outdoor dual-tech curtain detectors
The alarm system is designed to protect the entire premises i.e. the building interior and the surrounding area. Security at the boundary between these two areas and along the fence of the plot is provided by curtain detectors, which belong to the group of perimeter protection devices.
Detector applications in
residential, business and industrial buildings:
- protection of building along its outer wall
- protection along the property fence
- protection of entrance gate or garage door
- outdoor and indoor protection of balcony / terrace / ordinary windows
- detection of entry into protected zone
- protection allowing for passage of pets

The compact and slim enclosures of the AGATE and AOCD-250 curtain detectors contain advanced technological solutions which enable a virtual wall to be created both outside of the protected buildings as well as in their interiors. The first of them is a wired device, so it can be part of any security alarm system. The other one is a wireless detector, designed to work as part of the ABAX two-way wireless system.
Enclosures of the detectors are made of a combination of polycarbonate and thermoplastic elastomer using two-component injection technology. The thus obtained design is IP54 rated, which makes the detectors suitable for outdoor applications as well.
The enclosure also contains elements which increase resistance of the device to mechanical impact. They include e.g. a special recess for the lens to protect it from being forced in, either accidentally or intentionally. Dual tamper protection against opening the enclosure and prying the device away from the wall is also applied. The protection is implemented using a contact on the electronics board and a tamper element on the back panel of the detector enclosure.
AGATE and AOCD-250 are provided with two detection circuits, infrared and microware, whose sensitivity can be independently and smoothly controlled. Thus, they can be adjusted both to the function performed by the device, as well as to the characteristics of the protected premises and its users' needs.
The detectors have a detection angle of 10° and an operating range of 14 m. At that distance, the emitted beam has a width of approx. 1 m.
Resistance to adverse weather conditions and temperature changes
The dual technology of detection combined with the detector algorithm of auto-tuning to environmental conditions provides high immunity of these devices to false alarms. Therefore, they offer stable operation in harsh weather conditions, such as rain, snow, fog, intense insolation and strong gusts of air. Additionally, the devices feature high mechanical strength and resistance to UV radiation, hence their appearance remains unchanged for many years.
The curtain detectors offer correct operation in a wide temperature range from -40°C to +55°C. Ambient temperature changes are automatically compensated.
For standard applications, we recommend installing the detector at a height of 2.4 m, with the lens facing down. This height may be different, however, if the device is to be used e.g. for protection of a window or gate.
The detector can be installed either directly on a flat surface or using a dedicated bracket that allows installation of the device at a constant angle of 90°. The second option is especially useful when securing a portion of the building wall with many windows. When installing the detector inside the building, you can also use other brackets offered by SATEL.
The detector can also be used to detect an entry into the protected zone which is not secured in any other way (e.g. separated by a wall, closed doors, etc.). Alternatively, the device can be installed low and, additionally, turned. Such a solution will provide protection and, at the same time, create a gap to allow, for example, a small dog to freely move around.
Design of the AGATE detector meets the EN 50131-2-4 standard requirements for Grade 3. Therefore, the device can be used to secure the premises particularly vulnerable to burglary, which require a high degree of protection, including the jewelry shops and interiors of public buildings.
According to EN 50131-2-4, active anti-masking function is implemented in the AGATE detector infrared circuit, which provides advanced protection against, for example:
With the active IR anti-masking function, all attempts to tamper with the device will be detected immediately, appropriate information being passed to the control panel. Depending on the system configuration, notification of the situation may be sent to the user, installer, security agency or a relevant department, e.g. police.
The AGATE detector lens is secured by a retro reflector of transparent polycarbonate. Any attempt to cover it with masking material will change the refraction angle of IR rays, which will be immediately detected and signaled by the detector.
AOCD-250 is a curtain detector designed to work as part of the ABAX two-way wireless system. It is supported by the ACU-120 and ACU-270 controllers, ARU-100 radio signal repeater and INTEGRA 128-WRL control panel. Owing to its efficient energy management, the detector can work up to 3 years without having to replace the battery. Importantly, the battery status is continuously monitored and, on detecting low voltage, the detector will sent appropriate information to the control panel.

AOCD-250 is an outdoor curtain motion detector which belongs to the group of perimeter protection devices. It is designed to work as part of the two-way wireless ABAX system. It is ideally suited for use both on the outside of the protected building, and in the interiors where difficult or specific environmental conditions prevail (in halls, shelters, sheds etc.). The AOCD-250 detector has two motion detection circuits ‒ PIR and MW. The dual technology, in conjunction with the algorithm of detector auto-tuning to the environmental conditions, provides high immunity to false alarms and hence stable operation in harsh weather conditions, such as rain, snow, sunshine and strong gusts of wind. The device offers correct performance in a wide range of temperatures from -40°C to +55°C, with the ambient temperature changes being automatically compensated.
The AOCD-250 curtain detector is characterized by a narrow detection angle of only 10 degrees and a range of 14 m. At that distance, the emitted beam (curtain) has a width of approx. 1 m. It is possible to install an accessory enclosure cover with the Fresnel lens AOCD-CL, which has an increased beam density and offers a maximum detection range of 10 m. Sensitivity of the detection circuits is configured remotely by using the DLOADX program. Because of the efficient energy management, the detector can operate for a long time ‒ up to three years ‒ without battery replacement.
What is also unique is the device enclosure, which is made using the two-component injection molding technology. The thus received splash-proof, IP54 rated design protects the AOCD-250 electronics against harmful atmospheric phenomena. In addition, the detector enclosure has high mechanical strength and is resistant to UV radiation.
Design of the AOCD-250 detector enables it to be mounted directly on a flat surface. The detector can also be mounted using a dedicated angle bracket (at fixed 90° inclination angle). When installing the detector inside the building, you can also use adjustable brackets such as BRACKET A oraz BRACKET B.
The AOCD-250 detector curtain meets the EN 50131 Grade 2 security requirements.
