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.

FAQs
Which panels or systems does MAXSYS Dual-Zone Bell Panel PC4702BP work with?

Can I use this on a different brand panel?

How do I test after installation?
Complete walk test, supervision test, and (for wireless) placement test at the final mounted location — bench tests miss range issues.
Indoor vs outdoor siren — can I substitute?
No — outdoor models include weather sealing and strobe; indoor models will fail outdoors and may void listing.
Siren does not sound on alarm but no trouble shows
Check bell output programming, partition assignment, and whether a silent alarm or test mode is active.
How loud should the siren be?
Follow local AHJ and install manual — outdoor sirens often require minimum dB at property line.
