Figure 4: Sample Power Requirement Calculations
Power required by devices connected to control panel's
auxiliary output must not exceed the auxiliary output's limit:
(A) + (B) + (C) + (D) + (E) + (F) + (G) = 368PU<700PU = OK
15m (50ft)
APR3-PRT1
(A) = 40PU
15m (50ft)
APR3-ZX8
(B) = 28PU
30m (100ft)
As indicated in Table 2 on
page 4, this run of wire can
support 700PU. Total PU on
this run of wire:
(A) 40PU + (B) 28PU =
68PU<700PU = OK
290m (950ft)
DGP2-60
(C) = 30PU
305m (1000ft)
As indicated in Table 2 on
page 4, this run of wire
can support 136PU. Total
PU on this run of wire:
(A) 40PU + (C) 30PU =
70PU<136PU = OK
An LCD Keypad (80PU) can be added to the 100ft. or 300ft. wire in Figure
4, but adding an LCD Keypad to the 1000ft. wire would exceed the wire's
limits and cause devices to function at decreased capacity.

500ft. from control panel's aux. output
Therefore this run = max. 273PU
Power Supply
Do not use the same transformer for the control panel and the
external power supplies. Do not install modules more than
914m (3000ft) from the control panel.
2.12 Keypad Zone Connections
Every keypad, except Grafica, has one hardwire input terminal allowing you
to connect a detector or door contact directly to the keypad. For example, a
door contact located at the entry point of an establishment can be wired
directly to the input terminal of the entry point keypad instead of back to the
control panel.
Even with the ATZ feature enabled in the control panel, only
one device can be connected to the keypad's hardwired input
terminal. Tamper is not recognized on keypad zones. The
keypad zone follows the control panel's EOL definition.
A device connected to the keypad's input terminal must be assigned to a
zone in the control panel and the zone's parameters must be defined (see
Zone Programming on page 10). The keypad communicates the status of
the zone to the control panel via the combus. The detection device is
connected as shown in Figure 3 on page 3.
2.13 Addressable Zone Connections
The control panel includes eight hardwired input terminals for use with
traditional hardwired (non-combus) door contacts, smoke detectors and/or
motion detectors.
The control panel also supports several hardwire zone expansion modules.
Devices connected to hardwired input terminals must be assigned to a
zone and the zone's parameters must be defined (see Zone Programming
on page 10). Figure 6 shows single zone (ATZ disabled) hardwire input
terminal connections recognized by the Digiplex DGP-NE96 system. For
UL listed installations, use EOL resistor part #2011002000.
Power units required by devices
connected to a power supply do not draw
power from the control panel's auxiliary
output.
Module
2000ft. from control panel
500ft. from power supply
Therefore this run = max. 273PU
