Amerex Restaurant Fire Suppression System (EX 4658)
INSTALLING THE MECHANICAL RELEASE MODULE (MRM):
Select a suitable location for the mechanical release module that has access for installation, service, recharge
and where both the nitrogen actuation cylinder pressure gauge and the system status indicator can be
viewed. The MRM must be fastened to a surface that has sufficient structure to support the loads anticipated.
Knockouts are provided on three sides of the two available enclosures (painted or stainless steel) and each
cable run may enter the enclosure from any of the three sides (top, bottom or right).
Using the enclosure as a template, mark the top two holes for mounting and anchor the enclosure loosely,
adjust to level and mark bottom holes, anchor loosely using appropriate fasteners.
Once the enclosure is loosely attached to the mounting surface the MRM plate can be installed into the
enclosure stand offs using the four machine screws provided with the MRM.
Do not install nitrogen
actuation cylinder at this time or system may accidentally actuate.
After the MRM plate is installed
tighten fasteners anchoring the MRM enclosure to the wall.
