User questions & answers

Question:	can these be used to replace older non functioning window sensors
Answer:	When contact is made the circuit is closed. Normally open unless the door is shut, in other words.
Question:	can you use any magnet or only the one provided
Answer:	yes you can, make sure your glove box bulb doesn't exceed 10W otherwise use it with relay.
Question:	When the two pieces are together, is it considered no or nc
Answer:	No this device stands alone. This will talk directly with your Z Wave devices and can be controlled via web browser Great device.
Question:	How do these mount? I plan on using these in my glove box for lighting. Putting it on the grounded side
Answer:	I think you an install it yourself. I also had similar setup with vista 21ip. I simply disconnected the old console and connected TUXWIFI.

User questions & answers

Question:	I see it has a headphone jack. Can the wires be spliced and it'll emit load sound just by connecting it to battery terminal
Answer:	It's a loud " Continuos Chirping sound" at 120db very loud.will leave your ears ringing at close range.and in the interior of your car,it can drive you CRAZY!!
Question:	What is an affordable 12v battery that can produce enough power for the alarm to blast for 30-60 seconds
Answer:	I have not, but make sure your driver can handle the load. If it can you shouldn't have a problem.
Question:	What does it sound like? I'm looking for a loud siren for the interior of a car so I can add it to a car alarm
Answer:	Yes they can easily replace older non-functioning sensors, but the magnet piece that goes into the window is a bit deep and may not fit all windows. They would not fit my new Andersen Windows, but I was able to use small round magnets I bought from Home Depot together with the sensor piece that is recessed into the sill.
Question:	Has anyone connected multiple sirens together
Answer:	You can use earth or any strong (magnetic properties) magnet.

User questions & answers

Question:	Is there a light in this reed switch? The description mentions a light as does one of the reviews
Answer:	Not 100 percent, but probably less than 250mA. The housing is not rugged, it may hold up outdoors, but I would expect some rust. If you put it into an enclosure, or under an awning, it would be fine.
Question:	What size drill bit should i use for the window
Answer:	As is, it is volume is not adjustable.
