General
Description
The TYCO Model TSV-D SMART Air
Vent, Dry provides automatic oxygen
venting in dry pipe fire sprinkler
systems. As a fire sprinkler system is
filled with a continuous supply of nitro-
gen gas from the TYCO Nitrogen Gen-
erator, the SMART Air Vent allows
oxygen rich gas to be vented from the
fire sprinkler system. Over a period of
14 days, the SMART Air Vent almost
completely removes oxygen from the
fire sprinkler system (< 2% oxygen).
After 14 days, the SMART Air Vent
automatically closes and prevents con-
tinuous venting.
The SMART Air Vent includes two sep-
arate components:
• vent assembly
• electric control box
The vent assembly is equipped with a
ball valve to be connected to the fire
sprinkler riser. The electric control box
is available in two inline voltage models
- 120 VAC/60 Hz or 230 VAC/50 Hz.
The SMART Air Vent must be installed
as shown on the engineering design
documents. If a location is not speci-
fied, install the SMART Air Vent on the
fire sprinkler system riser on the system
side of the main control valve. The elec-
tric control box must be installed on
an adjacent wall near the fire sprinkler
system riser, as shown in Figure 4.
The SMART Air Vent is equipped with
a levered float valve that allows gas to
discharge but prevents liquid water
from leaking through the restricted
venting orifice in the event that water
enters the fire sprinkler system.
A back pressure regulator is also
included to prevent total system
depressurization from the vent assem-
bly before the vent is electronically
closed.
The restricted venting orifice allows
oxygen to be vented from the fire
sprinkler system at a controlled rate to
achieve a minimum nitrogen concen-
tration of 98%. A special fitting is pro-
vided to receive 5/32 in. tubing when
the vent is used in conjunction with
the TYCO Model TSGA SMART Gas
Analyzer.
The SMART Air Vent is equipped with
an electronic solenoid valve that must
be wired to the electric control box
(conductors not included). The control
box automatically closes the vent after
14 days as the desired nitrogen con-
centration will have been achieved. The
control box is equipped with an on/off
switch and a vent button to provide a
means to restart of the venting process
should oxygen be reintroduced into the
fire sprinkler system. See Figure 1.
NOTICE
The TYCO Model TSV-D SMART Air
Vent, Dry described herein must be

ance with this document, in addi-
tion to the standards of any other
authorities having jurisdiction.
Failure to do so may impair the per-
formance of the related devices.
The owner is responsible for main-
taining their fire protection system
and devices in proper operating con-
dition. Contact the installing contrac-
tor or product manufacturer with any
