INSTALLATION

The Controller has been thoroughly inspected 

and tested prior to shipment from the factory. 

Nevertheless, it is recommended that the instrument 

be re-checked prior to installation. Upon receipt, 

inspect the outside of the enclosure to make sure 

there are no obvious signs of shipping damage. 

Loosen the screws on the enclosure lid and open 

the front panel. Visually inspect the interior of the 

enclosure for loose wires or components that may 

have become dislodged during shipment.

The Controller should be centrally located in the 

facility (preferably outside of the mechanical room) 

and should be easily accessible for visual monitoring 

and servicing. This is the “split architecture design” 

for safety of the operator. Dirt, grease, and oils can 

adversely affect the operation of the Controller. This 

Controller should be installed out of direct sunlight in 

a clean, dry area that is not subject to temperature or 

humidity extremes. Installation in a mechanical room 

is acceptable provided reasonable environmental 

conditions exist. If there is a question, consider 

installing the unit outside of the mechanical room in a 

cleaner area of the facility.

The Controller should be installed plumb and level 

and securely fastened to a rigid mounting surface. 

The enclosure utilizes four mounting holes designed 

for #6 (or M3.5 or M4) pan head fasteners (included). 

Mounting holes are located in the four corners of 

the enclosure, accessed by opening the front panel. 

Install and adjust the screws as necessary to hold the 

unit securely against the mounting surface. 

The Controller enclosure features M20 two cable 

glands that are intended for power entry. If conduit 

is preferred simply remove one of the M20 glands 

and install a suitable ½” conduit adapter. Locate the 

AC power and Ground on the power input terminal 

block. Secure the incoming AC power neutral (white/

blue) and live (black/brown) and ground wires to the 

appropriate terminals using a screwdriver on the press 

to release tabs as shown below.

The Controller is connected to Hansen gas detectors 

using a shielded twisted pair instrument cable 

(Belden 3106A or equivalent). The maximum distance 

between the furthest gas detector and the Controller 

is 1000 feet (1372 m) when only using MODBUS 

communications. The available distance is less when 

using the Controller as the power supply for gas 

detectors. The total power available for gas detectors 

is 51W. Careful attention to voltage drop over distance 

with a suitable wire gauge employed is also required. 

Use any of the remaining cable glands to gain access 

to the interior of the unit. The RS-485 communication 

wiring between the gas detector and the Controller 

must be connected in the following manner: 

1. Locate the RS-485 connector in the gas detector. 

2. Connect one lead of a twisted shielded pair to the 

“B” connection point; note the wire color. 

3. Connect the second wire to the “A” connection 

point; note the wire color. 

4. Connect the ground to the “GND” connection point 

5. Connect the shield or drain wire to the “SH” 

connection point. 

Locate the RS-485 connectors in the Controller. The 

left RS-485 connector is for downstream “child” 

devices (includes a dedicated shield position) and the 

right RS-485 connector is used to connect to “parent” 

devices upline, such as building management controls. 

A second RS485 connector allows a Building 

Management System (BMS) to communicate with the 

Controller via MODBUS protocol. The connection is 

established using a shielded twisted pair cable such 

as Belden 3106A. Use any of the remaining service 

cable glands to gain access to the interior of the 

Controller. Locate the RS485 upline connector, secure 

the wire leads to the connector in the orientation 

as displayed on the board. Check to make sure the 

polarity matches the wiring to the BMS. The shield 

connection should only be grounded at the BMS 

device and should not be connected at the controller. 

8-CHANNEL SETUP PARAMETERS

Pressing a Channel number key will bring up a 

scrollable channel detail screen with detector specific 

information. Pressing the channel number key a 

second time will access the channel setup menu. 

The system level menu is accessed by pressing the 

OK key while the main screen is being displayed. The 

currently selected menu item is indicated with triangle 

pointers to the left and right of the description. If 

the menu list is longer than can be displayed, up 

and down arrow keys on the right side of the screen 

will indicate additional items are available by either 

scrolling up or down.

 

Some of the screens you will access will require 

data entry, such as the date/time setup or location 

description. These screens will appear with a 

character selected, as displayed below. Use the up/

down Arrow keys to scroll through the characters 

provided for that character’s place. Use the left/right 

Arrow keys to move the cursor to the next character. 

When all character selections for the screen are 

completed, press ENTER to accept the entries.

 

Before using the Controller various parameters must 

be set by the user based on how the controller has 

been wired. These parameters are accessed from the 

main menu by selecting ”CONTRLR CONFIG”.

 

The system level menu is accessed by pressing the 
OK key while the main screen is being displayed. The 
currently selected menu item is indicated with 
triangle pointers to the lem and right of the 
descrip;on. If the menu list is longer than can be 
displayed, up and down arrow keys on the right side 
of the screen will indicate addi;onal items are 
available by either scrolling up or down. 

 

Some of the screens you will access will require data 
entry, such as the date/;me setup or loca;on 
descrip;on. These screens will appear with a

completed, press ENTER to accept the entries. 

 

Before using the Controller various parameters must 
be set by the user based on how the controller has 
been wired. These parameters are accessed from the 
main menu by selec;ng ”CONTRLR CONFIG”. 

 

From the RELAY menu, each of the three relays can 
be configured for either normal or failsafe opera;on. 
The default is normal, meaning normally open 
contacts will close with the event corresponding the 
relay designa;on. If fail safe is selected the relay will 
be normally energized and will be de-energized with 
the relays designated event or a power failure. 

 

 

The op;onal beacon, if installed, and the internal 
buzzer may be enabled to indicate an alarm 
condi;on. When enabled, the beacon will be 
energized, and the buzzer will beep, if either a low or 
high alarm condi;on exists. 

 

Fault latching defaults to DISABLED, allowing the 
fault indica;on to clear with the condi;on without 
user interven;on. When ENABLED the fault 
indica;on will persist amer the condi;on has cleared, 
un;l a user clears the current faults by selec;ng 
“CLEAR FAULT” from the diagnos;c menu. 

 

To use the Hansen smart phone app, before 
connec;ng you must ENABLE Bluetooth from this 
menu screen. 

 

From the LCD contrast seqng screen, use the arrow 
keys to adjust the contrast from 1-63, with 30 being 
the default. 

 

The brightness of front panel LEDs can be adjusted 
from 0-10. A full bright seqng of 10 will be visible 
from a long distance but may be too bright when the 
user is opera;ng the keypad. For this reason, when 
the keypad is in use the LED brightness will auto-dim 
to a comfortable level, and resume the programmed 
brightness seqng amer a period of keypad inac;vity
