Upon the completion of the steps in this article, you will be able to call the guard unit from a 4+N skyline button panel. Calling a guard unit is a familiar situation in garages, hospitals where the guard unit has to be called just by pressing one button.
It is already known by you how to connect the 4+n panels: City Classic & City with continuous profile and integrated push buttons, to the panel decoder reference 2436. We will see now the connection of the skyline panel which is different from the mentioned ones because we have to deliver a negative instead of the “Cp” signal, via the external button module.
See below the schematic of the modification that we have to make in order to support calls to a guard unit from a skyline button panel:
The purpose of these operations is to send a negative “3” to the ”C” of the Panel decoder (2436) instead of the “Cp” signal that would be sent when you perform a standard 4+n installation.
The steps you that you have to follow to achieve this:
Cut the wire that corresponds to the 3rd pin of the amplifier connector (blue wire) of the 3 wires that connect the amplifier to the button module as seen in the picture:
Connect the terminal that lacks the blue wire to the amplifier connector (the 3rd pin remains free) and the other to the push button module while having the end of the blue wire inside terminal “3” of amplifier as such:
In order to have confirmation tone in the panel when the button is pressed, the “Cp” has to be connected to the same button module, to be joined to “3” through the button (via the blue wire).
Connect the terminal of the push button to Cp1 to hear the confirmation tone in the panel when the button is pressed.
Since the module above is being used to send a negative (by connecting the “3” and the “C”), then we need another module to call a terminal which will be used to connect “4” and “Cp” to send a square wave pulse train to ring the bell inside the telephone.
See below the schematic of the modification that we have to make in order to support calls to a guard unit and a telephone from a skyline button panel:
Following steps to connect a Skyline 4+N panel with pushbutton module to a terminal:
Cut the cable of first pin at button module connector (blue wire) of the 3 wires that connect the output of the upper push button module to the input of the lower module.
Connect the blue wire to either “Cp1” or “Cp2” signals, according to the tone that you want to hear from the terminal (in orange circles)
Connect the terminal of the push button to that of the terminal 4 of the handset so that when the push button is pressed, the Cp (either 1 or 2) is connected to 4 and the ring-tone is heard at the handset.
Connect the terminals 1, 2, 3 and 6 of the handset to the panel amplifier as you would do in a regular 4+n connection.
