Powered with wired connectivity or wireless freedom

The OJ Waterline™ WLM3 Master is a universal controller that can be used for both wired and wireless communications depending on your design needs.

Wired communication

The OJ Waterline™ WLM3 Control System gives you the power to install masters that ensure proper area control through standard 2-core cables wired to low-voltage sensors (only 5 volts) and controllers which guarantee end-user safety. Wired connections can be up to 300 meters with up to 100 meters between any two units.

Wireless communication

Wireless connection to room controllers/sensors can be established with the same masters by simply connecting a receiver. Wireless offers very high flexibility when either retrofitting current systems or if you need to add additional zones to an existing installation.
