I need an instruction book for an M & J alarm that was already installed on our house, as I cannot find the original. I only need an instruction book for the control panel, or written instructions if someone knows. The keypad has number 0-9, A, B, *, and a musical note button. The control panel does not have a screen, but lights for power, day, pa, tamper and zones 1 - 8 (3 zones are installed).
