SECTION 4
MECHANICAL INSTALLATION
4.1
The KMSD smoke detector cabinet may be installed in either the CO2 room or the wheelhouse, at the owner's
option.
4.2
When the detector cabinet is in the CO2 room, a repeater cabinet must be installed in the wheelhouse.
4.3
When the detector cabinet is in the wheelhouse, a repeater cabinet should be installed in the CO2 room.
Operational provisions for dockside access to the wheelhouse will be necessary.
4.4
The suction blower cabinet may be installed anywhere convenient, within the limitations specified for the
interconnecting piping in Table 4-1 and the air flow diagrams. See Figures 4-1 and 4-2.
4.5
If the blower cabinet is installed in an outside location, the -flexible hoses must be painted or covered to prevent
deterioration from sunlight, etc.
4.6
With double blower cabinets (Figure 4-2), the slide valve in the slave cabinet (No. 2) is "locked" wide open; while
the slide valve in the master cabinet (No. 1) is adjusted for 1-3/4 1/4 inches of water with both blower cabinets
operating.
4.7
The suction blower must be installed upright so that the blower discharge flatter valves are in a closed position
when the blowers are turned off (see Figure 4-3).
4.8
The olfactory valve must be installed in the wheelhouse. It is recommended that this valve be installed at
approximately eye level.
4.9
A one-inch nominal I.D. outlet pipe is provided on the suction blower housing to supply the olfactory valve. Note
piping limitations in Table 4-1.
4.10
This pipe samples the air exhausted from the smoke detecting system, thereby permitting the detection of smoke
by smell and/or the verification of a smoke alarm signal.
