Overview

Alexor PC9155 is a wireless intrusion panel built around compact deployments and fast enrollment workflows.

Official source

Capacity and I/O profile

  • Wireless zones: 1 to 32
  • Auxiliary output current: 200 mA
  • On-board I/O points can be used either as:
  • Zone 33 and Zone 34 inputs, or
  • Low-current PGM outputs (50 mA)

Enrollment behavior

  • Wireless enrollment section: [804]
  • First keypad enrollment window is approximately 2 minutes after initial power-up

Signaling options

  • Optional communicator modules include TL265, TL265GS, GS2065, and GS2060 family IP/cellular modules.
  • For SIA CP-01 installations, minimum equipment is PC9155-433 control panel plus WT5500-433 keypad.
  • Optional: WT5500P-433 (prox reader), PT4 prox tags, WT4989 keys, WT4901/WT4911 sirens.

Troubleshooting

Enrollment-first approach

  • Start with keypad enrollment immediately after panel power-up.
  • If first keypad is missed, restart power and repeat within the initial 2-minute window.
  • Use [804] for wireless enrollment verification and cleanup.

Zone and I/O conflicts

  • Confirm whether onboard I/O is defined as zones 33/34 or as PGMs.
  • Resolve duplicate mappings before zone walk tests.
  • Test alarm and restore transitions for every enrolled point.

Power budget checks

  • Keep AUX draw within 200 mA.
  • For external devices, avoid sourcing power from panel AUX if startup current is unknown.

SIA deployment guardrail

For SIA-oriented deployments, verify minimum equipment set is PC9155-433 with WT5500-433 before dispatch.
