What is the successor to the MS112 Fire Lite 12 Volt 4 Zone System

Yes, it is the FireLite MS-4

Gee... Silent Knight has been a good successor for Frie Lite for me. (not a typo)

Heh, heh, heh. Many years ago we had problems with FireLite panels and stopped using them. About ten years ago we tried them again with better results.

Selling online I get orders for FireLite, Silent Knight, Ademco Honeywell and a few more. There haven't been any problems with FireLite lately.

BTW, we sell a fair number commercial fire alarms every month. Most of the time when end users buy a commercial fire alarm they employ a local electrician to do the installation. Larger companies have in-house electricians, some with experience on large-scale addressable systems.

When I started selling online I thought we'd only be catering to private individuals looking to save on the cost of installation plus those who don't want alarm monitoring services. It didn't even occur to me that we'd be selling commercial fire alarm systems.
