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
- Mount device or module per manual clearances and height tables.
- Wire loop, bus, or enroll wireless ID as applicable.
- Program zone type, partition, siren delay, and device options in panel software.
- Run placement test (wireless) or megohm/loop test (wired) before closing cover.
- Walk-test sensor/siren or verify module output/supervision.
- 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.
