Pre-Installation
Checklist
This checklist is intended to
provide reminders before the installation process begins, as well
as when it is complete.
- Daisy chain the MI link
The MI link must be wired in a daisy chain
configuration.
- Terminate the MI link
The MI link must be terminated at the last MI using
an LT-1 link terminator (provided in the processor box)
if the link runs farther than 50 feet. A 120 ohm resistor
may be used across terminals 3 and 4 if an LT-1 isn't
available.
- Terminal 2 is unused for
external MIs
Do not connect terminal 2 between external MIs and
the Processor. All external MIs have their own integral
power supply and do not need to be powered from the
Processor.
- Daisy chain the D48 link
The D48 link must be wired in a daisy chain
configuration.
- Terminate the D48 link
The D48 link must be terminated at the processor and
at the last D48 using an LT-1 link terminator (provided
in the processor box) if the link runs farther than 50
feet. A 120 ohm resistor may be used across terminals 3
and 4 if an LT-1 isn't available.
- Terminal 2 is unused for
external D48s
Do not connect terminal 2 between external D48s and
the Processor. All external D48s use the power supply
provided in the HWI-ENC-LV17 and do not need to be
powered from the Processor. Note that a D48 that is in an
HWI-ENC-LV32 with a processor is not considered an "external"
D48, and thus should have terminal 2 connected.
- Daisy chain the GRAFIK Eye
link
The GRAFIK Eye link must be wired in a daisy chain
configuration.
- Terminal 2 is unused for
the GRAFIK Eye link
Do not connect terminal 2 between GRAFIK Eyes and the
Processor. All GRAFIK Eyes have their own internal power
supply and do not need to be powered from the Processor.
If you are using GRAFIK Eye accessory controls, be sure
to follow the low-voltage wiring instructions packaged
with the units
- Daisy chain the Inter-Processor
link
The Inter-Processor link must be wired in a daisy
chain configuration. A 120 ohm resistor may be used
across terminals 3 and 4 if an LT-1 isn't available.
- Terminate the Inter-Processor
link
The Inter-Processor link must be terminated at the
first and last processors using an LT-1 link terminator (provided
in the processor box) if the link runs farther than 50
feet. A 120 ohm resistor may be used across terminals 3
and 4 if an LT-1 isn't available.
- Terminal 2 is unused for
the Inter-Processor link
Do not connect terminal 2 between Processors. All
Processors have their own internal power supply.
- Take your CCOs out of
manual mode
CCOs will not respond to the keypad link
communications if left in manual mode. Manual mode is set
by using the Mode dipswitch on the CCO.
- Remove bypass jumpers
Remove the bypass jumpers from the RPM terminal
blocks after verifying the system high-voltage wiring.
- Leave a copy of the latest
database at the job site
You can store a copy of the job database on a 3 ½"
floppy disk and place it in the holder on the back of the
PNL8 cover. We strongly encourage you to keep a copy of
the database at your place of business as well.
- Install 4R and 4M modules
in the bottom locations of a remote power panel
This is the optimum configuration for heat
dissipation, but it is not necessary.
