Post by: hammer1 on December 11, 2009, 02:40:04 PM

which is too NFPA standard 72 A-D.

Can anyone enlighten me on this type of fire alarm system. Seems it was installed before 1000BC.

If it looks very old and big it could be one of ADT’s first attempts at an addressable panel. I recall correctly they were called uimode made in the US so that explains the NFPA standard.
