Overview

IQ Pro and IQ Pro P are hybrid security platforms with partitioned operation, PowerG wireless support, and multiple user interface paths.

Official source

Platform characteristics

  • Supports HS2LCD keypad interfaces
  • Supports PowerG PG wireless devices
  • Supports IQ Remote user interfaces
  • Supports partition-based operation for multi-area sites

Service perspective

Plan keypad and IQ Remote layout per partition so operators always have local status and arming control in assigned areas.

Troubleshooting

Interface parity checks

  • Confirm trouble state consistency between HS2LCD and IQ Remote displays.
  • If states differ, verify partition assignment and panel sync.

PowerG troubleshooting

  • Recheck enrollment and signal path for PG sensors.
  • Validate final mounted location behavior, not only bench enrollment.

Partition behavior checks

  • Confirm users, keypads, and remotes are mapped to intended partitions.
  • Validate arming/disarming permissions per partition.
  • Single-partition sites: all keypads may show global status; multi-partition sites require partition-select on HS2LCD before arming.

Testing before handoff

  • Run walk test and verify PG device supervision on each partition.
  • Test IQ Remote arming/disarming on assigned partition only.
  • Confirm Alarm.com mobile app (if enabled) is not used on UL/ULC listed fire installs unless explicitly approved.

Communication checks

  • Clear local trouble first.
  • Re-run path test and verify report transmission end-to-end.

Installation Notes

Suggested commissioning sequence

  1. Mount panel and establish baseline power — verify AC and battery charge.
  2. Add HS2LCD keypads on Corbus; assign unique addresses; confirm [*, 2] trouble scroll.
  3. Enroll PowerG transceiver keypads (HS2LCDRF/WF) before remote PG sensors.
  4. Enroll PowerG PG sensors and sirens; run placement test at final mount locations.
  5. Add IQ Remote devices; map each to correct partition; test arming scope.
  6. Program partitions, user codes, and reporting path in DLS/dealer software.
  7. Complete walk test, bell/siren test, and central-station communication test.

Corbus wiring reminders

  • Homerun +/-, Y, G — no T-taps on Corbus branches.
  • Reserve AUX budget for all HS2LCD and expansion modules before power-up.
  • UL fire listed installs: use HS2LCD (non-P variant) where manual requires.

Operational check before handoff

  • Trouble-free on HS2LCD and IQ Remote for assigned partitions
  • Arming/disarming verified per partition and user code
  • End-user shown [*][2] trouble path on primary keypad

FAQs

What is the difference between IQ Pro and IQ Pro P?

Both support HS2LCD, PowerG, IQ Remote, and partitions — use model-specific user documentation for SKU limits.

Where do I read trouble conditions?

HS2LCD keypads ([*][2]) and IQ Remote device icons (Open, Tampered, Unreachable, Not Networked).

Are partitions supported?

Yes — assign keypads, IQ Remotes, and sensors to partitions before handoff.

Can IQ Remote arm a different partition than the keypad?

IQ Remote is partition-scoped — verify assignment matches user expectations in multi-partition sites.

Is Alarm.com required?

Many deployments use Alarm.com for remote app access — verify account provisioning with dealer.

Which wireless generation?

PowerG — not legacy 433 MHz PowerSeries wireless.
