MIR-65 Series Smoke & Heat Detectors
General
These instructions apply to the 6" E-Z Fit base, part no MSB-65B, for installing
MIR-65 Series smoke and heat detectors.
Installation
These products must be installed in accordance 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 detectors which are improperly installed, maintained and tested.
Before installing these products check the continuity, polarity and insulation
resistance of all wiring. Check that siting is in accordance with the fire system
drawings and conforms to all applicable local codes such as NFPA 72.
Use 3" octagonal box for direct connection to the base. 4" octagonal 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 field wiring conduit opening in the electrical
box, this will reduce the stacking effect. Secure the base to the electrical box with
appropriate screws. Do not overtighten the screws. The raised mark on the side of
the base indicates the direction of the detector LED when fitted. Connect the shield, if
required, to the SHIELD terminal on the base.
