ELECTRICAL INSTALLATION
Field wiring required for a detection system includes connection of AC power, connection of
two conductor cable between the receiver and the sensor/transmitter, and connection of the
battery back-up unit if it was purchased with the system. ATI does not supply an AC power cord
with the system. A 25 foot length of 2 conductor interconnect cable is supplied for connection of
the sensor/transmitter to the receiver. Longer lengths up to 1000 feet may be used when
required.
Single point detection systems are supplied with the power supply, receiver, and optional horn
factory wired as shown in Figure 1-5 below.

A
GasSens
gas detection system will always contain an A14 Receiver and an A11 Sensor/
transmitter. Normally, an A17 Power Supply module will also be included, and an A19 Battery
Back-up Unit will often be used to provide standby power for the system. Figures 1-8 and 1-9
provide interconnect wiring diagrams for typical single channel systems.
