2-2.1.1 SYSTEM NITROGEN CARTRIDGE, P/N 87-120043-001
The XV Control System uses a nitrogen cartridge for actuating the wet chemical cylinders and
is charged with dry nitrogen (see Figure 2-16). The cartridge is mounted inside the XV Control
System to protect it from tampering and provides the date of manufacturing and space (gray
band) for recording the installation date.

2-2.1.2 TEST CARTRIDGE, P/N 87-120044-001
The Test Cartridge is used for testing of the Kidde Wet Chemical System. The cartridge has a
red band and labeled "TEST CARTRIDGE" as shown in Figure 2-17.
Note: The System Nitrogen Cartridge P/N 87-120043-001 is required for actuation and full
discharge or "puff' tests.
The Test Cartridge (P/N 87-120044-001) must be removed and the System
A Nitrogen Cartridge (P/N 87-120043-001) must be installed at the completion of
CAUTION any work done on the system. Failure to do so will result in malfunction of the
system.

2-2.1.6 MICROSWITCH KIT, P/Ns 87-120039-001, 87-120039-501 (FOR XV)
The Microswitch Kit is a single pole, double -throw switch (see Figure 2-21 and Table 2-7).
Included in the kit is the microswitch, pigtail assembly and four mounting screws (two short
and two long).
Note; Microswitch Kit P/N 87-120039-501 includes a pigtail assembly with white stripes.
The wire leads are 24-inches (610 mm) in length. Four Microswitch Kits can be mounted in the
XV Control System. There are two mounting locations to accommodate the four Microswitch
kits (two stacked at each mounting location), with EMT ports for each mounting location. This
allows for the use of two electrical junction boxes for separation of signal lines and AC lines.
These are used when it is necessary to open or close electrical circuits. The following are
examples, but not limited to:
• Electric appliance shutdown
• Make up air shutdown
• Electric gas valve shutdown
• Shuntbreaker/relay
Note: Not for alarm initiation.
Electrical appliances usually have a higher amp rating than the switches. In this case, such
appliances shall not be wired directly to the microswitch. A magnetic contactor or relay must
be used.
For wiring the microswitch for XV, refer to Figure 4-30.

2-2.4.2 REMOTE MANUAL RELEASE PULL STATION, P/N 87-120110-001
The Remote Manual Release Pull Station, shown in Figure 2-35, is provided as a means of
manually actuating the system from a remote location. The Remote Manual Release is attached
to the XV Control System or the KRS-SO Control Box, with 1/16-inch control cable. The Remote
Manual Release Pull Station is available for use in both the "un-tensioned" Pull -to -Trip and
"tensioned" Release -to -Trip lines. To actuate the system at the Remote Manual Release Pull
Station, pull out the safety pin and pull hard on the handle.
In the Pull -to -Trip mode (XV ONLY), tension will be applied to the cable, allowing the XV Control
System to activate the Cylinder and Valve Assembly.
In the Release -to -Trip mode, removing the safety pin will release tension from the cable,
allowing the XV Control System or KRS-SO Control Box to activate the Cylinder and Valve
Assembly.
The Remote Manual Release Pull Station may be mounted in a recess or surface mount
configuration. The assembly is packaged with all necessary components needed to install in
either configuration. Mounting hardware is not included.
Each Remote Manual Release Pull Station is supplied with a choice of labels. The proper label
must be attached to the faceplate so as to be easily read after installation. Applying the label
after installation allows for vertical or horizontal mounting of the Remote Manual Release Pull
Station.

or a width of 4 ft. (1.2 m).
Plenums larger than 10 ft. (3.0 m) x 4 ft. (1.2 m) may be protected by adding additional ADP
nozzles for each additional 10 ft. (3.0 m) of plenum length and each additional 4ft. (1.2 m) of
plenum width. Nozzles may be installed pointing in the same direction, and/or at the ends of
the plenum pointing toward each other (see Figure 3-28). Each nozzle will provide coverage
for a maximum of 10 ft. (3 m) of plenum length and 4 ft. (1.2 m) of plenum width.
ADP nozzles must be centrally located in the plenum with their discharge directed along the
length of the plenum and located in relation to the filters as shown in Figure 3-28. Refer to
Figure 3-28 for filter height.

System Design
3-6.1.1 DUCTS
The ADP nozzle, P/N 87-120011-001, is used for protection of the exhaust ductwork.
The duct cross section can be any shape, not including obstructions (i.e., round, square, or
rectangular) and the duct itself can be of unlimited length. In accordance with NFPA 96, the
exhaust fan should be left running at the time of system discharge. This will help to remove
smoke and other airborne materials and gases from the hazard area in the event of a fire.
Check with the Authority Having Jurisdiction for local requirements. A damper, if present,
should be left open at system discharge. However, if the damper is closed, the system designer
must insure that additional nozzles are required.
3-6.1.1.1 Protection of Ducts 0 to 50 inches in Perimeter
One ADP nozzle, P/N 87-120011-001, is required for protection of a duct with a perimeter up
to 50-inches (refer to Figure 3-29). Length of duct is unlimited.
The nozzle is located at the geometric center of the cross -sectional area that it is protecting,
and is located in the duct within six inches of the entrance.
Note: All Kidde systems are listed by UL and ULC for use with the exhaust fan either on or off
when the system is discharged.

3-6.1.1.2 Ducts 50 to 100 inches in Perimeter
Two ADP nozzles, P/N 87-120011-001, pointing in the same direction are required for
protection of ducts with perimeters greater than 50 inches and less than or equal to 100 inches.
Ducts can be of unlimited length (refer to Figure 3-30).
For other option of ducts up to 75 perimeter inches (See Figure 3-32).

3-7 CYLINDER FLOWS
After finding how many nozzles of each type are required for a system, the sum of all the nozzle
flow numbers is used to determine the number and size of the cylinders required, in accordance
with the cylinder flow number limits given below.
