Keybus Terminals – AUX+, AUX-, YEL, GRN

The Keybus is used by the panel to communicate with mod-
ules and vice versa. Each module has four Keybus terminals
that must be connected to the four Keybus terminals on the
panel. For more information, see section

2.3 “Keybus Opera-

tion and Wiring”.

Programmable Output Terminals – PGM1 and PGM2

Each PGM output is designed so that when activated by the
panel, the terminal will switch to ground.

PGM1 can sink up to 300mA of
current. Connect the positive
side of the LED or buzzer to
AUX+, the negative side to
PGM1. If more than 300 mA of
current are required, a relay
must be used. Please study
PGM wiring in the accompany-
ing diagram.
PGM2 operates similarly to
PGM1. However, PGM2 can
only sink up to 50mA of cur-
rent. For a list of the program-
mable output options, see
section 5.11

“PGM Output

Options” on page 20.

Zone Input Terminals – Z1 to Z6

Each detection device must be connected to a zone on the
control panel. We suggest that one detection device be con-
nected to each zone; wiring multiple detection devices to a
single zone, however, is possible. For zone wiring specifics,
please see section 2.8

“Zone Wiring” on page 5.

Telephone Connection Terminals – TIP, RING, T-1, R-1

If a telephone line is required for central station communica-
tion or downloading, connect an RJ-31X telephone jack in the
following manner:

Connect the PC5008 and modules which use the telephone
line(s) in the following order:

For example, if you are installing a PC5008 with an Escort5580
and a PC5928 Intercom module, connect the incoming line to
the control panel, then to the Escort5580 and then to the
PC5928 Intercom. Next, connect the PC5928 to the house
telephones.

NOTE: For proper operation, no other telephone equipment
should be connected between the control panel and the tele-
phone company facilities. Do not connect the alarm panel com-

municator to telephone lines intended for use with a fax
machine. These lines may incorporate a voice filter which dis-
connects the line if anything other than fax signals are
detected, resulting in incomplete transmissions.

2.3

Keybus Operation and Wiring

The Keybus is used by the panel to communicate with all con-
nected modules and vice versa. The red (AUX+) and black
(AUX-) terminals are used to provide power, while the yellow
(YEL) and green (GRN) terminals are clock and data respec-
tively.

NOTE: The four Keybus terminals of the panel must be con-
nected to the four Keybus terminals or wires of all modules.

The following restrictions apply to Keybus wiring:

•

Keybus should be run in minimum 22 gauge quad
(0.5mm); two pair twist is preferred.

•

The modules should be home-run to the panel but can be
connected in series or T-tapped.

•

Any module can be connected anywhere along the Key-
bus. You do not need to run a separate Keybus wire for
keypads, etc.

•

No module can be more than 1,000'/305m (in wire length)
from the panel.

•

Shielded wire should not be used.

Example of Keybus Wiring

NOTE:
Module (A) is correctly
wired within 1,000'/
305m of wire from the
panel.
Module (B) is correctly
wired within 1,000'/
305m of wire from the
panel.
Module (C) is NOT wired correctly as it is further than 1,000'/
305m from the panel, in wire distance.

Current Ratings – Modules and
Accessories

In order for the PC5008 system to operate properly, the power
output capabilities of the main control and the expansion
devices must not be exceeded. Use the data presented below
to ensure that no part of the system is overloaded and cannot
function properly.

PC5008 (12 V

)

AUX+: ........550mA: Subtract the listed rating for each key-

pad, expansion module and accessory con-
nected to AUX+ or Keybus.

BELL: .........700mA continuous rating; 3.0A short term. Avail-

able only with standby battery connected.

PC5008 Device Ratings (at 12 V

)

•

LCD5500Z Keypad: 85mA

•

PC5508Z Keypad: 75-85mA
