james.wilson Posted April 23, 2019 Share Posted April 23, 2019 Ni cads can take a lot of abuse when I used to race model cars you could put more into them than so called fast charging today. Used to thermal charge at a stupid temp limit. Used to put the thermocouple on the pack. Ni mh was a good compromise of capacity etc but I'd go nicad on a bell if I wanted to design one securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.

Gabs Posted April 23, 2019 Author Share Posted April 23, 2019 Yeah, I have a 6v one, stolen from the PCB of my dead hexagon Modern Alarms bell box, was happy for me to put in 12v all day, drew no current, didn't get hot and it held a charge fine, probably how most SABs do the charging, constantly cutting power into the battery, through the Hold-Off Voltage Link to comment https://www.thesecurityinstaller.co.uk/community/topic/42729-start-an-alarm-manufacturer/page/9/#findComment-483932 Share on other sites More sharing options...

The IC is Philips, not seen that before.

Funny how Honeywell own them, yet the newest Accentas still say ADE on them. I would be interested to get my oscilloscope on that Avanti and compare the serial data to an Accentas. I bet they would be the same or similar. So, GSPK make the boards, I wonder if they are also involved in the circuit design? Or thaw as done by whoever previously worked at ADE and left when they were sold?
