johnnyd Posted April 23, 2012 Share Posted April 23, 2012 Hi All I have just fitted a powermax pro and want to use the existing wired bell My existing system has a 6 core going to the ext bell box and all 6 wires are used Black is 0v. Red is 12v. blue is Bell sw. white is Strobe sw. green is tamper F and yellow is tamper R. I have the first 4 connections made and the siren and srobes work, but its the tamper i am unsure about Does anyone know how i connect this to the powermax pro ?

sixwheeledbeast Posted April 23, 2012 Share Posted April 23, 2012 You have to use a hardwired zone on the panel. The tamper has to have the EOL resistor across it.

sixwheeledbeast Posted May 7, 2012 Share Posted May 7, 2012 Tamper Feed will be linked to Neg normally done in bell. Tamper Return will have a resistor in series with the one tamper wire in the panel zone.
