Intrusion Detection Zone Layout

ANSI/SIA CP-01 · UL 681 · Zone Schedule & Panel Sizing

When to use: Use this tool when laying out a burglar/intrusion alarm system. Define each detection zone, assign sensors, and the tool totals coverage area and panel points used, then checks them against panel capacity. It also runs an ANSI/SIA CP-01 false-alarm-reduction checklist — flagging interior motion zones that should be cross-zoned. Coverage areas are nominal estimates for planning, not a substitute for a manufacturer site survey.

ANSI/SIA CP-01 Checklist
0/7
False Alarm Reduction — verify each programmable feature in the panel.
⚠ Only one interior motion zone defined — CP-01 cross-zoning needs two interior detectors that trip in sequence. Add a second interior zone.
Entry/exit delays are programmable
Exit 45–60 s typical; entry delay set per AHJ.
Abort window present (≥15 s)
Allows user to cancel before alarm transmits.
Cross-zoning / sequential verification on non-perimeter
FLAG: single interior PIR zone — add a second interior zone to cross-zone.
Swinger / auto shutdown after ~2 trips
Faulty zone locks out after 2 trips per arming cycle.
Alarm transmission delay configured
Brief delay before signaling central station.
Duress / panic feature programmed
24-hour silent duress code or button.
Exit-error & recent-closing features enabled
Distinguishes faulty exit from intrusion within ~2 min of arming.
⚠ 7 item(s) unverified
