AE Silenceable Activated Extinguishment Output
This Output is for “Activated Extinguishment” signal.
Operating principles
Ø
Standby status: negative pull-down to 0 V on the [+]
terminal; positive pull-up to 27.6 V on the [–] terminal.
Ø
Activated status: positive pull-up to 27.6 V on the [+]
terminal; negative pull-down to 0 V on the [–] terminal.
+
For correct operation of the output, the EOL resistor
must be connected as shown in Figure 19 on page 33.
Up to 1 A can circulate on the AE Output.
+
In the event of shorted or open connections on the
AE Output, the output will not be activated.
PE Postpone Extinguishment. This output goes to ne
-
gative when the Inhibit Extinguishment Input is activated.
Up to 0.1 A can circulate on the PE Output.
The System Wiring
+
Use shielded cable only for all connections, with
one end of the shield connected to the Control pa
-
nel negative terminal and the other left free.
!
High Voltage leads (230 V) must be bunched se-
parately from Low Voltage leads (24 V). All le-
ads must be bunched in such a way as to avoid
contact with other wiring and components.
n Connecting Fire Detectors
This Control panel supports Conventional Fire Detec-
tors (i.e. devices which resemble the operating mode of
open contacts during standby status, and resistors du-
ring Alarm status).
+
DO NOT connect more than 30 devices to each
zone.
Connect Conventional Fire Detectors as per Figure 14.
Operating principles
Ø
Terminals L1 and L2, respectively, the power input
and output terminals of the detector (these terminals
connect when the detector is attached to its base,
and disconnect when it is removed);
Ø
terminal L — the negative power terminal of the de
-
tector;
Ø
EOL resistor 109 — to be connected between termi
-
nal L1 and terminal L of the last detector. The EOL
resistor allows the system to check continuity and
detect short-circuits;
Ø
Diodes 110 — necessary when the Bypass Missing
Detectors option is enabled (further details in the fol
-
lowing paragraph).
+
Connect any unused zone terminals to negative
with a 3900 ohm, 1/4 W resistor.
The Control panel and Expander Modules provide suffi
-
cient 3900 ohm, 1/4 W resistors to balance their zones.
This Control panel also accepts Fire detectors with Nor
-
mally-Open Alarm Outputs, as shown in Figure 15.
Connect a 680 ohm (111) resistor in series to the Nor-
mally-Open contact, then connect the series of the
contact with the resistor and the Normally-Open contact
to the zone terminal.
