5.2.5.1 Connecting the battery box to
the panel PSU
1. Run a suitable 4-core shielded cable between
the panel and the battery box.
2. Label each core appropriately (BAT+, BAT-,
THERM, THERM).
3. Connect the negative battery conductor to the
“Batt -” [battery negative] terminal and connect
the positive battery conductor to the “Batt +”
[battery positive] terminal. Both terminals are
situated on the panel chassis.
4. Connect the Thermistor leads to the two
terminals marked “Therm” on the panel chassis.
5. Warning: Do not connect the leads to the battery
at this stage. Connection of the batteries will
power up the panel even if the mains supply is
off.
5.2.6
Installation and connection of
the C1631 Repeater Interface
Warning: Observe anti-static precautions
The C1631 interface board is not provided as
standard with the panel. It is included in the spares
kit of the repeater panel, to be fitted in the main fire
alarm panel when required.
1. Ensure that the panel and repeaters are
powered down and the main and standby
supplies are disconnected.
2. On the fire alarm panel remove the jumper link
at J22 (adjacent to J9) and fit a C1631
repeater interface to connectors J13 and J9 on
the right-hand side of the C1627 motherboard.
The board should be held in place by the
12mm high plastic spacer provided. See
Figure 10.
3. The Repeater is supplied with the C1631
Interface Board fitted.
4. Connect the RS485 data cable as shown in
Figure 3.
5. Connect the Aux 24Vdc supply from the panel
to the repeater. You can use two cores in the
data cable for this purpose only if the voltage
drop between the panel and repeater is not
more than 2Vdc.
Notes:
One repeater will draw up to 75mA which means
that the total resistance of the cable should not
exceed 24 Ohms (12 Ohms in each core). The
T1216W-C Application Guide lists cable types with
their nominal DC resistance.
If more than one repeater is required or the cable
resistance is too great, then data cable is
unsuitable for supplying power and a separate
suitable 2-core cable must be used.
Use only Plenum rated screened data cable with at
least three core-pairs to accommodate repeater
communication & Muster Interface options. 4 pairs
will be required if power is also being provided
(subject to the limitations described above).
Connect the cable screen to earth at the fire alarm
panel and the repeaters.
5.2.7 Installation and connection of the
C1665 Muster Interface
Warning: Observe anti-static precautions
The C1665 interface board is not provided as
standard with the panel. It is an optional item that
can be ordered separately and used with repeaters
to provide Muster Alarm control from repeater
panels.
1. Ensure that the panel and repeaters are
powered down and the main and standby
supplies are disconnected.
2. On the C1627 motherboard in the fire alarm
panel and each repeater, identify link J23 and
connector J2 which are located on the left
hand side of the motherboard.
3. Remove link J23 and carefully plug the C1665
PCB into connectors J2 and J23.
4. Connect the field cable as shown in Figure 4.
5. Connect 2 off 3K9 monitoring resistors to the
C1665 in the last repeater as shown in Figure
4. [The resistors are supplied in the Muster
Interface fixing kit].
6. On the fire alarm panel display PCB fit link J2
to the lower position for Muster operation
Note:
Use three cores of the RS485 screened data
cable.
