Prior to assigning relays, configure the alarm levels (points). See Section ‘4.2.4 Viewing and setting
alarm levels (points)’, and then follow the steps and example below to configure the Alarm relays. Also
see Table 3, Example and Table 4.
1. Enter the main menu by activating any key to get the “enter main menu” prompt, then activate
switch 1 to select “yes”.
2. Activate the up key (switch 1) or down key (switch 2) until “Relay Assignment?” is displayed.
3. Activate the enter key (switch 3) to enter the option. The sub menu: ‘Alarm Relay 1’, ‘Alarm Relay
2’, ‘Alarm Relay 3’ as well as ‘Exit’ will be displayed.
4. Choose the Alarm relay (Alarm relay 1, Alarm relay 2, Alarm relay 3) for configuration, by using
the up- down arrow keys.
5. Activate the enter key (switch 3) to make the selection. The relay (RL) and channel (CH) with
alarm level setting will be highlighted. The alarm level settings available are: Point 1, Point 2, and
Disabled.
6. Under the specific relay with channel, activate the enter key (switch 3) to choose the appropriate
setting. See Table below.

7. Once the appropriate settings are chosen, use the up or down arrow key (switch 1) or (switch 2)
and switch 3 to exit.
Example: LEL combustible sensor connected to channel 1 and H
2
S sensor connected to channel 2.
1. Set Alarm Levels (points): Setup alarm levels for each channel, e.g. Channel 1 point 1 = 20% LEL,
Channel 1 point 2 = 40% LEL, Channel 2 point 1 = 10 ppm, and Channel 2 point 2 = 20 ppm. Refer
to Section ‘4.2.4: Viewing and setting alarm levels (points)’ when setting alarm levels.
2. Set Relay Options: Each alarm relay can be set up for energized or de-energized and latching or
non-latching. Configure alarm relays options as desired. See ‘4.2.5 Setting Relay options’.
3. Relay Assignment: There are (3) alarm relays and (2) channels. Assign alarm relays to channels as
desired, e.g.
o
Alarm relay 1 assigned to Channel 1 Point 1 (20% LEL)
o
Alarm relay 2 assigned to Channel 2 Point 1 (10 ppm)
o
Alarm relay 3 assigned to Channel 1 Point 2 (40% LEL)
o
Alarm relay 3 assigned to Channel 2 Point 2 (20 ppm)
