The Sentry RDO Max is a 24V roll-up garage door motor for domestic and light industrial use. It fits most domestic roll-up doors with plastic or metal spool wheels and turns one spool wheel to roll the door up or down. The motorised head unit fits inside the door curtain roll, and the wall console holds the power supply, 2 backup batteries, the remote receiver, an LED courtesy light and a control button.

Will it fit your door?
The RDO Max is made for the standard roll-up doors found on most homes, made from thin laminated steel or aluminium. Sentry does not recommend it for the much heavier steel roll-up doors from the 1970s. One motor drives one door, and on a very wide door it is fitted in the centre with an extra adapter wheel. Door height makes no difference, so standard and caravan-height doors both work.
The door has to be in good condition before a motor goes on. It should roll up and down easily by hand, without tight spots. Bent or warped spool wheels must be replaced or fitted with an adapter wheel, and a very light door may need a length of angle iron added along the bottom edge.
Battery backup for power cuts
Two 12V batteries sit inside the wall console, and the RDO Max keeps them charged. When the power goes off, Sentry rates the backup at up to 10 cycles, depending on the condition of the batteries. The wall console warns you with beeps and its status LED when the mains is off or the battery is low. When the batteries get old, the RDO Max takes 2 x 12V 1.3Ah or 1.4Ah batteries, such as our 12V 1.4Ah sealed lead acid battery.
Safety
Collision sensing stops and reverses the door if it hits something, and you can adjust how sensitive it is. Sentry strongly recommends safety beams, and auto-close only works with beams fitted. With beams in place, the door can close on its own after 20, 40, 60, 80 or 100 seconds. Add Sentry wired safety beams or Sentry wireless safety beams.
Remotes and extra devices
The 2 remotes in the box come programmed on the blue button. The built-in code-hopping receiver stores up to 100 remote buttons, so you can add Sentry 1 button code-hopping remotes for the rest of the household. The trigger input also takes an external receiver, a GSM or WiFi module or a wall button, and the wall console supplies 24V DC to power it.

No. One RDO Max drives one door, and two motor head units can't be fitted to one door. On a very wide door the motor is fitted in the centre with an extra adapter wheel.
Use the manual release lanyard to disengage the motor, then move the door by hand. To engage the motor again, pull the release cord until the motor head locks, as shown in the manual.
