Hardware Installation - DSC PC1832 Reference Manual

Begin the installation by mounting the cabinet in a dry protected area with access to unswitched AC power. Install Hardware in the sequence
indicated below. Do NOT apply power until installation is complete.
NOTE: All wiring entry points are designated by arrows. All circuits are classified UL power limited except for the battery leads. Mini-
mum 1/4" (6.4mm) separation must be maintained at all points between power limited and non-power limited wiring and connections.
1. Keybus Wiring
The 4-wire Keybus (red, black, yellow and green) is the communication connection between the control panel and all modules.
The 4 Keybus terminals of all modules must be connected to the 4 KEYBUS terminals of the main control panel.
The following rules must be followed when wiring the Keybus:
• Minimum 22 AWG wire, maximum 18 AWG (2-wire twisted pre-
ferred
• Do NOT use shielded wire
• Modules can be home run, connected in series or can be T-
tapped provided that the maximum wire distance from the control
panel to any module does not exceed 1,000 feet (305m)
• No more than 3,000 feet (915m) of wire can be used in total
2. Zone Wiring
Zones can be wired for Normally Open, Normally Closed Contacts
with Single-end-of-line (SEOL) resistors or Double End-of-Line
(DEOL) resistors. Observe the following guidelines
• For UL Listed Installations use SEOL or DEOL only.
• Minimum 22 AWG wire, maximum 18 AWG
• Do NOT use shielded wire
• Wire run resistance shall not exceed 100
below:
• Section [001-004] Selects Zone Definition
• Section [013] Opt [1] Selects Normally Closed or EOL resistors
• Section [013] Opt [2] Selects Single EOL or Double EOL resis-
tors.

Loop Resistance
- 0Ω (shorted wire/loop)
- 5600Ω (contact closed)
- infinite (broken wire, open)
- 11,200Ω (contact open)
3. Bell Wiring
These terminals supply 700mA of current at 12V
installations and 11.1-12.6 V
SD-15 WULF). To comply with NFPA 72 Temporal Three Pattern
requirements:
Program Section [013] Opt [8] ON.
The Bell output is supervised and power limited. If unused, connect a
1000Ω resistor across Bell+ and Bell- to prevent the panel from dis-
playing a trouble. See [,][2].
