Hi all,

 

I have purchased and installed most of a Visonic system, the main panel being a Visonic PowerMax Express. I am looking to purchase batteries for the external sounder but am not sure which model number to use for the search as on the abs housing it is labeled as an MCS-740 and on the PCB it is labeled as an MCS-730. This is of course stupidity on my part but if someone could humour be I'd be very much obliged.

From memory there a big round one from a gasfire or pair with flying lead ?

 

 

poor security 1 way wireless, discontinued kit, not the most popular model of this old stuff either so not advised for fitting in 2026 at all...

MCS-740 is updated model of the 730. Red cap on the lid screw would be a K-305177

Thanks for your reply, I've ordered the batteries. Thank you for your opinion on the system too, I got the panel and 2 PIRs free. I am on a tight budget and between something like a Micromark shed alarm this was the better option 😀.

Hopefully you have the Y splitter cable that comes with the siren or you can't plug them in.

Thanks for that too! I don't have it (Siren was second hand off eBay) but looking at the batteries I ordered the splitter is included. 

 

What's the standard now in wireless alarms, Texecom or the likes? I hate those new ones by verisure and eufy etc. 

Verisure, Eufy, Ring all junk.

Texecom is what I fit but not supported for end user installation.

Maybe Scantronic?
