Designed in Australia with the global engineering resources of Chamberlain, in partnership with Australian designers, Blue Sky Design Group, the Merlin MR850 roller door opener sets a new benchmark for garage door openers.  

User-friendly programming
The Merlin MR850 roller door opener is easy to setup and operation controls are easy to access, making it simple to add a maximum of sixty-four remote controls or to re-configure the roller door opener’s settings. A quick-connect socket for installation of a battery backup allows installers or users to effortlessly upgrade.  

Alarm output
Modern home security systems can monitor unauthorised intrusions if the Merlin MR850 roller door opener is activated.
