[1]
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
[1]
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 109.
Output termination
All outputs (except the 24V AUX output) must be terminated. Termination
requirements are shown in the table below.
Table 12: Termination requirements
for typical installations) 15 kΩ
(for EN 54-13 installations) 4.7 kΩ [1]
[1] Installed in parallel with one of the output terminals. See Figure 13 on page 26.
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.
End-of-line components for outputs are included in the accessory kit provided
with your control panel.
Note: Output termination differs for typical and EN 54-13 installation types. Take
care to install the correct termination for your installation.
Output polarity
All outputs are polarity sensitive. Observe polarity or install a 1N4007 diode or
equivalent to avoid inverted activation issues due to reverse polarity supervision.
Connecting auxiliary equipment
Connect auxiliary equipment to 24V AUX as shown in Figure 12 on page 25.
