Not fitted an alarm for years so, i have started an installation with the ADE ACCENTA 8 zone panel, using medusa PIR's, all of which i have used before without any probs.................but this time i have got a KINETIC AZ-TECH bellbox..........recomended by the wholesaler. Does anyone have any experiences of this bell and also..............i can remember when fitting the old NOVAGARD boxes to the ADE panels . the NOVAGARD needed a link wire, from one terminal to another. Obviousley i have the instructions from the AZ-TECH for the standard connections, but is there still a need for the link wire. And if anyone can remember the link wire im on about, It will also save me climbing up to look at my 10 year old NOVAGARD on my house
