Installing Repeaters
+
The Display Module (if used) must be installed be
-
fore the Repeaters.
Repeaters can be wall mounted, or flush mounted to an
ave
®
BL08 outlet box (or similar).
Work carefully through the following steps.
1. Lay the connection cables (refer to “Connecting
Repeaters”).
2. Remove the screws (4) and open the Control panel.
3. Take out the bag 22 containing the Repeater panel
Keys (Access Level 2).
4. If necessary, install the Display Module as descri
-
bed in the “Display Module” section.
5. If you are flush mounting the Repeater, go to step
7. If you are wall mounting the Repeater, drill the
anchor screw holes 33.
6. Pull the wires through the wire entry 34, then, using
the anchor screws, secure the Repeater to the wall.
7. Complete the connections to the terminal board 77
of the RS485 Interface (part nr. 35), as described in
the “Connecting Repeaters” section.
8. Using the jumpers 76 of the RS485 (part nr. 35), set
the Repeater Address, as per the following Table:
Repeater nr.
Jumpers 76
12
1ININ
2 OUT IN
3 IN OUT
4 OUT OUT
9. After power up, set the Address of the Display Mo
-
dule (if installed), as described in the “Display Mo
-
dule” section under “PROGRAMMING FROM THE
CONTROL PANEL”.
Installing the Control panel
Work carefully through the following steps (see the Fi
-
gures on pages 10, 12 and 14).
1. Remove the screws (4) and open the Control panel.
2. Drill the anchor screw holes 9.
!
Check for water pipes and electrical wiring be
-
fore drilling.
3. If necessary, using a hammer or similar tool, remo
-
ve the surface conduit wire knockouts 1.
+
The cable conduit union with the case must be se
-
cured by HB Flame Class (or higher) lock nuts.
4. Pull the wires through the chased wire entry 12
then, using the anchor screws, secure the backpla
-
te to the wall.
Description of the Terminals
This section describes the Control panel terminals.
n Main Board and Expander Board terminals
[Z1] ... [Z8] Supervised/Bypassable detection zo-
nes. Detection device terminals for Fire detectors, Call
points, Gas detectors, etc.
The Control panel will consider the zone:
Ø Open when the voltage is between 27.6 V and
26.31 V;
Ø In Standby when the voltage is between 26.31 V and
17.15 V;
Ø In Alarm when the voltage is between 17.15 V and
2.82 V;
Ø
Shorted when the voltage is between 2.82 V and
0V.
If the Call point priority option has been enabled (refer
to “PROGRAMMING FROM A PC”), the Control panel
will distinguish between Alarms generated by Detectors
and Alarms generated by Manual Call Point, as follows:
Ø
Detector Alarm when the voltage is between
17.15 V and 13.15 V;
Ø
Call point Alarm when the voltage is between
13.15 V and 2.82 V.
The status thresholds can be programmed individually
for each zone, in this way, it will be possible to compen
-
sate for voltage drops caused by the connections.
Up to 30 devices can be connected to each zone.
One 4-20 mA Gas detector can be connected to zone
Z1 of the Main Board and the Expander Module, as de
-
scribed in the “Connecting Gas Detectors” paragraph.
