In this application (
31T
Figure 3-7 6-Series Alternate Alarm Panel
31T
) the Fan or primary relay is used as a low-level alarm relay. The
Alarm or secondary relay is used as a supervisory relay when utilized in the normally closed configuration. The CD-6G monitors
all critical functions of the unit through software diagnostics that continually test and verify its operations. If a problem is found,
the unit will switch to a fail-safe/error mode or trouble condition. In this error mode, the Fan* and Alarm relays will be activated
indicating the trouble condition at the panel and the CD-6G display will flash the error. See section
31T

“tFS”

for options.
3.3 Wiring Connections
3.3.1 6-Series Low Voltage
With an exception of the safety ground, all field wiring is completed via modular connectors (provided). After wiring, simply plug
the modular connectors into the matching connectors on the back side of the detector.
NOTE: 22 to 12 AWG wire shall be used. Wire used shall meet the temperature range of the detector i.e., 32°F to 122° F (0°C to
50°C).
3.3.1.1 Power Connection
Connect the CD-6G to Class 2 power supply only. It is suggested to use a separate transformer for powering the unit or units
because of possible interferences from other devices on the same power supply. Connect the CD-6G to the control cables with
terminal plugs. When making connections, make sure the power is off. There are two terminals for Power: 12 to 24 VAC or 12 to
32 VDC, with no polarity preference ensure that the wire cannot be easily pulled from the connector. Plug the modular
connection into the Fan/Power connection and ensure that it latches into the header properly.
