Series Wireless Smoke and Heat Detector

Why Choose This with Smart Shield Systems

• Code-aware placement: we install detectors outside sleeping areas and on every level, following NFPA 72/UL guidance for spacing and environmental limits.

• Clean integration: we enroll the device to your PowerG panel, verify supervision (≈128-sec heartbeat), and document alarm/restore, tamper, and trouble reporting.

• Fewer false alarms: we avoid high-humidity/drafty spots and use the Silence (hush) feature correctly—about 7 minutes for smoke alarms; 12 hours for low-battery chirps.

Key Features

• Photoelectric smoke + fixed 135 °F (58 °C) & rate-of-rise heat detection in one device.

• Built-in 85 dB sounder with ANSI Temporal-3 pattern and bright alarm LED.

• Two-way PowerG wireless with encrypted communications and automatic supervision.

• Test/Silence button: quick functional test; smoke hush ≈7 min, low-battery hush 12 hr.

• Visible link-quality indicator for faster, confidence-checked placement.

• Long transmission range for many repeater-free installs; typical 3-year battery life.

Compatibility Notes

• Works with PowerG-capable DSC panels (e.g., PowerSeries Neo, iotega) and other compatible receivers; also widely used with Qolsys IQ panels that support PowerG.

• On alarm, the detector sounds locally and signals the control panel, which can trigger other sirens/alerts per programming (this is not a hardwired interconnect).

Popular Use Cases

• Hallways outside bedrooms & each level of the home (primary life-safety coverage)

• Basements, utility areas, living spaces—with heat backup for fast-rising temperature events

Frequently Asked Questions

Where should these be installed?

Place detectors outside each sleeping area and on every level, avoiding areas with drafts, high humidity, or extreme temperatures. Follow NFPA 72/UL and the manual’s diagrams for spacing. We handle this for you.

How do I test or hush the alarm?

Press and hold Test/Silence to sound the unit and signal the panel; for a nuisance alarm, press to silence for ~7 minutes. Low-battery chirps can be hushed for 12 hours.

What powers the detector and how long will it last?

It uses three AAA batteries (specified brands) with ~3-year typical life; the detector reports low battery to the panel and chirps locally.

What events does it report to the panel?

Alarm/restore (smoke or heat), tamper/restore, low battery, and trouble/maintenance; the device also sends a supervisory signal about every 128 seconds.

What heat features are included?

In addition to smoke sensing, the unit includes fixed-temperature 135 °F (58 °C) and rate-of-rise heat detection for quicker response in fast-heating fires.

Ready for monitored, code-compliant fire protection?

Smart Shield Systems will place, enroll, and test your PG9936/PG8936/PG4936 detectors, set up professional monitoring and mobile alerts, and schedule maintenance reminders—so your home gets fast, reliable warnings when it matters most.
