How to set up Ajax control of roller blinds or roller shutters. Connection diagrams

Why are roller blinds and roller shutters needed, and what types are there

Roller blinds and roller shutters differ in purpose. Roller shutters perform protective functions and block access to the territory or premises. And roller blinds are used similarly to curtains — they protect from light and prying eyes.

Roller shutters can be used to protect windows, doors, and glass roofs. Roller shutter gates and grilles are also worth mentioning.

Decorative roller blinds are usually installed indoors. Their curtains can be insulated to reduce heat loss. They protect from sunlight and, to some extent, provide sound insulation.

Types of roller blinds and roller shutters by the control method

Roller blinds and roller shutters are opened/closed manually (mechanically) and/or by electric drive. Mechanical roller shutters can be automated using an electric drive.

Which roller blinds/roller shutters can be controlled with Ajax

Ajax can control any roller blinds/roller shutters equipped with an electric drive.

If the roller blinds/roller shutters are equipped with a controller (more expensive and rare models), you will need to connect wiring to its control terminals. In the absence of a controller, make a connection directly to the electric drive.

Connection to the drive

The Ajax system allows you to control roller blinds and roller shutters with an electric drive of any kind — with 110/230 V AC mains (most models) and low-current type (12/24 V DC).

Power electric drives, as a rule, are installed in protective roller shutters, and low-current ones are more often found in decorative roller blinds.

Information about the type of electric drive can be found in the equipment manual and/or on the roller blinds/roller shutters manufacturer’s website.

Connection to the controller

Some roller blinds/roller shutters models can be equipped with a control unit. It consists of a controller and control devices such as remote controls. The controller receives commands from control devices and activates the open-close mechanism.

To integrate with Ajax, the controller should have a control input for connecting wired buttons and relays. The controller can have a non-standard control input or special control and operation modes, which also should be taken into account during integration.

Before starting to connect the equipment, study the technical documentation for roller blinds/roller shutters.

What devices are used when connecting

Main devices:

• Roller blinds or roller shutters with an electric drive.
• Hub — coordinates the operation of system devices.
• Relay low-current relay — gives the command to open or close roller blinds/roller shutters with a low-current drive or controller.
• WallSwitch power relay — controls the power supply for the equipment and gives the command to open or close roller blinds/roller shutters with a power drive.

With the help of WallSwitch, roller blinds or roller shutters can be de-energized upon command from the application or automatically when arming. This way, intruders will not be able to open the roller blinds or roller shutters, even if they have gained access to Button.

Additional devices:

• Transmitter Jeweller integration module — transmits to the system in real-time the status of roller blinds/roller shutters: open or closed.
• Transmitter Fibra integration module — detects the break-in or the status of roller blinds/roller shutters: open or closed.
• Button — allows sending a command for roller blinds/roller shutters opening or closing.
• Ajax opening detectors — detect break-in of roller blinds. Available for DoorProtect S Plus Jeweller, DoorProtect Plus Jeweller, DoorProtect Plus Fibra, and DoorProtect G3 Fibra.
• Back-up batteries of appropriate capacity and output current — for opening or closing the curtain in case of power loss, as well as for back-up power supply of Relay and/or WallSwitch.

The hub can run up to 16 hours on a back-up battery, and the rest of the Ajax devices run 2 to 7 years on pre-installed batteries.

Security requirements

Connect roller blinds and roller shutters according to manufacturer’s instructions, observing the general electrical safety rules.

Do not disassemble energized devices. Do not use devices with a damaged power cord.

Do not connect Relay to a power supply with a voltage higher than 36 V or AC circuits. Also, do not connect WallSwitch to a voltage that goes beyond 184–253 V (230 V networks) and 88–121 V (110 V networks). This is a fire hazard and will damage the device.

Avoid getting moisture on Relay or WallSwitch or cable connections.

Considering the operating temperature range and the operating humidity of the Ajax relay — devices should not be placed outdoors.

We recommend using roller shutters equipped with an emergency manual lifting system — in case of a prolonged power outage or fire.

How to connect roller blinds/roller shutters to Ajax to control opening-closing

The connection diagram and the type of relay depend on the type of roller blinds/roller shutters control system:

• Opening and closing is initiated by a 110/230 V power supply — WallSwitch is used.
• Opening and closing is initiated by a 12/24 V supply — Relay is used.
• Opening and closing are controlled by the controller — Relay is used.
