MIR-65 Series Smoke & Heat Detectors
Installation Instructions
General
These ins tructions apply to the 6” E-Z Fit base, part no MSB -65B, for installing
MIR-65 Series smoke and heat detectors.
Installation
These pr oducts must be installed in accor dance with the applicable NFPA standards,
local codes and jurisdictional authorities. Failure to follow these instructions
may result in failure of the detectors to report an alarm condition. Mircom is not
responsible for dete ctors which are improperly installed, maintained and teste d.
Before in stalling the se produc ts chec k the continuity, polarity and insulation
resist ance of all wiring. Check that siting is in accor dance with the r e system
drawings and conforms to all applicable loc al codes such as NFPA 72.
Use 3” oct agonal box for dir ect connection to the base. 4” oct agonal and 4” square
boxes may be used with proper UL listed mounting brackets. When mounting on
a wall, install 4” to 12” from the ceiling. Use 3M Weatherban 606 Non-Flammable
sealing compound (or equivalent) to seal eld wiring conduit opening in the ele ctric al
box, this will reduce the stac king effect. Secure the bas e to the elec trical box with
appropriate screws. Do not overtighten the screws. The raise d mark on the side of
the base indic ates the direction of the detector LED when t ted. Connec t the shield, if
required, to the SHIELD terminal on the base.
