EL-55 Wired Dual-element Infrared Detector for Home and Business Security

This wired infrared alarm from the EL-55 series offers a straightforward approach to motion detection. Designed to be wall-mounted, it uses a dual-element body inductor to sense infrared heat from people moving within its range. Suitable for houses, supermarkets, schools, and banks, it provides practical coverage where a reliable alert is needed. The detector connects via a wired link to a compatible alarm system, ensuring continuous operation without battery changes. With a detection angle of 120 degrees and a range of 6 to 10 metres, it can monitor a broad area from a single fixed point.

Features and Construction

The EL-55 is built around a dual-element sensor that responds to human body heat, reducing the chance of false triggers from small animals or environmental changes. Its wired design means a steady power supply from the alarm panel, and the wall-mounted form factor makes installation straightforward in corridors, entrances, or main rooms.

Dual-element Sensor

The dual-element design compares two sensing elements to detect moving body heat, which helps distinguish human presence from background temperature fluctuations. This provides more accurate detection for security purposes in busy environments like shops or schools.

Wired Power and Signal

Operating on a 9-16VDC supply, the detector integrates directly with most standard wired alarm systems. The wired connection eliminates the need for battery replacements and ensures a constant link to the control panel, making it a low-maintenance option for professional or home use.

120-degree Coverage

With a detection angle of 120 degrees, this unit can cover a wide field of view when mounted on a wall. Paired with a detection distance of 6 to 10 metres, it suits rooms up to mid-size while maintaining sensitivity to movement across the monitored area.

Uses and Placement

The EL-55 is designed for indoor use in a variety of settings. Its wall-mounted installation and wired connection make it a practical choice for locations where a permanent security solution is required, from family homes to public buildings.

Home Security

In a domestic setting, the detector can be placed in hallways, living rooms, or garages to alert residents to unexpected movement. The 120-degree coverage helps cover doorways and windows from a single unit, and the wired connection integrates with existing home alarm panels.

Commercial and Institutional Use

For supermarkets, schools, and banks, the detector provides reliable motion detection in corridors or storage areas. The dual-element sensor reduces false alerts in busy environments, and the wide detection angle minimises blind spots. Operating temperature range of 10 to 60 degrees Celsius ensures it works in most indoor conditions.

Professional Installation

Because it is wired, the EL-55 is best installed by a professional or someone familiar with alarm systems. The low static current of 15uA means minimal power draw, which is a benefit for systems with many detectors. The unit is supplied as a single piece with necessary hardware for wall mounting.

Benefits and Buying Value

Choosing a wired dual-element detector like the EL-55 brings stability and a long service life without battery worries. Its focus on accurate body heat detection provides genuine security value in both residential and commercial settings.

Low Power Draw

The 15uA static current keeps power consumption very low when the detector is idle. This is especially useful in large alarm systems where multiple detectors are connected, helping to keep overall energy use down without sacrificing coverage.

Reliable Wired Connection

With a wired communication method, there is no risk of signal interference or battery failure. This makes the EL-55 a trustworthy component in a security network, offering constant monitoring and quick response to any detected movement within its range.

Versatile Application Range

Whether protecting a family home or a busy institution, the detector’s 120-degree angle and 6-10m distance cover a useful area. The dual-element sensor adds a layer of reliability, and the wall-mounted design keeps it discreet while maintaining a clear field of view.
