Supervised Wireless PowerG Outdoor Siren

Why Choose This with Smart Shield Systems

• Loud, code-aware installs: we place the siren for audibility, set event-specific tones, and program strobe timing per your preferences and local requirements.

• Signal verified on the spot: we use the siren’s link-quality LEDs and self-test before we mount it, aiming for GOOD/STRONG RF (UL/ULC: STRONG).

• Sealed and secure: we mount vertically for weatherproofing, engage double tamper (front + wall), and document battery service steps.

Frequently Asked Questions

How loud is the siren?

Specs call for ≥109–110 dB at 1 m (about 85 dB at 3 m) with a piercing sweep tone for burglary events.

What does the strobe do?

The built-in strobe pulses about once per second during alarms for visual verification outdoors.

Can I get door-chime and arming feedback outside?

Yes—entry/exit beeps and arm/disarm squawks can be enabled from the panel. We’ll set what you want.

How weatherproof is it?

The enclosure is rated IP55 (dust-protected, water-jet resistant). Proper vertical mounting maintains the seal.

What batteries does it use and how long will they last?

Two internal packs (each with two 3.6 V lithium cells) connect via a cable adapter; typical life is up to ~8 years. Your system reports low battery well in advance.

Will it work with my IQ Panel?

Yes—PowerG sirens, including PG9911, are supported by the Qolsys IQ Panel line.

Want a louder, more visible outdoor alert?

Smart Shield Systems will mount and enroll your PG9911/PG8911/PG4911, verify GOOD/STRONG RF, program tones and strobe timing, and test audibility—so neighbors notice and intruders don’t linger.
