!$ Skylink SC 1000 Complete Wireless Alarm System

I had an old ADT wired alarm system at my house. After a repeated number of false alarms, I decided to replace it.

I purchased a Skylink system. I used the existing wiring of the windows and doors (in series) in the lower floor of the house, attached to one sensor at the end. I replaced the 12V battery of the sensor with a transformer (output 12V 2 amp) so that I do not have to worry about the battery getting weak. I repeated the exact same thing with the top floor.

This way I can test each floor by opening just one of the windows (or doors) connected to that floor (or series) and use the test chime, instead of the actual alarm, to make sure that the circuit is closed. (The chime goes off when the closed circuit is interupted by opening the door or window, thus separating the contacts).

I used all the contacts available to me as needed.

I used transformers that usually come with hard disks, since I only use one or two at a time.

Drawbacks of the system.

1- The Keypad is not illuminated (minor).

2- The system forgets the assigned zoning occasionally, and you may have the alarm 'armed', but the sensors are not connected. So you have to check every now and then, to verify that the sensors are connected and not 'forgotten'

3- You can arm the system with an open circuit !!!!!!!!!!! There is no indicator on the keypad to verify the status of the zones. (My old alarm had a light indicating that the circuits are closed, in each zone before arming. The chime in this alarm will not sound with an open circuit, when you test it with the chime, but it will arm.

In spite of the fact that there are many things to consider, checking each zone in the alarm takes a few seconds, but an indicator light to rule out an open circuit in a zone, in the key pad would help a lot.

Checking the status of the alarm is very easy simple and quick for someone who understands how it works, but not for the lady of the house who was used to confirm the status by the indicators on the keypad, before leaving the house.
