DSC PG9936 PowerG Wireless Photoelectric Smoke Detector

DSC PG9936 PowerG Wireless Photoelectric Smoke Detector

Overview

The DSC PG9936 is a wireless photoelectric smoke detector on the PowerG 915 MHz FHSS platform with 128-bit AES encryption. It delivers 85 dB of sounder output at 3 m and is UL 217/ULC S531 compliant. LED indicators show green for normal status and red during alarm conditions. The unit is designed for ceiling mounting.

Deployment scenarios

The PG9936 adds wireless smoke detection to DSC PowerG alarm systems, providing both local sounder notification and central station alarm reporting. It is deployed in residential bedrooms, hallways, and living areas as well as commercial spaces where hardwired smoke detector wiring is impractical or the building does not have a dedicated fire alarm system.

Detection and notification

Photoelectric sensing technology detects slow-smoldering fires with fewer false alarms from cooking or steam compared to ionization detectors. The built-in 85 dB sounder provides local audible notification. UL 217 and ULC S531 compliance ensures the detector meets North American fire detection standards.

Installation notes

Ceiling mount installation. Dimensions are 108 mm diameter x 48 mm (4.25 x 1.9 in). Operating temperature is 0 C to 38 C (32 F to 100 F). Powered by a single CR123A lithium battery with up to 5 years of life. PowerG wireless range up to 2 km open air. Front and rear tamper protection.

The PG9936 is the smoke detector I include in every PowerG system design. Photoelectric sensing is the preferred technology for residential applications due to its resistance to nuisance alarms from cooking, and the PowerG wireless protocol provides reliable communication with the panel.

Technical Highlights:

• Photoelectric sensing: Detects slow-smoldering fires with reduced false alarm rates compared to ionization technology
• UL 217/ULC S531 compliant: Meets North American residential fire detection standards for code-compliant installations

Deployment Considerations:

• Follow NFPA 72 placement guidelines for smoke detector spacing and location requirements
• The operating temperature maximum of 38 C means this detector is not suitable for attic installations or other high-temperature environments

Remember that the PG9936 reports to the alarm panel, not to a standalone fire alarm system. Ensure the monitoring station is programmed to dispatch fire services on the correct zone type.
