safe/error mode or trouble condition. In this error mode the Fan* and Alarm relays will be activated indicating the trouble
condition at panel and the CM-12 display will flash the error. See section
Macurco External Horn/Strobe model number is 78-2900-0211-X, where X represents lens color, R for red lens cover, G for
green lens cover, B for blue lens cover, O for amber lens cover, C for clear lens cover. Sound pressure for Horn/Strobe model is
at least 85dB at 10 feet.
NOTE: The final installation of CM-xx system, including secondary wiring from controller to sensors shall comply with
requirements of "Class 1" in approved raceways or conduits.

3.3 Terminal Connection

3.3.1 6-Series Low Voltage

With the 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. 0°F to 125° F (-18°C to
52°C).
3.3.1.1 Mains Power Connection
Connect the CM-6 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 CM-6 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.
3.3.1.2 Fan Relay Connection
All of the SPDT Fan relay terminals are available at the Fan/Power modular connector. Each Fan relay terminal normally open,
common and normally closed (NO, COM and NC) can accommodate a wire size 12 to 22 AWG. To install the wiring for the relays,
disconnect the connector from the header. Strip the insulation of each wire back approximately 1/4 in. (6.5 mm), insert the bare
