The QOLSYS INC QC0004-840 is a 433 MHz radio daughter card designed to expand the wireless communication capabilities of compatible security and automation control panels. This add-on module installs internally within a host control panel, enabling the panel to receive and process signals from 433 MHz wireless sensors and peripheral devices. It is a single-unit accessory intended for installation by qualified security system technicians and integrators working with compatible QOLSYS control panel platforms.
This daughter card is suited for residential and light commercial security system installations where 433 MHz sensor compatibility is required. It is typically used during panel upgrades or system builds where legacy 433 MHz wireless devices need to be supported alongside or within a newer control panel environment. Installation is performed at the panel level, making it a low-profile, internal hardware addition rather than an external peripheral.
Designed as an OEM-style internal accessory for compatible QOLSYS control panels that support 433 MHz radio daughter card expansion.
Installation of this daughter card should be performed by a licensed or qualified security systems technician. Power down and fully de-energize the host control panel before handling any internal components or seating the daughter card. Follow the panel manufacturer's documentation for proper card orientation and seating procedures. Local codes and the manufacturer's installation guidelines govern this type of low-voltage security panel work.
