I have installed a DSC PC1555 hard wire alarm system with a PC 1575 LED keypad after checking all wiring and allowing the back battery to fully charge I tried to get the system to operate. The "trouble" light appears with zone light 1 on which indicates "Service Required" I would like to know what needs to be done to allow the system to operate properly. No other lights come on indicating all other systems are working properly. Any assistance would be greatly appreciated.
Thanks Mty Jerry
