Scantronic 9448+ and 9427 control panel help please

Hi, We had a power cut with the strong winds last week. Since then my alarm has stopped working.

When I turned the power on the main unit internal buzzer was sounding so i flipped the fuse for the alarm system.

Now when I turn the power on to the alarm there is no power light on the main unit or keypad but the keypad is illuminated. I have a new battery for it.


Any ideas.

First step would be totally power down inc battery , wait 30 secs and power up mains ,alarm should go off on power up, if your code does not stop it enter 1234 if this now stops it , you may have to reprogram the system

Hi. Thanks for reply.

When I flip the mains fuse for alarm nothing happens. The backlight on the keypad lights up and makes tone when keys are pressed. Also the motion sensors in the house flash red when movement is detected.

As above power down INC BATTERY ....

I removed the battery and powered down. I will power up tomorrow as it's late now do not want to disturb neighbours .

When I power up will I connect the battery first or just power up without battery.

Last time I powered up without battery only key pad lit up no power light on main unit or key pad though.

Mains first

Hi. Replaced one of the fuses on pcb as it was blown. Turn the power on with no battery connected and the power light does not illuminate on main unit or key Pad. The keypad lights up and the interior motion sensors are working?. There is a tone when keys are pressed on keypad but nothing happens.

Have you tried 1234 ? You may have to put it in twice ...
