for.

Works good

Funciona muy bien. Es el segundo par que compro. El anterior sigue funcionando y luego de 2 años se les acabó la batería. Las reemplacé y nuevamente como el primer día. El pegamento le ha durado y eso que estoy en zona de alta humedad y calor todo el año. 100% recomendado.

Ho messo questo articolo Sabre sulle porte blindate di casa con un unico scopo: sapere se di notte entra qualcuno. Impostabili su allarme o su "din don" effetto negozio, sono dotate di biadesivo extra forte di modo che sia facile per tutti appenderle ovunque.Attenzione, per attivare, disattivare o cambiare l'allarme è necessario rimuovere il coperchio che vedere sotto la sirena.

Der Fensteralarm ist sehr schnell montiert,und funktioniert auch einwandfrei.Einziges Manko man muß jedes mal die Abdeckkappe entfernen wenn man den Ein und Aus Schater betätigen will.

Funciona como promete, muy sencillo a instalar, alarma bastante alta a pesar de su tamano pequena. Tambien tiene modo timbre cuando abres la puerta.
