Questions & Answers
There is no mute button on the alarm itself. Mine has a power switch that allows me to turn it off.
The wire is clamped under a screw head / square washer by the terminal, which prevents the live wire from being exposed. It can handle a variety of wire diameters. In my case, I'm using 14 gauge stranded, but anything from 12 to 16 gauge would work. It should work with 24 gauge stranded or solid wire. br>br>The buzzer is bright and loud, and it gets the job done. Mine serves as a freezer overheat alarm, which it does admirably.
You can leave it out in the elements as long as it's on its side with a small shield above it to protect it from direct rain or being slashed by water. The alarm sound is emitted through small holes in the red lens. Mine has no NEMA rating, so I'm guessing it's only nema 1 and not nema 4, which would make it completely weatherproof. So it's fine to be outside as long as it's not in direct contact with water.
It is equipped with two wire connections. Simply cut the wire from an extra power cord (for a computer, laptop, or anything else with a regular 2 prong AC outlet fitting), strip the wire, connect the wire to the two leads on this alarm, and plug the other end of the wire into the outlet. The alarm will not go off unless the outlet is turned on or, in your case, when the timer is set.

When you need to figure out which circuit the breaker is on in your home, this little gem comes in handy. All you need is a short power cord with a plug attached, which you can plug into any outlet and wait for the buzzer to stop as you flip the circuit breakers. Simple and inexpensive. br>The only minor flaw I discovered is that the plug wiring enters on the side of the rear case rather than the back. To be safe, I wrapped the wire insulation and case in heat shrink. As an alternative, electrical tape would suffice.
It's a security system. It makes a buzzing sound and flashes. It's loud enough to grab your attention, but not so loud that you lose your hearing.
This is exactly what I needed to make a "utility power is back" alarm for when we lose power and have to rely on the generator. It was exactly what I was looking for. The alarm beeps loudly enough to be heard throughout the house, and it also features a red flashing light. The wires were connected using screw terminals, which made it simple to connect: simply strip the wires, insert the screws, and tighten them.
Very good value for money.
It can also be used as a test device. With the addition of a power cord, the test device can now be used for electrical work. You can plug into an outlet and walk to the circuit panel, where you can try breaker after breaker until the noise stops. I'm sure it's just as good for what it's supposed to be used for!.
When activated, the light turns on and a siren sounds. It performs exactly as it should.
It appears to be doing a good job of keeping starlings away from our bird feeders.
As stated in the advertisement.
