select the one most suitable for a specific application� The detector is supplied
with weather-sealed connectors for both power and Ethernet, and with a third
port sealed� A third connector for communications is installed (for relays or
4-20 mA), or any of the ports can be replaced with appropriate connections in
accordance with local codes (allowing the user to wire directly to the terminal
block)� Install the detector near a dedicated circuit breaker�
CAUTION

• The safety of any system incorporating the SPM Flex gas detector is the
responsibility of the assembler of the system�

(see Figure 1 on page 10)� The terminals used are suitable for conductors of 24
to 14 AWG (0�5 to 1�8mm Dia�)� The use of 16 AWG (1�5 mm dia�) conductors is
recommended�
