SPM Flex Gas Detector

Wiring and tubing

CAUTION
!
• The safety of any system incorporating the SPM Flex gas detector is
the responsibility of the assembler of the system�
• Position a permanently-installed SPM Flex gas detector so that it does
not interfere with access to the dedicated circuit breaker�
• Use only the specified power adaptor/charger (see
page 63)�
• Use the power adaptor/charger only in indoor applications�
NOTE
Do not wire relays and 4-20 mA in the same wire bundle�

Typical fixed installation topologies

The SPM Flex gas detector has flexible installation options that allow the user to
select the one most suitable for a specific application� The detector is supplied
with weather-sealed connectors for power, Ethernet, and communications
(for relays or 4-20 mA)� The Ethernet port can be replaced with an appropriate
connection in accordance with local codes (allowing the user to wire directly to
the terminal block)� Install each detector near a dedicated circuit breaker�
This table shows the default wiring configuration for the IP-rated communication
connector when installed by Honeywell Analytics� The relays are labeled for the
factory default but the configuration can be modified to have a single alarm and
separate faults�
