Dsc PGP9979 Wireless Heat Detector 915 Mhz

Product Description

The DSC PGP9979 is a PowerG wireless heat detector operating at 915 MHz, designed for integration into DSC PowerG security and life-safety systems. It monitors ambient temperature conditions and triggers an alarm when heat levels exceed a fixed threshold, providing early warning of fire conditions without requiring a wired connection to the panel. The 915 MHz frequency delivers long-range, two-way encrypted communication with a compatible PowerG receiver. Installation is handled by licensed security and fire alarm technicians working in residential and light commercial applications.

The PGP9979 is suited for locations where smoke detectors are not recommended but heat detection is required, such as kitchens, garages, attics, and utility spaces. It functions as part of a wireless zone within a DSC PowerG alarm panel installation. The device is sold individually and is typically deployed where wiring a conventional heat detector is impractical or cost-prohibitive.

Key Features

• 915 MHz PowerG wireless communication for extended range and reliable signal penetration
• Two-way encrypted wireless protocol for tamper-resistant communication
• Fixed-temperature heat detection suitable for environments where smoke detectors are not appropriate
• Wire-free installation reduces labor time in retrofit and new construction projects
• Designed for use in residential and light commercial life-safety applications

Compatibility

Designed as an OEM-style wireless heat detector for use with DSC PowerG-compatible alarm panels and receivers operating at 915 MHz.

Installation Notes

Installation should be performed by a licensed security or fire alarm technician in accordance with local fire and building codes, including applicable NFPA standards. Power down or disarm the alarm system before adding or replacing wireless devices on the panel. Follow the panel manufacturer's enrollment procedure to register the device to a wireless zone. Do not install in environments that exceed the detector's rated temperature or humidity range as specified in the product data sheet.
