NOTICE
The TYCO Model TF Vane Type Waterflow Switch
described herein must be installed and maintained
in compliance with this document, in addition to the
standards of any other authorities having jurisdiction.
Failure to do so may impair the performance of the
related devices.
The owner is responsible for maintaining their fire
protection system and devices in proper operating
condition. Contact the installing contractor or product
manufacturer with any questions.
General description
The TYCO Model TF Vane Type Waterflow Switch is
designed to detect a waterflow condition in a wet sprinkler
system.
The switch assembly contains single-pole, double-throw
(SPDT) contacts, and an adjustable pneumatic vane. The
switch activates when a flow rate exceeding the flow
sensitivity of the switch occurs. The flow condition must
exist for a longer period than the retard delay setting of
the vane for the switch to operate.
The switch assembly options include two arrangements:
• Saddle mount: See Figure .
• Thread mount: See Figure .
The standard saddle mount option is available in a 2 in.
to 10 in. size range. The thread (NPT) mount option is
available in a 1 in. to 2 in. size range.
The cover incorporates a tamper resistant screw that
requires a special tamper resistant key for removal. One
key is supplied with each device.

Operation
Waterflow in the pipe/fitting deflects the vane as shown
Figure 3. The vane deflection triggers a switch featuring
a retard which can be set to a specific time delay. This
setting is called the retard delay.
The switch contains a pneumatically controlled
mechanical delay mechanism. The delay mechanism will
reset if the waterflow stops before the entire time of the
delay timer has elapsed.

Installation
The TYCO Model TF Vane Type Waterflow Switch must be
installed according to the instructions in this section.
Installing the saddle mount switch
Before you begin:
• The saddle mount switch must be installed according
to the instructions in this section.
• The saddle mount switch must be installed vertically or
horizontally.
• For horizontal installation, the switch should be
installed on top of the pipe.
• Do not install the saddle mounted switch within
6 in. (15 cm) of a fitting that changes the direction of
the waterflow.
• Do not install the saddle mounted fitting with
24 in. (60 cm) of a drain or valve.
To install the saddle mount switch, complete the following
steps:
1. Install the switch in in a location where there is
adequate clearance for installation or removal.
See Table 1 for information about the switch
dimensions.
2. Drain the system and drill a hole in the pipe
according to the dimensions in Table 1. Use a hole
saw in a slow speed drill to make the cut.
Note: The hole should be perpendicular to
the center of the pipe as shown in Figure 4.
3. Remove all burrs and sharp edges from the hole.
Clean and remove all scale and foreign matter from
the inside of the pipe for a distance equal to the
diameter of the pipe on either side of the hole.
Clean the outside of the pipe around the hole to
remove any dirt, metal chips or cutting lubricant.
4. Roll the pneumatic vane into the hole in the
opposite direction of the waterflow as shown
in Figure 5; do not bend or crease it. Seat the
gasket against the saddle and mount the vane
into the pipe. Insert the vane so the arrow on the
saddle points in the direction of the waterflow. The
bushing should fit inside the hole in the pipe.
5. Install the U-bolt and tighten the nuts alternatively
to ensure a uniform seal. See Table 1 for torque
values.
6. Check to see that the vane does not rub or bind in
any way. If the vane rubs, remove the detector and
correct the issue before re-installing.
Model TF Vane Type Waterflow Switch APAC Only 5

Note: If removing the detector, hold the vane
and start to curl it. While curling the vane,
slowly pull it out of the pipe. Do not pull out
the vane only by the saddle.

Installing the thread mount switch
Before you begin:
• The thread mount switch must be installed according
to the instructions in this section.
• The thread mount switch must be installed vertically or
horizontally.
• For horizontal installation, the switch should be
installed on top of the pipe.
• The device should not be installed within 6 in. (15 cm)
of a fitting that changes the direction of the waterflow,
or within 24 in. (60 cm) of a valve or drain.
To install the thread mount switch, complete the following
steps:
1. Install the switch in a location where there is
adequate clearance for installation or removal. See
Table 2 for information about the pressure switch
dimensions.
2. Select the correct vane according to the pipe size.
3. Screw a 1 in. NPT fitting into the piping.
Note: When using TEFLON tape, do not
use more than three wraps of tape on the
threads.
4. Verify the vane does not rub or bind in any way. If
the vane rubs, remove the detector and correct the
issue before re-installing.
Wiring the switch
Before you begin:
• The switch must be wired according to the instructions
in this section.
• The installation must comply with local electrical codes.
• Do not leave the cover off for an extended period of
time.
CAUTION
An uninsulated section of a single conductor
should never be looped around the terminal to
serve as two separate connections. The wire
must be severed into two separate connections
to provide supervision of the connection should
a wire become dislodged.
Model TF Vane Type Waterflow Switch APAC Only6

Figure 6: Correct wiring practice
To wire the switch, complete the following steps:
1. Remove the tamper resistant cover screw with the
special tamper resistant key.
2. Route the wiring through an agency approved
conduit connector and attach the connector to the
switch.
Note: If a second conduit entry is required,
remove the knockout plug. To remove the
knockout plug, place a screwdriver on the
inside edge of the knockout. Do not place the
screwdrive in the center.
3. Connect the wiring to the appropriate terminals
according to the correct wiring practice as shown
in Figure 6, and the required configuration as
described in Figure 7.
Note: A ground screw is provided with each
switch. When grounding is required, clamp
the grounding wire between two conduit
entrance holes with the ground screw.

Adjusting the retard delay setting
About this task:
The switch retard delay setting may be adjusted in the
field from the default setting in order to change the
retard delay. Figure 8 shows the location of the retard
adjustment wheel for adjusting the retard delay.

2 Cover
5 Saddle or thread connection
10 Retard delay adjustment wheel
11 Cover gasket
1. Rotate the retard adjustment wheel as follows to
adjust the retard delay:
- Clockwise to increase the retard delay
- Anti-clockwise to decrease the retard delay
Note: The retard delay should be set at the
minimum delay required to prevent false
alarms.
2. Re-test the switch to ensure the retard delay is
accurate.
Care and maintenance
The TYCO Model TF Vane Type Waterflow Switch must be
maintained and serviced in accordance with this section,
in addition to any specific requirements of the NFPA, and
any impairment must be immediately corrected. The
inspection procedure must be performed as described.
Before closing a fire protection system control valve for
inspection or maintenance work on the fire protection
system that it controls, permission to shut down the
affected fire protection system must first be obtained
from the proper authorities and all personnel who may
be affected by this action must be notified. After placing
a fire protection system in service, notify the proper
authorities and advise those responsible for monitoring
proprietary and/or central station alarms.
The owner is responsible for the inspection, testing,
and maintenance of their fire protection system and
devices in compliance with this document, as well as
Model TF Vane Type Waterflow Switch APAC Only 7

with the applicable standards of the NATIONAL FIRE
PROTECTION ASSOCIATION such as NFPA 25, in addition
to the standards of any authority having jurisdiction (AHJ).
Contact the in stalling contractor or product manufacturer
with any questions.
It is recommended that automatic sprinkler systems
be inspected, tested, and maintained by a qualified
inspection service.
Inspecting the switch
About this task:
The inspection procedure must be performed as specified,
in addition to any specific requirements of the NFPA, and
any impairment must be immediately corrected.
Test the switch periodically after installation in accordance
with applicable NFPA codes and standards and/or the
authority having jurisdiction (AHJ). A quarterly schedule is
recommended.
Inspect the switch for leaks monthly. If a leak is found
replace the switch.
