1. GENERAL INFORMATION
1.1.System Purpose. The UNITED Fire Systems STANDPIPE-PAC™ Model SSS-101 Standpipe Supervisory
System is a fully assembled standpipe supervisory system, including compressor, switches, alarm, and control
unit providing one complete zone of standpipe supervision in compliance with Boston FD TCM3-51725. All
components are mounted on a sturdy wooden backboard, suitable for hanging at a construction or demolition site.
1.2. Boston FD TCM3-51725
Boston FD TCM3-51725 was implemented in response to serious difficulties encountered when fire standpipes at
construction and demolition sites were damaged, rendering the standpipes unsuitable for fire department use.
The directive requires that all fire standpipes in vacant buildings, buildings undergoing demolition, and required
permanent or temporary standpipes in buildings under construction be equipped with a system to pressurize the
standpipe at all times, which then would sense the pressure loss if a portion of the standpipe was damaged or
completely removed. Detailed requirements for the system are specified in the directive. STANDPIPE-PAC™
has been designed to aid in compliance with the requirements in Boston FD TCM3-51725. IMPORTANT:
Boston FD TCM3-51725 requires that an application to install an air pressurized alarm system be filed by a
registered design professional, and a permit obtained by a licensed sprinkler contractor. A licensed electrician
shall obtain all required electrical permits. Install STANDPIPE-PAC™ after application is made and accepted,
and all permits received. To review Boston FD TCM3-51725 in its entirety, go to: www.unitedfiresystems.net.
1.3. Functional Description. See Figures 1, 2, 3, and 4. STANDPIPE-PAC™ consists of the following:
(1) Air compressor with automatic control switch. The air compressor compresses atmospheric air for
pressurizing the standpipe. The automatic control switch starts the compressor when the pressure is below
13 PSIG, and stops the compressor when the pressure exceeds 18 PSIG.
(2) Desiccant air dryer. The desiccant air dryer dries the compressed air before entry into the standpipe, as
required by Boston FD TCM3-51725.
(3) Low-limit pressure sensing switch. This switch senses when the pressure in the standpipe drops below 7
PSIG, as would happen if a standpipe valve was inadvertently opened, or a portion of the piping was
inadvertently removed. This switch sends its signal to the control unit (8).
(4) High-limit pressure sensing switch. This switch senses when the pressure in the standpipe exceeds 23
PSIG, as may happen if the automatic control switch on the air compressor (1) fails. This switch sends its
signal to the control unit (8).
(5) Pressure gauge. The pressure gauge indicates the approximate pressure in the system in PSIG.
(6) Check valve. The check valve prevents entry of water into the STANDPIPE-PAC™ when the Fire
Department pumps water into the standpipe. This device is required by Boston FD TCM3-51725
(7) Lockable shutoff valve. This valve permits maintenance on the STANDPIPE-PAC™ without de-pressurizing
the entire standpipe. This device is required by Boston FD TCM3-51725, and per this directive, shall be
locked in the OPEN position.
(8) Control unit with power supply, backup battery, silence switch, and automatic dialer. The control unit accepts
the signals from the pressure sensing switches (4) and (5), and operates the signal horn (9). The silence
switch allows the signal horn (9) to be silenced. The power supply is dedicated to the system as required by
Boston FD TCM3-51725, and provides for backup battery power for the control unit. This device also
provides an automatic dialer for connection of telephone lines for off-site notification.
(9) A signal horn. Additional signal horns may be connected so that signaling may be heard throughout the site.
(10) A junction box for connection of 120 VAC, 60 Hz, single phase power for both the air compressor (1) and
the control unit (8). Connection of 120VAC 60 Hz single phase in this box provides power for both the air
compressor (1) and the control unit (10).
(11) An outlet for connection of piping to the dry standpipe. 1/2” NPT pipe (provided by installer) is run from the
outlet to a connection point on the standpipe.
(12) A disconnect switch to remove power from the air compressor (1). This switch facilitates testing and
maintenance of the system.
(13) A test / service device. See instructions in this manual for use of this device.
(14) A serial number nameplate.

(15) A manual air release bleed valve for Fire Department use. This device is to be installed near the siamese
connection feeding the standpipe. A cap and chain is provided to protect the outlet. An instruction
nameplate is also provided. This nameplate is to be securely fastened near the valve.
(16) A remote weatherproof audible / amber visual device with weatherproof backbox and identification
nameplate. This device is required by Boston FD TCM3-51725. The installer must locate this device
immediately outside the location of the STANDPIPE-PAC™, and wire the device in accordance with the
instructions in this manual.
(17) An auxiliary condensate drain device. This device permits manual draining of water in the piping near the
STANDPIPE-PAC™ unit, to help prevent water entry into the unit and pipe blockage without removing all
air from the standpipe. (Figure 4)

2.2. Determining Desired Fill Time. Per Boston FD TCM3-51725, any impairment lasting 4 hours or more
requires shutdown of the construction / demolition site and notification to the Boston Fire Department. The
usual criterion is to fill / refill the standpipe in less than 4 hours, with margin for work performed for
construction / demolition. NOTE: The NFPA 13 sprinkler system rule of 30 minutes “fast-fill” DOES NOT
apply to standpipes.

Sch. 40 black pipe and Class 150 fittings. The tee to connect the STANDPIPE-PAC™ shall be located after the
check valve, and should be located before the drain valve. Connect 1/2” pipe to point labeled OUTLET on
STANDPIPE-PAC™ unit. Ensure that the standpipe is NOT PRESSURIZED prior to cutting in the tee at the
installation location.
All dry standpipes should always be maintained as dry as possible. This is to minimize internal corrosion year round,
as well as to minimize ice accumulation and blockage during cold weather.
To facilitate drainage, the low point of the standpipe must have a main drain valve, and all pipe should be pitched
towards that main drain valve. The main drain valve should be opened on a regular basis, permitting any water
accumulation or pooled water from testing to drain.
Dry standpipes installed with supervisory systems shall be installed per Figure 9 above. The diagram indicates several
important facts:
1. Where possible, the STANDPIPE-PAC™ should NOT be the low point of the dry standpipe system.
2. The piping from the STANDPIPE-PAC™ should be pitched away from the STANDPIPE-PAC™ so that
accumulated water drains away from the STANDPIPE-PAC™ outlet.
3. Install the Auxiliary Condensate Drain Device where shown on Figure 10, per 3.3.4.
3.3.3. Manual Air Release Bleed Valve. See Figure 2. Locate the manual air release bleed valve on the exterior of
the building in proximity to the fire department siamese connection feeding the standpipe protected by the
STANDPIPE-PAC™. Attach the cap and chain to the valve. Secure the provided nameplate to the building or the
valve so that the fire department can clearly identify the purpose of the valve and follow the instructions on the
nameplate.

CAUTION
Failure to confirm that the standpipe is NOT pressurized could result in personal injury and / or property damage.

3.3.4. Auxiliary Condensate Drain Device
1. Determine the installation location of the Auxiliary Condensate Drain Device:
a. Locate the device in close proximity to the outlet of the STANDPIPE-PAC™.
b. The location of the STANDPIPE-PAC™ and the Auxiliary Condensate Drain Device MUST be in an area
protected from freezing temperatures (over +32°F (0° C)).
c. The device MUST be installed vertically –see Figure 9 and Figure 10.
d. No separate bracket is necessary –the inlet piping connection should be satisfactory to hold the device in
place.
2. Remove and discard plastic plug from device inlet (Valve 1).
3. See Figure 10. Attach a ½ inch close pipe nipple and the bull of a ½ inch pipe tee to device inlet.(Valve 1)
4. Install a convenient length of ½ inch threaded pipe between the outlet of the STANDPIPE-PAC™ and the run of
the tee attached to the device inlet.
5. See Figure 10. Connect ½ inch pipe to the remaining run of the tee attached to the device and the inlet to the dry
standpipe. Pitch the pipe to drain away from the device.
6. See Figure 4. Attach Instruction Nameplate to wall in close proximity to device.
IMPORTANT
The Auxiliary Condensate Drain Device does NOT take the place of a standpipe system main drain. Ensure that a
main drain valve is properly installed at the lowest point of the standpipe, in an accessible area, where all the water
from the standpipe may be properly drained.
