Wiring Requirements
P4
VESDA
RS232 port, power limited and supervised
VESDA High Level Interface (HLI) P/N
68-023 and 68-517 connection point
Intelligently links Xtralis VESDA detectors
to the Cheetah Xi by zone number. Does
not require SLC address
HLI must be located in the same room as
the panel and be located within 20 ft.
(6.1m).
68-023 and 68-517 includes a 20 ft. (6.1m)
RS232 cable P/N 02-15802 for connection
to the Cheetah Xi controller P4. Cable must
be in conduit or equivalently protected
against mechanical injury.
HLI must be powered from the Cheetah Xi
auxiliary power outputs or a ground fault
condition could occur.
P5
Peripherals
(232)
RS232 port, power limited and supervised
Interface point for Fike Guard voice
evacuation system
C-Linx connection point for programming
RS485 peripheral devices
Fike Guard voice evacuation system must
be installed in same room as the Cheetah Xi
panel within 50 ft. ( 15m) maximum
P6
DACT
(+ -)
Power limited and supervised
Interface point for Digital Alarm
Communicator Transmitter (Point ID
communication)
DACT can be mounted inside the panel
or external in a separate enclosure
Terminal blocks accept 12 – 24 AWG
Peripherals
(485)
(shld,+ , -)
Power limited and supervised
Connects to RS485 peripheral devices
31 peripheral devices maximum
Typical circuit voltage will vary between 0
– 1 VDC. It should never be a constant
voltage or 0 VDC
Peripheral devices must be configured as
supervised if 2-way communication is
required
RS485 wiring: Belden 9841 or equal. Use
Belden 82841, 82842, or 89841 for plenum
applications
Maximum wire length of 4000 ft. (1219m),
9600 bps, 5 VDC, 1mA
Maximum wire impedance 110
Ω
Maximum wire capacitance 0.05uF

termination resistor is required on the
last device on circuit, P/N 02-2519 (supplied
with each device)
T-tapping of circuit is NOT allowed
Terminal blocks accept 12 – 24 AWG
P7
Resettable
Aux Out (+, -,
