2. Hang S 3 with four screws.
3. Make sure all power supplies are disconnected before breaking any wires, or reaching into the
system enclosure.
4. Open the S 3 and find all connections. Refer to wiring diagrams in Section 12 of this manual.
5. Run temperature sensors out to locations inside the house. Be sure that the sensors are in a safe
location, free from any temperature influences (direct sunlight, water, etc.) Use care when
securing sensor wires so that the wire is not accidentally cut. Any short, or break in the wire will
cause improper sensor operation. Next, run the wires into the enclosure via the watertight
connector at the bottom of the box. The wires should be cut off and stripped. They next should
be attached to the terminal block in the positions marked Sen 1, Sen 2 and Sen 3. Note that the
sensors are not polarity sensitive, and it therefore makes no difference as to which wire goes to
which sensor terminal.
6. After the siren is mounted, it should be wired into the control box. This is done at the terminal
block locations labeled siren red and siren white. Note that polarity is important here and that the
red siren wire must be connected into the siren red terminal block position and the same for the
white wire. Note also, any 12VDC device that uses less than 1.5 Amps of current could be
connected in the siren’s place.
7. Connect wires from Alarm terminals to the alarm circuit or relay box. (See wiring diagrams in
Section 12.7 for locations of terminals.)
8. If using a modem, connect wires from Modem terminals to the modem circuit or relay box. (See
wiring diagrams in Section 12.7 for locations of terminals.)
9. If necessary, connect the S 3 to the Hired Hand Farm Manager Network. (See the connections in
Section 12.10 of this manual.)
10. Connect the AUX and CONTROL AUX connections. Refer to Section 12.8 diagram.
11. Remove jumpers for AUX & CONTROL connections if being used.
12. If connecting to an EV 3000/3001 controller, connect Local Net and Back-Up Network setting in
Evolution controller (Plus models ONLY).
13. Wire Stage to Relay Card for Back-Up operation.
14. Set Stage Jumpers on Relay Cards in S 3 or EV 3000/3001. Refer to Section 12.6 diagram.
15. Connect Vent/Tunnel Overrides.
16. Connect AC Power. Refer to Section 12.3 diagram.
17. Program the S
3
. Refer to Section 6.
10.3 Sensor Recommendations
It is important to note the Hired Hand temperature sensors are fabricated using thermistors and are not
interchangeable with sensors commonly used on controllers from other manufacturers. The three temperature
sensors may be installed in a variety of ways. It is recommended that a sensor be located high enough from
the floor so that livestock or poultry can not peck at it. It is also essential that the sensor not be hung in front
of heaters, fans or other devices that would cause false readings. If a sensor is to be run from one building to
another, it is recommended that the connection be made with underground-rated wire buried between the two
structures. This recommendation is to reduce the effects of lightning.
Once again, the temperature sensors should be dropped as low in the house as possible while still being out
of reach of the livestock or poultry. And, as discussed earlier, it is recommended that the operator press the
Test button for ten to fifteen seconds at least twice a week to verify the operation of the alarm as well as to
condition the livestock or poultry to the sound of the siren.
