The QOLSYS INC QC0005-840 is a 345 MHz SRF (Sub-Radio Frequency) radio daughter card designed for integration into compatible security control panels. This internal expansion card adds or restores 345 MHz wireless sensor communication capability to a host panel, allowing the panel to receive signals from 345 MHz enrolled devices. Installation is performed by a licensed security systems technician during panel setup or field service. It ships as a single unit and mounts directly onto the host control panel board.
This daughter card is suited for residential and light commercial security installations where 345 MHz wireless sensors are deployed. It is used when a control panel requires a dedicated radio module to support that frequency band. The card is added during initial system build or as a replacement when the existing radio module has failed or needs to be upgraded to restore sensor communication on the 345 MHz band.
Designed as an OEM-style replacement or expansion radio daughter card for compatible QOLSYS INC security control panels that support 345 MHz SRF wireless communication modules.
Installation should be performed by a qualified security systems technician familiar with low-voltage electronic work. Power down and disconnect all power sources from the host control panel before handling or seating the daughter card. Handle the card by its edges to avoid electrostatic discharge damage to onboard components. Follow all applicable local codes and the host panel manufacturer guidelines during installation.
