SPM Flex Gas Detector
SPM Flex Gas Detector
Introduction
The SPM Flex gas detector is an extractive gas monitoring system that draws gas
samples locally or from a remote point to a Chemcassette® tape-based optical gas
detection system. A wide range of toxic gas Chemcassette cartridges are available
that enable detection of gases used or generated in semiconductor manufacturing
and industrial environments.
The SPM Flex gas detector, available in wall mounted and portable versions,
locally displays gas concentration, alarm, fault and status information via its backlit
color LCD and LEDs. A simple to use 4-button keypad adjacent to the display
provides the ability to set-up, review, operate and make changes to the detector’s
configuration. The intuitive display and menu structure are designed to require
minimal training. The SPM Flex has a local audio alarm with user-configurable
output levels. The detector can be used both indoors and outdoors in a wide range
of weather conditions.
The detector has flexible power and communications capabilities. These include
3 on-board relays, 4-20 mA analog output and Modbus/TCP outputs for signal
and service connectivity. The gas detector is equipped with a USB port for
configuration-sharing firmware updates and data downloads. For web-enabled
devices, web pages are available via the Ethernet port.
Standard operation conditions
The SPM Flex gas detector is designed for use in temperatures between 32ºF
and 104ºF (0ºC and 40ºC) and relative humidities between 0 and 100% (the
relative humidities are limited by tape and calibration). The sample line will require
additional hardware to remove moisture in high relative humidity conditions where
condensing may occur (the sample must be non-condensing). Dry conditions may
require humidification.
High-altitude applications
The SPM Flex pump is optimized for operation at altitudes between –1000 feet
(–305 meters) and 3000 ft. (945 m) above sea level. At altitudes above 3,000 ft.
(915 m), up to a maximum of 6,000 ft. (1,830 m), contact Honeywell Analytics for
calibration. (At 6,000 feet, pump capacity is reduced 18% and a flow-system
adjustment to the bypass valve is required. This must be performed by a Honeywell
Analytics certified technician. Contact Customer Service.)

Battery operation
The SPM Flex gas detector is supplied with a power supply/charger than can
connect the detector’s power connection and a standard wall outlet. (Ensure that
the correct power cable has been ordered for local operation.) The power supply/
charger is designed for indoor, dry-location use only. The lithium-ion battery pack
provides continuous operation of 6+ hours, depending on sampling conditions
and unit configuration. The battery’s charge time is typically 4 hours. The
detector can be operated while its battery is being charged (this may increase
the charge time). The battery is designed for 1000 charge cycles. Honeywell
Analytics recommends keeping the detector connected to the power supply/
charger when not in use to keep the battery fully charged.
! WARNING
•
The battery is not field-replaceable. Return the unit to Honeywell Analytics
if a battery replacement is necessary.
•
Risk of fire and burns. Do not open, crush, heat above 140ºF (60ºC), or
incinerate the battery. Follow manufacturer’s instructions.
How to extend battery life
Power consumption is optimized to extend battery life when not in monitor mode.
In addition, the unit should not be exposed to extreme temperatures which
shortens battery life. The time before recharging is required can be extended by
taking the detector out of monitor mode when it is not in use.

Wiring and tubing
Typical fixed installation topologies
The SPM Flex gas detector has flexible installation options to allow the user to
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.
•
Position a permanently-installed SPM Flex gas detector so that it does not
interfere with access to the dedicated circuit breaker.
Electrical connection is made via conduit directly to ports or via the connector
(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.
! CAUTION
Use the supplied power adaptor/connector only. (The adaptor is rated for
indoor use only.)

4-20 mA wiring
4-20 mA output is a three-wire connection that is configurable as sink, source, or
isolated, as shown in these following figures. Use an Allen wrench to remove the
wiring cover for access to the terminals. There must be a 200-600-ohm load on
the 4-20 mA line.
To ensure adequate resolution to overcome tolerance in the 4-20 mA reading, set
the full scale at an appropriate level. The SPM Flex issues a fault if the measured
4-20 mA reading is more than 0.8 mA (5% full scale) off from the expected drive
value.

The overall maximum load on the pump between the inlet and the exhaust should not exceed 10 inches H2O.
NOTE
Use Teflon Fluorinated Ethylene Polymer (FEP) tubing to ensure proper sample
transport.
Optional external filters can be installed to reduce noise or to monitor for gas at
the location of the detector. To do this an inline filter is simply connected to the
gas inlet port. The area around the detector is then being monitored as opposed
to a sample being drawn from a remote location.

Mounting options
! CAUTION
The SPM Flex detector must be installed only by qualified professional
personnel in accordance with local codes.
The SPM Flex gas detector has an optional mounting bracket assembly that is
easily affixed to a suitable vertical surface such as a wall, tool housing, mounting
plate on a pole etc.
Two mounting bracket options are available for fixed units: The standard kit is for
typical/new applications in which the detector is to be mounted to, for example, a
wall. A second option, a retrofit mounting, is a plate to be used when replacing a
Honeywell Analytics SPM detector with the SPM Flex detector.
Mount the detector with at least two appropriate fasteners (e.g., concrete screws
when mounting on concrete, etc.). The fastener combination must be capable of
securely holding four times the detector’s weight, approximately 40 lbs (18.2 kg).
When mounting the detector on sheetrock, the fasteners must be attached to studs.

At least 2 screws must be used when mounting the standard bracket to a wall.
Use the bracket as a template for determining the location of the holes to be
drilled in the wall. See the Specifications section on page 52 for a description of
the appropriate screws.
