Hired-Hand Emergency Back-Up and Alarms: Secondary Sensing System Expansion - Manual (Page 19)

connecting the Auxiliary Inputs (See Section 13.11 for a connection diagram). Each of the connections
has an IN and OUT terminal. If, at any time, the connection between the IN and OUT positions is broken
(opened), the alarm will sound. There are many devices on the market that could be used with these inputs.
For instance, water pressure switches, light meters, and thermostats could all be used. The S
3 will wait 30
seconds after an auxiliary input is broken before triggering an alarm.
8.1.3 Power Out
The Power Out alarm indicates that there has been no AC electricity present on the alarm power feed for at
least 30 seconds.
AC Main Power Fuse:
If it is found that there is power present at the electrical outlet and the Power Alarm is ON at the S
3
Expansion, the 3 Amp slow-blow fuse located on the S 3 Expansion PCB184 circuit board (Fuse F1)
should be checked for a blown fuse. To replace a fuse, disconnect AC power from PCB184, disconnect the
positive (+) battery terminal from the battery, carefully replace the blown fuse with the correctly sized
replacement fuse, reconnect the positive (+) battery terminal to the battery, reapply AC power to PCB184,
and verify the power alarm has cleared. The S
3 Expansion will wait 60 seconds after a Power Out
indication before triggering an alarm. Refer to the S 3 Expansion PCB184 Circuit Board Layout in Section
13.5 and Fuse Replacement in Section 10.4.
Terminal Connections to the Battery:
If AC power is out or disconnected from the S
3
AND none of the S
3
Displays or LED’s are ON, verify that
the Battery Positive (+) and Battery Negative (-) quick-connect terminals are securely attached at the
battery and at PCB184. Also verify secure connections at PCB184 J7, the Power Switch, and at PCB179
J3. Refer to the S
3
Wiring in Section 13.1, 13.4, and 13.5.
If the AC power is OFF for an extended period of time with the alarms ON, the Back-Up Battery will
eventually be drained of all power. Refer to Section 10 for additional troubleshooting information.
8.2 Alarm Outputs
The S 3 Expansion has two alarm outputs. These can be used individually or simultaneously. The alarm
outputs are:
8.2.1 Siren
The siren hookup to the S
3
Expansion will deliver a 12 volt DC signal with a current up to 1.0 amps.
Many operators want to mount the siren a long distance from the controller. Sometimes, this is desirable in
order to locate the siren closer to their dwelling, sometimes to get it away from their animals. The use of a
small gauge wire to connect the S
3
Expansion to the siren could cause a great deal of voltage drop. This
voltage drop, in turn, can cause the siren to become inoperative. If the operator wants to mount the siren
more than 50 feet from the controller, a relay with a 12VDC rated coil should be used to switch current to
the siren. When a relay is added, the operator must provide a separate battery and charger for the siren
circuit.
8.2.2 Dry Contact (N.O. and N.C. Contacts)
The S 3 provides a set of dry contacts that can be used to trigger a modem, auto-dialer or other auxiliary
equipment. Both normally open (N.O.) and normally closed (N.C.) contacts are available. See Section
13.10 for a wiring diagram.
9. Back-Up System Operating Conditions
The S 3 Expansion Back-Up System operates differently based on whether it is connected to a Evolution 3000/3001
control system or if it is a stand-alone (not connected to the Evolution 3000/3001 local network) system. Of course
the system loses some of its functionality when it is not connected to the Evolution 3000/3001 network but its
capabilities are still much better than other Back-Up system alternatives. This section will be divided into two sub-
sections.
