Loosen two screws on bottom front of
chassis.
Separate main chassis from mounting
bracket assembly.
Mount the Midas®mounting bracket
assembly onto the LonWorks®interface.
Tighten screws.
Align the PCB at the top rear of the main
chassis with the connector located at the
top of the mounting bracket assembly.
Slide the main chassis backwards on the
mounting bracket assembly so that the
PCB and connector and tubes engage
simultaneously.

Reset Fault F49 if present.
Set alarm levels and other parameters as
desired.
Confirm that the Midas IP parameters are at
default values. If changed, the DHCP client
must be set to ‘n’. The IP address must be
restored to 169.254.60.47 and the subnet
mask must be restored to 255.255.255.0

The Midas®LonWorks®interface module is
installed behind the standard Midas®gas
detector as shown in Figure 1. Power and
data connections are supplied directly to the
LonWorks®interface module. All power and
communication to the Midas®unit is provided
via the LonWorks®interface.

Gently pry the clear locking
tab outside of the yellow jacket
on both ends of the cable as
shown.
Ensure yellow jacket has not moved out of
position when inserting to the Midas
®
or LON
Module connectors (clear tab is to rest on top of
the yellow jacket bubble).
Caution: Do not over-extend the tab as damage
may result.
Bend the cable into 1½ loops
as shown. The two connectors
should be approximately 3 cm
apart. This is to reduce torque
on the installed connector.
Plug the cable into the Midas
and the Interface as shown.
Loosen the black plastic cable
locker on the bottom of the
Midas. Slide this clamp under
the cable locking tab to
prevent the tab from being
depressed. Tighten the locker.

Check the part number and type of sensor
cartridge is correct.
Check the “activate by” date.
Remove sensor cartridge from packaging.
Carefully push the sensor cartridge into
the sensor cartridge chamber until fully
seated.
Lock the sensor cartridge in place using
the tabs on both sides of the sensor
cartridge.
Confirm that the power switch in the
mounting bracket assembly is in the ‘on’
position.
Refit the unit cover by aligning the slots
either side with the locating tabs on the
mounting bracket assembly.
Tighten the thumbscrew located on the
front panel.
Install the supplied RJ-45 cable between
the Midas®and the LonWorks®interface.

Wiring Notes:
Maximum wire size is 1.5 mm (16AWG)
Input voltage range is 21.6 to 26.4 VDC.
It is mechanically possible to misalign Plug 1 and Plug 2. Care should be taken when
inserting plug to assure correct alignment.
Plug 1 and Plug 2 are internally connected in parallel to facilitate wiring in bus topology.
LonWorks FT-10 wiring is polarity-insensitive. Lon A and Lon B may be swapped.
Note:
The Midas®LonWorks®interface draws approx 1.7 amps for approx 100 mS after power is applied.
External equipment should be sized appropriately. Additionally, the Midas®requires the supplied power
to rise to the minimum specification (21.6 VDC) within 500mS.
