Guardian Introduces New Battery Backup GDO

Richardson, TX, June 23, 2020—Guardian Access & Door Hardware has introduced a new battery backup garage door opener.  The Model 728B, a ¾ HP equivalent 12V DC garage door opener, features a removable non-spillable battery power supply; motion activated and LED security lighting.  In the event of a power outage, the battery can supply power for about 20 cycles after 12-hr standby and provide about 300 use cycles.

Like every Guardian® operator, this new model is directly compatible with any version of HomeLink® and can be configured with a chain or belt, T-rail, C-rail or I-beam rail.

    The primary differences between the 715B and 728B, are the motors/pulling power and lighting.  The 715B is 1/2HP and 728B is 3/4HP equvalent in its pulling force.  The 728 will provide more light in the garage as it has two courtesy lights (200W) vs the single light (100W) on the 715B.

    The 728B is in stock in our Arlington, TX warehouse.  Neighborhood can order it.

    What features are different from the 715 vs 728b? I need a 3/4 Hp with battery back up- but neighborhood garage in dallas claims you don’t make this type of opener.
