cGas Detector Analog Transmitter - Operation Manual
VDC or 12 VAC.
NOTE: WARRANTY VOID IF SOLID-CORE WIRE IS USED AT THE WIRING
TERMINAL STRIP.
When using solid core wiring for distribution (in the conduit), use stranded wire
pigtails 18 AWG within the enclosure to connect to the circuit board. The rigidity
of solid-core wire can pull a soldered terminal strip completely off a circuit
board and this will not be covered under warranty.
6.6.1 Analog Wire Gauge vs Run Length
The table below shows the maximum cable length between the cGas Detector
and the controller for normal installations (a separate signal line from the
controller for each cGas Detector is required).
