CD-2 and ACD-220


Invisible curtains guarding the windows and doors inside your home or business. Meet our curtain detectors in two versions: wired and wireless.

Slim, compact and effective. These are the CD-2 and ACD-220 indoor curtain detectors. Use them to cover doors, windows or other entrances to your building with an "invisible curtain". CD-2 is a wired detector, while ACD-220 is a wireless detector, operating within the ABAX 2 two-way wireless system.

Motion detection

The CD-2 and ACD-220 detectors are equipped with a passive infrared (PIR) sensor, which detects movement in the supervised area. Both detectors use a digital algorithm of motion detection and temperature compensation, which makes them exceptionally resistant to false alarms. Sensitivity of the CD-2 motion sensor is adjusted manually, using potentiometers located on the detector's electronics board. Sensitivity of the ACD-220 motion sensor can be adjusted remotely, making it very convenient.

Tamper protection

Both devices are equipped with tamper protection.
Any unauthorised attempt to open their enclosure or detach them from the ground will be immediately detected, triggering an alarm.

Easy and quick installation

The CD-2 and ACD-220 are easy to install. Their enclosure is opened with a special tool (included with the detectors), preventing any scratching. The detectors are supplied with specially selected components, which can be used to attach the detectors to almost any surface.

Power up

The CD-2 wired detector is powered by 12 V DC and is equipped with a voltage monitoring system. When the voltage drops below threshold, the detector will report a failure, informing the installer that servicing is required.

The ACD-220 detector is battery powered. Thanks to the energy saving mechanisms used, the service life of the device has been maximally extended, reaching up to 8 years (with the "ECO" mode activated). When the battery runs out, alarm control panel sends a warning.

Slim and elegant design

The CD-2 and ACD-220 detectors are designed to provide effective interior protection without negative impact on building décor.
Their small size makes them easy to install in window recesses or by doors. The detectors come in three available colours: white, brown, and dark grey, making it easy to match them to your interior. The appearance and size of the enclosures match the design of other detectors offered by SATEL: universal - wired (XD-2) and wireless (AXD-200), as well as the AGD-200 wireless glass-break detector. Unified appearance of system devices creates a feeling of order and design.

Automation system support

Both detectors can be work within home automation systems. Whenever they sense movement in the detection area, the system can take specific action, like switching on lights, and more.

A perfect match for any building

Each building is different and requires an individual approach to the alarm system design.

Due to various building characteristics, sometimes a better option is to choose a wired installation, while somewhere else running cables might not be entirely possible. That's why our indoor curtain detectors are available in two variants to provide uncompromising protection wherever an 'invisible curtain' is needed. Choose the best version for your alarm system.
