Connecting outputs
Control panel outputs are shown in the table below.
Table 16: Control panel outputs
Description Supervision
Used to supply power to auxiliary equipment. The
output can be configured as resettable and to shut
down when there is no mains power.
Short circuit, voltage
level
Configurable outputs (the default configuration is
sounder output). The number of configurable
outputs depends on the control panel model (see
the topic below).
Note: These outputs comply with EN 54-13
requirements when configured as Class A outputs.
Short circuit, open
circuit
This fire output is activated when the control panel
is in alarm status.
Note: This output does not comply with EN 54-13
requirements.
Short circuit, open
circuit
This relay output is activated (a short circuit
between the common (C) and normally open (NO)
terminals of the relay) when there is an alarm.
Not supervised
This fault output is activated when the control
panel is not reporting a fault.
Note: This output complies with EN 54-13
requirements when the 2010-FS-EOL end-of-line
device is installed.
Short circuit, open
circuit
The fault relay output is activated (a short circuit
between the common (C) and normally open (NO)
terminals of the relay) when there is no fault.
Not supervised
[1] For activation voltage, see Chapter 5 “Technical specifications” on page 137.
Output termination
All outputs (except the 24V AUX output) must be terminated. Termination
requirements are shown in the table below.
Table 17: Termination requirements
Output termination
Class B (for typical installations)
15 kΩ
EN 54-13 installations) 4.7 kΩ [1]
[1] Installed in parallel with one of the output terminals. See Figure 15 on page 33.
If an output is not used, the 15 kΩ end-of-line resistor must be installed across
the unused terminals to avoid an open circuit fault on the output. Unused outputs
must be configured as Class B.
