All-purpose relay outputs (R1 – R3)
Control Unit is fitted with three all-purpose relay outputs. The outputs can operate in one of the two
statuses: as enabled or disabled (states are shown below).

Description
Additional parameters
Bi-colour green
indicator
Correct system operation – continuous light. After exceeding
warning 1 and 2 threshold – modulated light. After exceeding
alarm threshold and in case of fault – light off. Principle of
operation see figure 6.

Bi-colour
indicator red
Correct system operation – light off. After exceeding warning
1 and 2 threshold – modulated light. After exceeding alarm
threshold – continuous light. In case of fault – light off.
Principle of operation see figure 6.

Inactive
Always disabled.

WARNING 1
The output enables when warning 1 threshold exceeding is
detected at any detector. It is disabled when gas
concentration measured by all detectors is lower than
warning 1 threshold.
Enable delay
.
Disable delay.
Normally open (NO) operation logic/
normally closed (NC)
.
WARNING 2
The output enables when warning 2 threshold exceeding is
detected at any detector. It is disabled when gas
concentration measured by all detectors is lower than
warning 2 threshold.
Enable delay.
Disable delay.
Normally open (NO) operation logic/
normally closed (NC).
Alarm
The output enables when alarm threshold exceeding is
detected at any detector. It is disabled when gas
concentration measured by all detectors is lower than the
alarm threshold.
Enable delay.
Disable delay.
Normally open (NO) operation logic/
normally closed (NC).
SO copy
The output copies the status of visual indicator output.

2
Parameter enable delay and disable delay can range from 0 s ÷ 5400 s (90 min)
3
Selecting the “normally closed” option causes status change between activation and deactivation (see figure 5)
