2-2 CONTROLS
2-2.1 UNIVERSAL CONTROL HEAD (UCH) ontrol System, P/N B 120099
- The UCH Control System, P/N B120099, is used for actuating the Range Guard Cylinder and Valve
Assembly. The UCH Control System can be attached to the System Valve Actuator, P/N B 120042 for
direct cylinder mounting,or to a wall for remote mounting. Knockouts are provided to accommodate
either type of mounting. The controller can be operated with:
• Automatic mechanical detection (fusible-links and thermo-bulb links),
• Automatic electrical operation, and
• Remote and local manual operation. ,,

3-8 PIPING REQUIREMENTS
Range Guard systems do not require balanced piping to achieve proper distribution of wet chemical
to all nozzles. Balanced piping is not necessary because a liquid has no difficulty in turning corners
or changing directions.Range Guard nozzles come equipped with permanent predetermined orifices.
This means that the liquid will be delivered in the exact quantities necessary to the duct,plenum and
appliance hazards as required.
All pipe shall be schedule 40 (standard weight)black steel. Pipe may be chrome plated. Galvanized
pipe shall not be used.All pipe and fittings must be made tight without pipe dope or thread sealant.
Pipe fittings shall be standard weight steel, cast iron, malleable iron or ductile iron. Galvanized
fittings shall not be used. Branch line connection and individual nozzle connections may be made by
using either the outlet or the run of a tee.
3-8.1 Stainless Steel Tubing and Fittings
Stainless steel tubing may be used on all Range Guard systems. Fittings may be stainless steel
compression or stainless steel flare types. Bending of tubing using mandrels is permissible.
3-8.2 Pipe Sizing
Pipe sizes are determined by the total number of flow numbers running through a particular piece of
pipe. This is the flow demand for that portion of the system.
Note: It is not permissible to drop pipe diameters below the required value.For example,using 1/2-
inch pipe to flow 18 flow numbers is not permissible. However, increasing pipe diameter is
acceptable (i.e., using 1-inch pipe to flow 18 flow numbers) providing the system complies
with internal pipe volume limitations.
Table 3-31. Flow Number Range and Pipe Type
Flow Number Range Minimum Pipe Size .035 Wall Stainless Steel Tubing Size
1 —2 1/4-inch 3/8-inch
1 —8 3/8-inch N/A
1— 12 1/2-inch 5/8-inch
13—24 3/4-inch 7/8-inch
25—48 1-inch 1-inch
3-8.3 General Rules
• A maximum of 100 equivalent ft. (30.5 m)but not more than 40 linear ft. (12.2 m)of 1/4-in.pipe
may be used from each branch line.
• The highest point of the system shall not exceed 12 ft. (3.7 m) above the cylinder outlet.
• The vertical rise of a branch line above the supply line shall not exceed a maximum of 4 ft.
(1.2 m).
• Maximum discharge pipe volume limitations shall not be exceeded.
• Maximum equivalent length limitations shall not be exceeded.
• Maximum flow points for a given pipe shall not be exceeded.
• There are to be no low points or "traps"present in discharge piping.

System Design
3-8.4 Discharge Line Volume Limitations
There is a discharge line volume limitation in Range Guard systems. Discharge line volume is the
total volume of all pipe, tubing, and fittings used in single or multiple cylinder systems.
To measure discharge line volume, it is necessary to measure all pipe length from the center of one
fitting to the center of the next fitting and multiply by the volume-per-foot factor given in Table 3-32
and Table 3-33.
Table 3-32. Piping Discharge Line Volume
Size Piping Discharge Line Volume
1/4 in. 1.25 in.3 per linear foot-(67.2 cm3 per linear meter)
3/8 in. 2.29 in.3 per linear foot-(123.1 cm3 per linear meter)
1/2 in. 3.65 in.3 per linear foot-(196.2 cm3 per linear meter)
3/4 in. 6.40 in.3 per linear foot-(344.1 cm3 per linear meter)

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.
To wire the microswitch for UCH, refer to Figure 4-30.
