6.10 Alarm and Signal Wiring Connections for CXCM
For terminal block connections, the recommended wire sizes are 0.75 to 0.14mm 2 (#18 to #26 AWG) for the
temperature range of 0 to 50 deg. C (as per UL/CSA).
For insulation displacement receptacles, the recommended wire size is 0.75mm 2 (#18 AWG).
CAUTION: to reduce risk of fire, use only 0.129mm 2 (#26 AWG) or larger wire.
