ChallengerPlus Installation and Quick Programming Manual
15
The installer is responsible for identifying and specifying batteries with an
operating temperature range commensurate with the specific TS1066 installation
environment; a minimum range of 0°C to +40°C is recommended.
A fuse is required in the positive lead of each battery. Each fuse must be a
3AG/3AB (6x32 mm) 8A, 250 VAC, slow blow (time lag) fuse, compliant with UL
248.14. Suitable parts include Littelfuse 0313008.HXP, Bel Fuse 3SB 8-R, and
Schurter 8020.5020.
The installer is responsible for ensuring that the specified batteries in conjunction
with the configured system load and TS1066 charger settings provide the
required system backup and recharge times.
The installer (or user) is responsible for scheduling on-going battery system
checks as required by the applicable standards and codes to ensure user safety,
battery integrity and system performance; a 3 monthly interval is suggested.
Auxiliary power terminals
Connect the + and
– auxiliary power output terminals to devices that require
12 VDC power, such as detectors. If you need more connections you can use a
TS0844 board to increase the number of terminals (see “TS0844 Power
Distribution Board
RS-485 LAN
Use 2-pair twisted shielded data cable such as Belden 8723 to connect the
Challenger panel to system devices such as RASs and DGPs.
• Connect the + terminal to the red wire. The + terminal pr12 V to LAN
devices such as RASs (within 100 m cabling distance).
• Connect the – terminal to the black wire. The – terminal provides -ve DC to
LAN devices such as RASs, and common 0 V for the RS-485 LAN.
• Connect the D+ terminal to the white wire. The D+ terminal is data positive.
• Connect the D– terminal to the green wire. The D– terminal is data negative.
• Connect the data cable shield to the LAN earth connection (Figure 5 on page
11, item 1).
The RS-485 LAN may be used to power devices up to 100 m cabling distance
from the Challenger panel.
See “Power supply to RS-485 LAN devices” on page
4 for details.
If you need more than one connection to the LAN terminals you can use a
TS0844 board to increase the number of terminals (see “TS0844 Power
Distribution Board
RS-485 LAN termination
All Challenger LAN devices (including the panel) use a 470 Ω LAN termination
resistor where required. LAN termination resistors are used to set the impedance
of the LAN to around 220 Ω in order to minimise noise. The termination resistor
may be external or onboard (devices with an onboard resistor use a link or a DIP
switch to set the LAN termination to ON).
