After power up, the firmware revision level will be
indicated on the LCD followed by an LED/LCD and
beacon self test. The controller will then begin
scanning connected detectors and display their
reported gas concentration on the LCD and status
information on the LED matrix.
EXTERNAL ALARMS
One switched 24V DC contact marked "BEACON" is
available for the connection of an external alarm
device. The terminals can sink up to 300 mA at 24V DC.
Form C relay contacts are provided for FAULT, LOW
ALARM and HI ALARM conditions.
Use the remaining cable glands to gain access to the
interior of the Controller. Locate the relay connectors,
secure the wire leads to the connectors
2-CHANNEL SETUP PARAMETERS
During power up the perimeter visual alarm and the
audible alarm will both run through a test cycle. The
POWER green LED for the controller (see Figure
16) will illuminate. When the Hansen gas detector
establishes communications with the 2-channel
Controller the FAULT amber LED for the controller (see
Figure 16) will go from illuminated to not illuminated. It
can take up to 5 minutes for the Hansen Gas Detectors
to warm up.
As default all settings on Switch 1 and Switch 2 are in
OFF position. If using the Hansen 2-Channel Controller
to interface with a BMS as a child the MODBUS

protocol needs to be configured (Refer to Figure 21).
Using switch 1 (SW1) on the underside of the lid of the
Controller, use setting 4 to acknowledge whether the
Hansen gas detector will need to have the terminating
resistor engaged. Please see MODBUS protocol
for best practice. All of the settings of the Hansen
gas detector must match the BMS system to work
correctly.
The (3) form C relays that are included in the Hansen
gas detector (fault, low alarm, high alarm) can be
configured to be fail safe. The fail safe mode will be
set to its fault or alarm state during loss of power
until power is restored. The fail safe mode can be
configured for each of the individual relays and is
done using SW1 settings 1, 2 and 3. If fail safe mode is
desirable for the relays change settings to ON.
Switch 2 setting 3 is enabled if a second Hansen gas
detector will be connected to this 2-Channel Hansen
Controller. As a default, the Controller is set to one
gas detector input.
The (2) analog outputs can be configured to 4-20mA,
1-5V or 2-10V depending on user preference. When
configured both analog outputs will be configured
the same (i.e., both 4-20mA, both 1-5V, or both
2-10V). Using SW2 settings 4 and 5 set the desired
configuration. Output cannot be on analog signal and
MODBUS.
