2.8 CONNECTING EXTERNAL ALARM ANNUNCIATORS
Five form C relay contact outputs are available for connection to external, user-supplied alarm annunciators. Figure 2-13 shows the
Interface Board and the row of connectors (X6) provided for these connections. Review the alarm and relay contact specifications in
Section 1.2.11 Alarm Specifications to ensure compatibility with external annunciators and other equipment before proceeding.
Alarm relay outputs are provided for remote annunciation of fault conditions. All relays are user programmable through the SageView
software.
As shown in Figure 2-13, each relay has three connections: common, normally open, and normally closed. The normally open (NO)
and normally closed (NC) labels are for an un-powered Sageon III Power System. Relay coils are energized during normal Sageon III
Power System operation. During an alarm, the appropriate relay coil is de-energized.
IMPORTANT:
When the relay contacts are connected to a reactive load, such as a solenoid or relay coil, the load must be shunted by
a transient suppression device to prevent damaging relay contacts.

2.9 BATTERY TEMPERATURE SENSORS AND KITS (OPTION)
The Multiple Battery Temperature Board is included in the Sageon III distribution. It can accommodate up to four battery temperature
sensors. Temperature sensors are ordered separately. If ordered with the system, the sensors are connected to the Multiple Battery
Temp Board and the sensors and wires then coiled and tied to the return bus.
If not ordered with the Sageon III Power System, an Ambient and up to four Battery Temperature Sensor can be ordered separately.
Installing the Sensors:
Open the distribution door and locate the Multiple Battery Temperature Board. Locate the coiled sensors.

If not already connected, plug the battery temperature sensor connectors and the ambient temperature sensor into the Controller
backplane board. See Table 2-4 for the connectors. The connectors are keyed.
