What this device does in the system

Provides audible/visual alarm annunciation when the panel enters alarm — must be enrolled and supervised like any other wireless or bus device.

Before you install or replace one

• Confirm exact model number on the label matches the install manual.
• Verify host panel or system family — Keybus, Corbus, Combus, PowerG, MX, or 433 MHz are not interchangeable.
• Check device limits on the panel/receiver before adding zones, sirens, or credentials.
• Include current draw in power budget calculations for modules, receivers, and keypads.
• For wireless: test RF at the mounted location, not only on the bench.

Pre-install checklist

• Match SKU to host system family and region (NA/EU frequency suffixes).
• Plan mounting location (wireless: signal; PIR: coverage; sirens: audibility; modules: bus homerun).
• Reserve panel zone/device slots and power budget.
• Confirm monitoring account accepts device type (fire/CO devices: fire account where required).
• Have installer code and DLS access ready for enrollment-heavy platforms.

Typical install sequence

1. Mount device or module per manual clearances and height tables.
2. Wire loop, bus, or enroll wireless ID as applicable.
3. Program zone type, partition, siren delay, and device options in panel software.
4. Run placement test (wireless) or megohm/loop test (wired) before closing cover.
5. Walk-test sensor/siren or verify module output/supervision.
6. Document location and zone/device number for end-user and central station.

PG9911 outdoor mount

• Use weatherproof mounting location with manual-specified tilt for strobe visibility.
• Confirm PG9911 SKU for outdoor — PG9901 is indoor-only.
• Test siren volume and strobe from property line where AHJ requires audibility/visibility.
