IQ Dimmer-PG (3-Way)

The IQ Dimmer-PG (3-Way) is a PowerG-enabled smart dimmer designed to provide advanced lighting control and automation for compatible IQ alarm systems. It supports both single-pole and 3-way configurations, allowing users to control and adjust lighting from multiple locations while integrating dimming functionality into a connected smart home environment. The IQ Power Switch-PG (3-Way) is compatible with the IQ Panel 4, IQ Panel 5, IQ Pro, Qolsys IQ4 NS (no screen), and the IQ4 Hub PowerG versions.

In a 3-way configuration, the IQDMR3W-PG can be installed with either a standard 3-way switch or a second IQDMR3W-PG smart dimmer. When paired with a traditional 3-way switch, the smart dimmer provides full lighting control while the secondary switch acts as a basic on/off control point. For installations where full dimming control is desired from both locations, two IQDMR3W-PG dimmers can be used together, though both devices must be enrolled with the system.

If a standard dimmer is used in the circuit, it will not function as a dimmer and instead operates only as an on/off switch. For proper dimming performance across multiple control points, matching smart dimmers should be used. This flexibility allows installers to choose between cost savings or full multi-location dimming functionality depending on the application.

The IQDMR3W-PG communicates using PowerG wireless technology, offering long-range and encrypted communication with compatible panels such as the IQ Panel 4 and IQ Panel 5. This enables remote control through the system interface, mobile app, and automation rules. Lighting can be scheduled, triggered by system events, or adjusted to match different scenes throughout the home.

The dimmer supports smooth brightness adjustment, allowing users to fine-tune lighting levels for comfort and energy efficiency. It is designed for use with compatible dimmable lighting loads and should not be used with non-dimmable loads or smart bulbs. The device also includes a built-in air gap that allows power to be disconnected from the load for safe maintenance.

Installation requires a neutral wire and standard electrical wiring practices. The device is intended for indoor use and fits within standard electrical boxes. When properly installed, the IQDMR3W-PG provides flexible lighting control with the added benefit of automation and remote access.

The IQDMR3W-PG is a strong choice for users looking to add dimming capability and smart control to their lighting system, with flexible options for both simple and advanced 3-way installations. Alarm Grid also offers an IQSWH3W-PG, a non-dimming 3-way switch.
