Just want some public opinion as I am thinking about adding the MS-4 to my collection. I like the MS-5UD way better, but it is a bit out of my price range.
By the way, this is the ugliest picture I have ever seen of an MS-4 
No. Do not buy one of these panels. They are essentially the worst brand new panel produced, and you’re just wasting your money purchasing one.
They have many issues, including (but not limited to):
- FWR NAC/AUX outputs (can damage devices not rated)
- Limited capabilities & programming
- Poor build quality (cabinet quality sucks)
- Prone to random failure in multiple areas, including:
– Relays
– Main master controller board
– Power supply
So…don’t buy one. Save up some money, and buy a good conventional panel like the Simplex 4004 or MS-5UD.
Alrighty, thank you so much for the advice. I don’t have many friends that are interested in fire alarms so this helped!
