SINGCALL Remote Emergency Strobe Siren Alarm Kit Home Caring Alert System

I built a mother in law house about 80 feet from the main house and I was looking for something that could work that distance for medical emerdencys, In my case the buttons are throughout the back house and the siren is in the front main house, the furthest distance between button and siren is about 130 feet and I'm very happy to say it works perfectly and loud enough to here from any room even if you are sleeping or watching TV.

One of the buttons does not work I don’t know what to do. I changed the batteries in it and it still doesn’t work. The other ones do. Let me know what to do.

Nice product....this is the 2nd one I am buying....useful....loud enough...it has internal battery backup too. I recommend it

Works right out of the box. Very easy operation. No problems.

Just tried using the product and battery will not stay charged. 90 day return window is closed and product does not work.

work very well

Make these with built in solar on top so they can be put on outside of house and actually work. Put a back panel cover on these also so they mound better and protect against water. This would be good product if some common sense was added to the design.

Package rattled before opening. Open package and one unit rattled. Unscrewed unit and battery was loose. Loose batter knocked off diode or transistor off board. DAMAGED Still waiting for UPS to call for pickup. Advise.

And we needed loud. These sirens are easy to pair with the control buttons and easy to install. We are using them for an evacuation alarm in a large refrigerated warehouse where a hard-wired pull station system was impractical. We have linked 5 sirens and 7 call buttons to form a system that gives us full coverage of the building. The buttons are installed by the exits and any button push triggers all five sirens, even the one in the upper floor office space. The sirens are loud enough to be heard over the noise of refrigeration blowers, transport trailer noise and forklift traffic. This Singcall system has solved a problem I've been frustrated with for 25 years. Finally, I can retire with a clear conscience.

tutto ok

Product as described, installed and working "good for purpose". Thank you for this duress solution. - Phill.

Alarme qui fonctionne avec un branchement 220v(chargeur inclus) et sur batterie intégrée à l'alarme (l'alarme fonctionne sans le branchement 220v grâce aux batteries mais pendant combien de temps ?)Les télécommandes au nombre de quatre sont détectées à une bonne distance de l'alarme( minimum 15 mètres pour moi entre la télécommande et l'alarme ) l'alarme sonne fort et le réglage du temps de déclenchement de la sirene est simple à paramétrer( il faut ouvrir le boîtier de la sirene puis suivre la notice) pour l'instant je suis satisfait de mon achat

These are very loud sirens and great as panic button/ intrusion deterent.
