I have a scantronic 9448 alarm. Power went off one night and alarm would not switch off, key pad unreponsive. Carried out factory reset and although I have manual cant seem to reproramme it properly., basically dont know what I am doing. I live in a bungalow and have 5 pir detectors, one in hall, and kitchen where both exit doors are, one in living room, bedroom and second sitting room. The external alarm and light is not working however when i check them using keypad 4 code they are working. I assume alarm is not properly programmed. Any advice please ??
