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.).

FAQs
Is the PC1864 still a supported DSC product?
Yes. DSC continues to host PC1616 documentation on the official product page and CMS download library. DSC hosts User Manual v4.5 and Installation Manual v4.5 (NA and EU). Newer revisions (v4.6, v4.7) may apply—check revision before applying region-specific listed-install rules.
How many zones does the PC1864 actually have?
Eight hardwired zones on the board. With PC5108 expanders, the panel supports up to 64 hardwired zones. Up to 32 wireless zones are available with an RF5132-433 or RFK55xx-433 receiver. Keypads can also contribute zone inputs (11 keypad zones supported system-wide).
What is the difference between PC1616, PC1832, and PC1864?
All three share the same manual family and Keybus peripherals. The PC1616 is the smallest: 6 on-board zones, 2 partitions, 48 user codes, 2 on-board PGM outputs. The PC1832 adds zones and partitions; the PC1864 is the largest in the line. Programming section numbers are shared—verify the model-specific limits in the install manual feature table before assigning zones or partitions.
Why do my manuals cover three models?
DSC publishes combined installation and user manuals for the PC1616/PC1832/PC1864 platform. Always confirm which limits apply to PC1616 specifically (zone count, partitions, user codes, PGM count).
Can I use PowerSeries Neo keypads or PowerG sensors?
No. The PC1616 is classic PowerSeries with 433 MHz DSC wireless and 4-wire Keybus. Neo HS2 keypads, PowerG receivers, and IQ ecosystem devices are a different product line.
How do I view trouble conditions?
Press **[*, 2] while disarmed. The trouble light flashes and the keypad shows trouble numbers 1–8. Press [#] to silence beeping. For Service Required, press [1]** to see sub-codes (low battery, bell fault, module supervision, etc.). See the error codes section on this product listing for the full table.
The panel shows Loss of Time & Date. Is it broken?
Not necessarily. This trouble appears after complete power loss (AC and battery removed or depleted). Restore power, wait for battery charging if needed, then reprogram time and date with **[*, 8]** on PK-series keypads or through user functions.
Why is there a bell circuit trouble with no siren connected?
The bell output is supervised. If you are not using Bell+/Bell−, install a 1000 Ω resistor across the terminals. Otherwise the panel reports trouble 1-2 indefinitely.
How many keypads can I install?
Up to eight keypads on Keybus. Total current for all modules and keypads must stay within 700 mA from the panel AUX+ output unless you add a PC5200 or PC5204 auxiliary supply.
Can one PC1616 serve multiple areas or tenants?
Yes, partially. The PC1616 supports 2 partitions with separate arming and user code assignment. It does not support eight partitions like the PC1864. Assign partition access in user code programming [*, 5, master, 98, user].
What communicator options work with the PC1616?
Common options include on-board phone dialer (RJ-31X line seizure), T-Link TL-250/TL-300 IP communicators, TL260GS Ethernet/cellular combinations, and GS2060 cellular modules—all connect via Keybus with current listed in the install manual. Programming format and account numbers are in installer sections [311]–[381] and Appendix F.
Why does the panel fail to communicate even though the phone works?
Failure to communicate (trouble 4) is not the same as a dead phone line. Check programmed phone numbers, communicator format (Contact ID, SIA, pulse), account number, handshake compatibility with the central station, and whether telephone line trouble (3) is also present. IP/cellular paths need module link status and receiver enrollment—not just panel programming.
How do I reset module supervision after swapping a PC5108 or keypad?
Enter installer programming and run section [902], press **[*], and wait one minute for the Keybus rescan. Use [903]** to verify detected modules. Wrong keypad slot assignment also causes supervision faults.
What battery size does the PC1616 need?
Use sealed lead-acid or gel batteries. Size depends on standby requirement: 4 Ah for typical UL burglary (4 hr), 7 Ah or 14 Ah for 24 hr fire or health care listed installs. Charging is 400 mA; replace every 3–5 years.
Can I replace a PC1616 with a newer panel and keep everything?
Sometimes, but not automatically. Reuse depends on matching Keybus modules, 433 MHz wireless enrollments, communicator type, and programming migration (DLS backup/restore or reprogram). Neo panels require different peripherals. Survey expanders, receivers, and communicators before quoting a upgrade.
Where is the official documentation?
DSC hosts User Manual v4.5 and Installation Manual v4.5 (NA and EU) on the official PC1616 product page. Newer revisions (v4.6, v4.7) may apply for your region.
