3.6
Mounting the SK-4224
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
mounting 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.

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 cabinets 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-4224 components.
4. Snap the bezel into the opening in the front of the cabinet. See Figure 3-3.

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 multiconductor 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.

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-4224 current draw and standby
battery requirements.
Filling in the Current Draw Worksheet, Table 3-6 (Section 3.9.3)
1. For the SK-4224, 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 2 for determining battery size requirements.
3.9.2
Maximum Battery Standby Load
Table 3-5 shows the maximum battery standby load for the SK-4224 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.

SK-2880 Installation
The SK-2880 is an Input/Output module. The SK-2880 has 33 pre-defined open collector
outputs (see Table 4-6) that can be used to drive LEDs, interface with other controls or
systems, or control one of the three built-in Form C relays. See Figure 4-13, Figure 4-15 and
Figure 4-16.
The SK-2880 also has two supervised inputs used for Reset and Silence. See Figure 4-16.

Follow these steps to mount the SK-2880:
1. Remove the SK-2880’s cover. A small screw driver can be used.
2. Remove the SK-2880 circuit board from the base by pushing outward on the base retaining tabs and lift the circuit board out. See Figure 4-17.

Notification Expansion Mode
The SK-4224 can be used to expand the power capabilities of an existing system’s notification
circuits. The SK-4224 does this buy connecting the notification circuits of an existing or host
fire alarm control panel to the FACP input of the SK-4224, which can trigger the SK-4224
notification cicuits when the host panel goes into alarm.
Note: The SK-4224 does not go into the alarm state when the host control panel triggers the SK-4224’s
notification cicuits.
5.1
Class A Notification Expansion Wiring
Figure 5-1 shows Class supervised wiring from a host panel to the SK-4224 control board.
Observe the proper polarity when making wire connections and follow these requirements:
•
When wiring to terminal B on the SK-4224, you must use two separate wires. Do not loop
a single wire or twist two conductors together.
•
FACP input 20.4 VDC to 26.4 VDC.
•
Do not use notification appliances on Class A circuits connected to the SK-4224 FACP
input. The SK-4224 will detect voltage across the input circuits, but is not designed to pass
the added current load from the notification appliances.

Class B Notification Expansion Wiring
Figure 5-2 shows Class B supervised wiring from a host fire alarm control panel to the SK4224 control panel. Use an EOL resistor as shown in to supervise the FACP input. The host
fire alarm control panel may use an EOL with a value other than 4.7 KΩ, used by the SK4224. In this case, use an UL listed EOL for the host panel you are using.

System Configuration
To configure the SK-4224 system set the dipswitch that controls the option you want to
select. The following chart shows how to program the dipswitches that control system, zone,
and notification appliance operation. Refer to Figure 3-1 for location of the dipswitches.
Important!
When you change a dipswitch, be sure to perform a system reset (press [RESET]) or power
down the panel. Dipswitch changes will have no effect until after the system has been reset.

System Operation
The annunciator on the SK-4224 board is used for all system operation. It contains the

In walk test when a detector is tripped it
will cause an alarm for two seconds, then
the control panel will drop power to the
loop for seven seconds to reset the
detector. Then an additional 38 seconds is
needed to restore the detector.
If verification is used the time between

This section of the manual contains information about smoke detectors that are compatible
with the SK-4224.
SK-4224
Identifier
Voltage Range
24F
16.2-27.3 VDC
Note: The maximum number of smoke detectors per zone is determined by both the current draw and the impedance of the smoke detector. If too many smoke detectors are used on any zone, false alarms could occur.
Do not mix different models of detectors on any zone; false alarms could occur.
A.1.1 Enhanced Mode
Enhanced mode allows the installer to use pull stations on a loop that has been programmed
for Enhanced Alarm Verification. If a single detector goes into alarm it will start the alarm
verification cycle. If a pull station is activated any time during the alarm verification cycle and
after the control panel re-applies loop power (power will drop for seven seconds to restore
detector during verification), the panel will go into immediate alarm and discontinue the
verification cycle.
Warning! Do not mix different models or manufacturers of smoke detectors on the input loops.
