Connecting sensors to transmitter

Connect the sensor to the transmitter as shown in the diagram below. The
maximum distance between sensor and power supply is 200 ft. (60 m) for
refrigerant and 500 ft. (160 m) for toxic and combustible gases. Color
coding (black, red, green, white) must be respected.
The first four sensors can be connected directly to the 301EM. Additional
sensors must have external power supplies (T300VA, 120/24Vac-300VA
Transformer) for every group of 4 sensors and communication must be in
daisy-chain connection
Note: Use 2-18 AWG wire gauge for toxic and explosives sensor power
wiring. Use 14 AWG wire gauge for refrigerant sensor power
wiring.
