Smart Alarm System

[1.52 lb] I have various alarm clocks in my lifetime and one thing annoying is how difficult it is to set an alarm and change it. This smart clock recognize my voice very well and now it is as easy as saying Wake me up tomorrow at 7 am to set the alarm.

[3.24 lb] Arrived swiftly, works as promised. Replacement power for home alarm system.

[5 x 5 x 1.5"] Excellent price. Timely delivery. We use them for the fire alarm system as back up power, and we never had any problems in the past.

[Beige] Product works as it said it would. We have a dog & a cat which have access through a 'doggy door' to the house when the alarm is on & we have not had the system go off with them going in & out the house.

I use this for a DIY alarm system in my house. I have 3 sensors connected to one base unit. The base unit is connected to a power source and an external 30w siren. The sensors detect motion...siren sounds. I turn power on and off via smart plug on my phone. Works like a charm. My only concern would be for the durability of the sensors. As can be imagined sensors are usually placed in high traffic areas which means activity happens all day long. If this will affect longevity of the product I do not know, only time will tell.

[16 VDC] Used for alarm system power supply. Auto resetting fuse and operating green LED is a great feature that was not on the Pittway.

[3.0 V] Those and the Duracell batteries are the only one you can use in sensitive wireless alarm system sensors. Worth paying extra rather than dealing with false alarms.

[8 Hours] Hello. We just had a power outage today, for 2.5 hours. As soon as the power went off this system kicked on automatically. I knew the power had gone out because this system has a beeping alarm when the unit is up and running. There is a button you can turn off the alarm. The alarm is not annoying - actually reassuring in a way - knowing that the system is up and running. The alarm turned off when the power was restored. All of my electronics quietly transffered back to the electric current in my house. My unit is now recharging again. I have 3 of these units in my house. I've owned them for a few years now. One unit for my internet system - which was up and running during the power outage. Sure I have internet usage on my cell phone, but all of my electronics that use wifi from my internet were also up and running as well - no interference or worrying about not having wifi available (unlike my neighbors). One unit hooked up to my Mac and Echo - both working throughout the power outage (still connected to the internet because my internet has one of these units). The last unit is hooked up to my TV (including Apple TV, a Roku Box, etc...). I've bought smaller units for smaller items that don't need as much power as this one provides. Overall I'm very happy with my purchase (B&H always delivers the best service) and these units have always come through during power outages. I'm looking to buy a few more... Thanks for reading my review. If you are looking for a great unit, you won't be disappointed.

[5 VAC, 1.5 A] We use this for a driveway alarm. We ordered the Optex Wireless 2000 Annunciator System and the first one, did not work out of the box, which was unfortunate. But the exchange process with B&H was extremely easy and conducted with the utmost professionalism. The 2nd system arrived and worked just fine. We replaced an older drive way alarm, that was obnoxious with respect to the alarm sound. We like the tone of this one and there are multiple sound levels, which is nice. We can increase the volume, if we are downstairs and turn it back down when upstairs.
