Napco PHW8RETRO 8 Zone Hardwire Takeover Module

Product Description

The NAPCO SECURITY TECHNOLOGIES PHW8RETRO is an 8-zone hardwire takeover module designed to integrate existing hardwired security sensor loops into compatible NAPCO control panels. The module allows installers to retain legacy wired detection devices during a panel upgrade, eliminating the need to replace in-wall wiring or end-of-line resistor networks. It falls within the miscellaneous power accessories category and is sold individually. Licensed alarm installers and low-voltage security technicians are the primary users of this device in both residential and light commercial retrofit applications.

The PHW8RETRO is suited for retrofit and upgrade projects where a building already has hardwired door contacts, window contacts, motion detectors, or glass-break sensors wired back to a central location. Rather than pulling new wire or converting to wireless sensors, the technician connects existing zone wiring to this module to preserve the original detection infrastructure. It is particularly useful in occupied spaces where wall disruption must be minimized during a security panel modernization project.

Key Features

• Supports up to 8 hardwired security zones for panel integration
• Enables takeover of existing hardwired sensor loops during control panel upgrades
• Sold as a single unit, suitable for one panel position or zone expansion slot
• Reduces retrofit labor by preserving in-place wiring infrastructure
• Designed for low-voltage security system applications

Compatibility

Designed as an OEM-style hardwire takeover module for use with compatible NAPCO SECURITY TECHNOLOGIES control panels in residential and light commercial security system installations.

Installation Notes

Installation should be performed by a licensed low-voltage or alarm systems technician in accordance with local codes and NAPCO panel documentation. Power down the control panel and disconnect the backup battery before handling or connecting the module. Verify zone wiring continuity and end-of-line resistor values before terminating leads to the module. Consult the panel manufacturer wiring guide for correct terminal assignments prior to commissioning.
