9/1/2023 0 Comments Illuminations led![]() In Maintained devices, pressing the button for 2 seconds will allow you to dim the Maintained light flow, from maximum brightness to minimum 10% intensity. By simply by pressing the button you can, at any moment, verify the device functionality or by pressing and holding the button for 5 seconds you can perform the autonomy test. Many HARPER devices are equipped with a button which provides the installer with numerous functions. They can be powered by a voltage between 160 and 260Vac and can be used as ordinary luminaires or be connected to a centralized supervision system. Central-Battery The devices are not equipped with batteries but have a circuit with an electronic driver for the activation of the LEDs. BUS Disconnected), the devices continue to function in a completely autonomous way and perform both the functionality and autonomy tests using the same procedure and times as the Self-Test. In all cases communication failure with the control panel (e.g. Bus-Supervised The devices are equipped with an interface which is electrically isolated from the rest of the electronic circuitry, this permits communication via BUS and therefore can be continuously monitored by a control panel. In this way the installer can carry out regular maintenance in a precise and almost effortless way due to the fact that the lamp itself signals any faults that may be present. The device performs a FUNCTIONALITY TEST which runs every 14 days and a battery AUTONOMY TEST which runs every 28 days. Require connection to the 230Vac mains network only.Self-Test The emergency lighting devices are equipped with a microprocessor which manages the device (On/Off), its functions and its battery life. Standard Self-powered devices, complete with battery. Non Maintained - The luminaire switches On only when there is a power cut on the mains power line. This is normally required for evacuation routes. Maintained - The luminaire remains On continuously both when the mains power supply is present and when it is not. The various levels of autonomy, different protection grades which satisfy the requirements of all environments and accessory-device flexibility determine suitability for all applications. The Harper series offers a vast selection of LED lights for all emergency lighting needs. The durability and performance of Harper emergency luminaires is further enhanced by new LiFePO4 long-life batteries which are smaller and more environment-friendly than standard nickel-cadmium or nickel-metal hydride batteries. The light source of the HARPER emergency luminaires series is an optimal blend of new generation long-life LEDs rated to over 50 thousand hours, high light output, low energy consumption and, thanks to an exclusive patented optical lighting design, highly effective glare-free technology that complies with all regulations regarding photobiological safety. In critical situations emergency luminaires provide crucial illumination and for occupants who must find their way out of a building. ![]() ![]() The lights can go out when least expected, for instance during extreme weather conditions, a fire hazard, work in progress or even network overload.
