• Two out (Power) and two in (Trigger and Safety beams) terminals are provided to
support the connection of the most common external accessories
• The terminals can be accessed by removing the screw (Item 16) below the battery
housing (Item 15), and hinging down the Control Head cover.
Refer back to Section 3 - “Product Identification“
• The
SDO4 SMART
supports the Photon SMART infrared gate safety beams, which
are completely wireless safety ancillaries. Photon SMART beams can also be added
to another set of safety beams (wired or wireless) to add further functionality, safety
and peace of mind to the automated setup. The Photon SMART also delivers a much
neater and unobtrusive safety system as there is no need for unsightly mechanical
safety devices hanging from the ceiling of the garage
