Product Description

The QOLSYS INC QR0074-840 is a 16-volt AC adapter designed to power IQ hardware used in fire detection and alarm panel installations. This accessory provides a dedicated power supply connection for compatible IQ Series fire panels, ensuring stable low-voltage power delivery to the control unit. Licensed alarm and low-voltage electricians typically source this adapter as a direct replacement or companion component during new installs or service calls where the original power supply has failed or is missing.

Installers working on fire alarm system upgrades or replacements will find this a necessary supply item when the panel requires a dedicated AC adapter separate from a battery backup circuit.
