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, max. 18 AWG (2-wire twisted preferred)
• Do not use shielded wire
• Modules can be home run, connected in series or 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
Zone Wiring
Zones can be wired for Normally Open or Normally Closed contacts, with Single-End-of-Line (SEOL) 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

• [101]-[108] Opt [14], [15], [16] Selects Normally Closed SEOL or DEOL for on-board zones

Zone Status - Loop Resistance/Loop Status
• Fault - 0Ω (shorted wire/loop)
• Secure - 5600Ω (contact closed)
Zone Expanders
Zone expanders add zones in groups of eight to the
Alarm system. Module jumpers J1, J2, J3 are
required to assign zones to these modules. Jumper
settings for PC5108 v2 are shown here.
PC5108 1.0 supports first 32 zones only
PC5700 enrolls as two modules
Do NOT use PC5108 v1 and PC5108 v2 on the
same panel.
Bell Wiring
These terminals supply 700mA of current at 12VDC for commercial installations and 11.1-12.6VDC for residential installations (e.g.,
DSC SD-15 WULF). To comply with NFPA 72 Temporal Three Pattern requirements, Program [013] Opt [8] must be ON. Note that
Steady, Pulsed alarms are also supported.
The Bell output is supervised and power limited by 2A PTC. If unused, connect a 1000Ω resistor across Bell+ and Bell- to prevent the
panel from displaying a trouble. See [*][2].
