Connecting standard supervised outputs
All standard supervised outputs require a 15 kΩ, 5%, 1/4 W end-of-line resistor
as termination for proper detection of wiring problems (open or short circuit). If an
output is not used, the end-of-line resistor must be installed across the unused
terminals.

output
Standard supervised outputs provide −11 VDC in standby and +24 VDC when
active (nominal values). See Chapter 5 “Technical specifications” on page 79 for
the details on the maximum current rating.
Note: Standard supervised outputs are polarity sensitive. Observe polarity or
install a 1N4007 diode or equivalent to avoid inverted activation issues.
Connecting the extinguishing actuator output
Note: Observe the polarity of the extinguishing actuator output to ensure proper
operation.
WARNING: Risk of death or serious injury. Test the line supervision (for open
and short circuit faults) and the activation function before connecting the
extinguishing agent to the actuator.
The extinguishing actuator output is the most critical output of the system, as it
controls the release of the extinguishing agent into the extinguishing area.
A special end-of-line circuit (the 2010-1EXT-EOL board) is required for proper
operation so that the wiring to the extinguishing agent actuator is supervised.
Note: To ensure reliable operation, locate the end-of-line board as close as
possible to the extinguishing actuator device.
