It is important to protect the SK-6324 control panel from water. To prevent water damage, the
following conditions should be AVOIDED when mounting the units:
• Do not mount directly on exterior walls, especially masonry walls (condensation)
• Do not mount directly on exterior walls below grade (condensation)
• Protect from plumbing leaks
• Protect from splash caused by sprinkler system inspection ports
• Do not mount in areas with humidity-generating equipment (such as dryers, production
machinery)

3.6 Mounting the SK-6324
Read the environmental specifications in Section 3.5 before mounting the cabinet.
The panel should be accessible to main drop wiring runs. It should be mounted as close to the
center of the building as possible and located within a secured area, but should be accessible
for testing and service. End-users responsible for maintaining the panel should be able to hear
alarms and troubles. When selecting a location, keep in mind that the panel itself is the main
source of alarm and trouble annunciation.
Mount the cabinet so it is firmly secured to the wall surface. When mounting the cabinet on
concrete, especially when moisture is expected, attach a piece of 3/4-inch plywood to the
concrete surface and then attach the cabinet to the plywood. Also mount any other modules to
the plywood.
Follow these steps to mount the control panel cabinet:
1. Place the cabinet on the mounting surface, level the cabinet and mark the top two mount-
ing holes.
2. Screw the top two mount screws about 3/4 of the way into the mounting surface.
3. Hang the control panel cabinet on the top mounting screws through the top mounting
screw keyholes.
Figure 3-2 Cabinet Mounting Holes
4. Insert the bottom two mounting screws into the cabinet’s bottom mounting holes.
5. Tighten all four mounting screws until the cabinet is properly secured.
6. Insert all cabinet components. See Section 3.7.

3.7 Assembly
The components listed in Table 3-1 are all packed with in the cabinet and require some
assembly. Follow these steps to assemble the components inside the cabinet:
1. Remove keys from small manila envelope taped to the top of the cabinet.
2. Unlock the cabinet door.
3. Remove the packing material and the SK-6324 components.
4. Snap the bezel into the opening in the front of the cabinet. See Figure 3-3.
Figure 3-3 Assembly Diagram for the SK-6324
Note: The bezel will fit in only one way.
5. With the two #8 Screws and the two #8 nuts (with built in washers), mount the transformer
in the holes in the upper left hand corner of the cabinet. See Figure 3-3.
6. With the three Self-trapping screws mount the control board on the cabinet stand-offs.
Note: See Section 4 for transformer connections and battery connections.

3.8 Wiring Specifications
Induced noise (transfer of electrical energy from one wire to another) can cause false alarms
or interfere with control panel operation in other ways.
To avoid induced noise, follow these guidelines:
• Isolate input wiring from high current output and power wiring. Do not pull one multi-
conductor cable for the entire panel. Instead, separate the wiring as follows:
High current input/output:AC power and notification device wiring
Low current input/output:Annunciator and zone loop wiring
• Do not pull wires from different groups through the same conduit. If you must run them
together, do so for as short a distance as possible or use shielded cable. Connect the shield
to circuit ground at the panel. You must route high and low voltages separately.
• Route the wiring within the cabinet around the perimeter of the cabinet. It should not cross
the printed circuit board where it could induce noise into the sensitive microelectronics or
pick up unwanted RF noise from the high speed circuits. See Figure 3-4 for an example.
• High frequency noise, such as that produced by the inductive reactance of a speaker or
bell, can also be reduced by running the wire through ferrite shield beads or by wrapping it
around a ferrite toroid.

3.9 Calculating Current Draw and Standby Battery
This section is for helping you determine the current draw and standby battery needs for your
installation.
3.9.1 Worksheet Requirements
The following steps must be taken when determining SK-6324 current draw and standby
battery requirements.
Filling in the Current Draw Worksheet, Table 3-6 (Section 3.9.3)
1. For the SK-6324, the worst case current draw is listed for the panel and is recorded in the
table at Line A.
2. Add up the current draw for all smoke detectors and record in the table at Line B.
3. Add up all notification appliance loads and record in the table at Line C.
4. Any additional devices should be recorded at Line D.
5. Make sure that the alarm current without the panel (Lines B-D) does not exceed 2.5 A.
The total alarm current (including the panel, Lines A-D) should not exceed 2.75 A.
6. Complete the remaining instructions in Table 3-6 for determining battery size require-
ments.
3.9.2 Maximum Battery Standby Load
Table 3-5 shows the maximum battery standby load for the SK-6324 based on 24 hours of
standby. The standby load calculations of line D in the Current Draw Calculation Worksheet
(Table 3-6) must be less than the number shown in Table 3-5 for the battery size used and
standby hours required.

3.9.3 Current Draw Worksheet
Use this worksheet to determine current requirements during alarm/battery standby operation.
(Copy this page if additional space is required.)
Note: If you are using door holders, you do not need to consider door holder current for alarm current because
power is removed during that time. However, during normal operation, door holders draw current and
must be included in the total standby current that can be drawn from the panel.
Note: Total standby current must not exceed maximum Battery standby load listed in Table 3-5.

4.2 Battery Connection
The SK-6324 battery charge capacity is 7.0 AH. Use two 12V batteries of the same AH rating.
Determine the correct AH rating as per your current load calculation (see Table 3-6).
Wire batteries in series to produce a 24-volt equivalent. Do not parallel batteries to increase
the AH rating.
Note: The SK-6324 cabinet supports two 7.0 AH batteries.
