Guest ktd Posted April 14, 2004 Share Posted April 14, 2004 Hello, I am a first timer on your site and seeking your advice and expertise. I have a Scantronic 9448 alarm panel which was installed in 1990. It has been faultless until i went to set it last night and could smell something. The bottom and centre of the panel were hot. I deactivated the system and opened the panel to find the battery and transformer very hot. Does anyone know the cause of this and the solution Any advice and guidance would be appreciated. Kind regards Kevin Link to comment https://www.thesecurityinstaller.co.uk/community/topic/1950-scantronic-9448/ Share on other sites More sharing options...
Service Engineer Posted April 14, 2004 Share Posted April 14, 2004 Sounds like the backup battery has had it, become very low resistance and is starting to overload the charging circuit, i`d remove the battery and replace it ASAP. And then hope it hasnt caused any permanant damage to the charging circuitry. ........................................................

Service Engineer Posted April 14, 2004 Share Posted April 14, 2004 Is there a date on your existing battery..? the installer should have written the installation date on it, just wondering because they should be replaced every 4 or 5 years. ........................................................

Guest ktd Posted April 14, 2004 Share Posted April 14, 2004 Dave, There is no date on the battery but I know it is as old as the installation. (14 years). I now know it is well overdue for replacement Link to comment https://www.thesecurityinstaller.co.uk/community/topic/1950-scantronic-9448/#findComment-10834 Share on other sites More sharing options...
Service Engineer Posted April 14, 2004 Share Posted April 14, 2004 The control panel battery is so often overlooked by many users, they are usually fine for 4 or 5 years, sometimes slightly longer. Then they start to deteriorate, some like yours develop a lowered resistance and cause the panel power supply to overload, some Explode, some start to leak battery acid in the panel and that can cause all sorts of problems. Hopefully yours will be fine, as you seem to have noticed it fairly quickly, but if you have a Voltage meter just check the voltage at the battery terminals is about 13.2/13.8 Volts before connecting the new battery. ........................................................

Guest ktd Posted April 15, 2004 Share Posted April 15, 2004 Hello Dave, Replaced battery last night and pleased to say everything is working fine. I have marked on the battery the date of installation so the same thing doesn't happen again Thanks for your help.

Service Engineer Posted April 15, 2004 Share Posted April 15, 2004 Glad that everything is still ok Kevin, but please consider getting the system serviced just to put your and my mind at rest that everything is ok. Appearances are often deceiving. ........................................................
