DSC PG9911B PowerG Outdoor Siren and Strobe with Battery

The DSC PG9911B adds a strong exterior notification point to a compatible PowerG system. Its 110 dB siren and programmable strobe can make an alarm event difficult to miss outside the property, while optional entry and exit beeps provide system feedback without requiring a signal cable to the siren location.

The IP55 housing is designed for outdoor exposure from approximately -27 to 158 F. An included DSC A-size lithium battery pack supports up to eight years of typical use, and the device reports tamper, low-battery, and supervision conditions to the panel. Programmable strobe timing and siren-active indication allow the final behavior to match the system design.

Homes and businesses can both benefit from an exterior sounder when it is placed where the alarm can be heard and seen without creating unnecessary exposure or service difficulty. Allied can integrate the siren with the property’s security equipment, confirm the programmed event types, and test both local output and monitored reporting before handoff.
