Overview
The DSC PowerSeries PC1864 is a hardwired burglary control panel from the PC1616/PC1832/PC1864 family (firmware v4.5 and higher in this documentation set). It is aimed at small to mid-size residential and light commercial installs where you need a proven Keybus panel with room to grow through zone expanders, wireless receivers, and IP/cellular communicators—not a touchscreen-all-in-one platform.

What This Panel Does Well
The PC1864 sits at the center of a traditional DSC PowerSeries install: it supervises wired loops and wireless transmitters, drives bell/siren output and PGM relays, reports to a central station over phone, IP, or cellular modules, and supports up to eight partitions for common split residential or small business layouts.
Eight on-board zones cover many installs; adding PC5108 expanders brings the panel to 64 hardwired zones. A RF5132-433 wireless receiver (v5.1+) or RFK55xx-433 keypad with integrated receiver adds up to 32 wireless zones without changing the panel itself.
Programming is done at the keypad with installer code [*, 8, installer code] or remotely through DLS once the user enables the DLS service window. End users arm, disarm, bypass, and read troubles from PK-series LED keypads, PK5500/RFK5500 LCD keypads, or legacy LCD5511/LED5511Z fixed-message keypads.
Before You Service or Replace One
Confirm these details before quoting parts, programming, or a swap:
- Panel family and firmware — Manuals cover PC1616/1832/1864 v4.5+; programming worksheets and feature limits differ by version.
- Region — NA vs EU install manuals and transformer models differ (e.g., PTD1640U-CC for plug-in NA installs).
- Expansion already in place — PC5108 v1 and v2 must not be mixed on the same panel; jumper settings assign zone banks.
- Wireless generation — 433 MHz PowerSeries wireless; CO wireless requires RF5132 v5.1+ or RFK55xx-433 v1.2+ with WS4913 detectors.
- Communicator path — Phone (RJ-31X), T-Link TL-250/TL-300, TL260GS, GS2060, and related modules each have their own wiring and programming sections.
- Listed install type — UL/ULC burglary, fire, and SIA CP-01 false-alarm reduction each impose specific programming defaults (entry/exit limits, EOL types, bell timeout, etc.).

Error Codes
On PC1864 systems, trouble conditions appear at the keypad as a flashing Trouble or System light with a beep every 10 seconds. Press [*, 2] to open the trouble menu; LED keypads show trouble numbers 1–8; LCD keypads scroll descriptions. Press [#] to silence beeps without clearing the underlying fault.
Press [1] when Service Required is shown to view sub-codes 1–8.
Main Trouble Menu
| # | Display | Meaning | Typical cause |
|---|---|---|---|
| 1 | Service Required | One or more internal service faults | See sub-codes below; call your alarm company |
| 2 | Loss of AC Power / AC Trouble | Primary AC missing at panel | Tripped breaker, bad transformer, switched outlet |
| 3 | Telephone Line Fault | Panel cannot see phone line voltage | Line disconnected, RJ-31X wiring, off-hook device |
| 4 | Failure to Communicate (FTC) | Panel could not reach central station | Wrong phone/IP/cellular path, format, or account |
| 5 | Sensor / Zone Fault | Supervisory fault on one or more zones | Open loop, wrong EOL, wireless supervision loss |
| 6 | Sensor / Zone Tamper | Tamper on zone or device | Cover open, broken wire, wireless tamper |
| 7 | Sensor / Zone Low Battery | Low battery on wireless device | Transmitter, wireless key, or keypad battery |
| 8 | Loss of Time & Date | Clock lost after full power loss | Reprogram time/date after AC and battery restored |

| 4 | System Tamper | Panel or module tamper input open |
| 5 | Module Supervision | Keybus module not communicating (wrong slot, removed module, needs rescan) |

Notes for Installers
- New battery: Allow up to one hour of charging before expecting trouble 1-1 to clear.
- Unused bell output: Install a 1000 Ω resistor across Bell+ and Bell− or a bell trouble remains.
- Module supervision reset: Enter programming section
[902], press[*], wait one minute for Keybus rescan; use[903]to identify modules. - Reporting vs keypad: Central station may receive Contact ID or SIA trouble/restoral codes (e.g., AT/EJ for module trouble, YK for phone restore) in addition to keypad display—see Appendix A in the install manual for code mapping.
