General
These instructions apply to the MRI-2000 4" standard base and the MRI-2001 6" E-Z Fit
base.
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. Secutron 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 accordance with the re 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 com-
pound (or equivalent) to seal eld wiring conduit opening in the electrical box, this will
reduce the stack 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 tted. Connect the shield, if required, to the SHIELD
terminal on the base. For information on how to set the address of each device correctly
refer to the section 'Address Setting' overleaf.
