Keybus Terminals - RED, BLK, YEL, GRN
The Keybus is used by the panel to communicate with mod-
ules and by modules to communicate with the panel. Each
module has four Keybus terminals that must be connected to
the four Keybus terminals on the panel.

Programmable Outputs - PGM1 to PGM4
Each PGM output is designed so that when activated by the
panel, the terminal will switch to ground
PGM1, PGM3, and PGM4 can each sink up to 50 mA of cur-
rent. These PGMs can be used to activate LEDs or a small
buzzer. Connect the positive side of the LED or buzzer to
AUX+, the negative side to the PGM.
PGM2 is a high current output (300mA) and operates simi-
larly to PGM1. If more than 300 mA of current is required, a
relay must be used. Refer to the diagram. PGM2 can also be
configured as an input.

Zone Input Terminals - Z1 to Z8
Each detection device must be connected to a zone terminal
on the system. It is suggested that each zone have one
detection device however it is possible to wire multiple detec-
tion devices to the same zone.
For zone wiring details, see section 2.10 ’Zone Wiring’ .

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 jack in the following
manner:

Connect the PC1616/PC1832/PC1864 and modules that
use the telephone line(s) in the following order:

NOTE:

Ensure that all plugs and jacks meet the dimension,

tolerance and metallic plating requirements of 47 C.F.R. Part
68, SubPart F. For proper operation there must be no other
telephone equipment connected between the control panel
and the telephone company facilities.

NOTE:

Do not connect the alarm panel communicator to

telephone lines intended for use with a FAX machine. These
lines may incorporate a voice filter which disconnects the line
if anything other than FAX signals are detected, resulting in
incomplete transmissions

2.3 Wire Routing for Power & Non-Power Limited

All wiring entry points are designated by the arrows. All cir-
cuits are classified UL installation power limited except for
the battery leads which are not power limited.

A minimum ¼” (6.4mm) separation must be maintained at all
points between power limited and non-power limited wiring
and connections.

NOTE:

Wire entry for power limited wiring must be sepa-

rated by a different entry access from non-power limited wir-
ing.

2.4 Keybus Operation and Wiring

The Keybus is used by the panel to communicate with all
modules connected and by the modules to talk to the panel.
The RED and BLK terminals are used to provide power while
YEL and GRN are clock and data.
The 4 Keybus terminals of the panel must be connected to
the 4 Keybus terminals or wires of all modules.
The following conditions apply:

• Keybus should be run with minimum 22 gauge quad

(0.5mm), two pair twisted preferred

• The modules can be home run to the panel, connected in

series or can be T-tapped

• Any module can be connected anywhere along the Key-

bus, you do not need a separate Keybus wire run for key-
pads, zone expanders etc.

• No module can be more than 1,000'/305m (in wire length)

from the panel

NOTE:

Shielded wire should not be used for Keybus wiring.

Example of Keybus Wiring
Module (A) is  wired correctly
as it is within 1,000'/305m of
the  panel,  in  wire  distance.
Module (B) is  wired correctly
as it is within 1,000'/305m of
the  panel,  in  wire  distance.
Module (C) is NOT wired cor-
rectly  as  it  is  further  than
1,000'/305m from the panel, in wire distance.

2.5 Current Ratings - Modules & Accessories

In order for the PC1616/PC1832/PC1864 system to operate
properly, the power output capabilities of the main control
and expansion devices must not be exceeded. Use the data
presented below to ensure that no part of the system is over-
loaded and cannot function properly.
