what are the little metal buttons on the door/window sensors? Are they extendable antennas? Do they pull-out to get longer?

Yes, the buttons are the tip of an extendable antenna. Latch on with finger nails and pull out.
1459184
Yes, They pull out if a stronger signal is needed. Personally I left all mine down and they worked fine.

No extensions for this that I'm aware of. This is just a guess, but there might be similar products that use radio frequency.

Yes. The sensor is tethered to the unit I don't recall the exact length, but the probe is in one room and the actual gauge is outside, I get readings with out opening door. Works fine for my needs.

The window sensors only work when someone tries to open the window. Some systems also have 'glass breaker' detectors if someone tries to break the glass, but I don't like those as any vibration can cause them to trigger.

By default, all the door/window contacts are in Zone 1 and the motion detectors in Zone 2. When armed Away, all contacts and sensors will work. When armed Home, the detectors in Zone 2 will not work. Good feature.

the sensors that is attached to the door cannot be turned off because once you remove the guard strip its always sensing. You can only turn off the base unit from inside the house in which if you have more than one sensor which is maximum of four sensor, all of them will be off. Unless you reprogram it from the base unit but in my opinion is such a hassle to reprogram.

The windows/door sensors are close/open switch and its aren't vibration/breaking type. Its wireless range is very good. Programming additional sensors over the includes in the OFFER is not easy task. The price is good but for additional $50.00 you can buy a more heavy duty system.

Yes, very easy installation same as your door/window sensors. Follow instructions with your system manual if unsure. Then call your security monitoring company to confirm addition.

I have installed two of these systems in the past two years, one at my brother's house and one at his place of business. The business is a large shop and the office on the second floor is a distance away from the entry door. We have infared sensors and door sensors. I installed another at his house and we have 3 infared sensors and two door sensors and a remote external alarm and are all quite far away from the control. Everything seems to be running okay for now. Good luck!

The antenna is flexible and can be bent over a little to avoid the door. It should still operate normally.

With no obstructions, about 30- 40ft. Make sure you have the transmitter and door magnet sensor touching each other.

No the antenna is at a fixed length and does not extend. The only thing that really does help for better reception is placing the unit by a window. A connection is made with a cord that plugs into the phone and then plugs into the unit. This unit is for older styles of phones whether they are cordless phones or not. The antenna is for reception from the base to the cell tower.

Hi Jean D..This is Dave from Pa. I recently ordered one of these units for my emergency response vehicle, no honey, the antenna is on there permanently, it's just a wire wrapped around a fiberglass stick, if u will, but not removeable, hope that helped, Amazon's computer asked that I answer your ? for ya.

I attached the magnet end of the antenna to the top of my window blind (which is metal). In all the time I've had the antenna, it has only fallen once when someone accidentally tugged on it while moving the curtain. It has been a miracle for my household. We went from 0 bars to 5 bars as soon as the microcell found the signal (it only took a few minutes).

They come with the two sided stickers and these have external antenna. The sensors I got in the kit had internal only antennas (Fortress Security Store (TM) GSM-B Wireless Cellular GSM Home Security Alarm System Auto Dial System : DIY Kit )

There is a little play. But I have it mounted up high on a window and I can't tell if there is a set screw. As with all window antennas "you get what you get". But I get better performance than just sticking an antenna by the window. Maybe you could use an antenna tuner between your antenna and your CB to tune it.

There were 7 door/window sensors included in the package, as well as 3 motion sensors, the control panel, a remote keypad, and two wireless key fobs. I added two smoke detectors and a remote siren from Sears' online site; the order was fulfilled by Shield Tech. When the remote siren malfunctioned on installation, I contacted Shield Tech support directly and they promptly replaced the device. My system functions armed for weeks at a time and has had no false alarms, while tests of the various devices that I performed have always proved reliable, including notification. I will probably add several more motion sensors vice installing all my door/window sensors--primarily because they cover areas within my home versus specific doors and windows. I think you have to look at probable access points and how the property might be entered and make a judgment as to the type of sensor and, by the way, how the sensor is configured (for example, delayed alarm versus instant). Hope this helps.
