1. centralized power supply centralized control fire emergency sign lamp (hereinafter referred to as sign lamp) is composed of shell, shell cover, tempered glass plate, driving communication module, LED light source, etc.
2. The sign lamps are in the form of normally open lamps, i.e. normal lighting, emergency lighting, and lamps are displayed. When the normal power supply is lost, it will automatically switch to the emergency state, which will be powered by the external emergency power supply, and the emergency time of power failure shall not be less than 90 minutes; The lamp is single-sided indication, and the installation methods include suspender type, ceiling type, wall type, etc; The signs include: "emergency exit", "left", "right", "two-way" and other words or patterns for users to choose. Grounding screws are set inside and outside the sign lamp, which can be reliably grounded when users use it.
3. The shell of sign lamp is cast aluminum alloy ZL102. The product shell adopts one-time die casting process, with smooth surface, beautiful and generous appearance, high density of metal internal organization, no bubbles, sand holes and other defects, strong impact resistance and good protection performance of the product shell.
4. After the surface of the sign lamp is treated by a series of processes such as high-speed shot blasting, the advanced automatic high-voltage electrostatic plastic spraying and thermosetting integrated assembly line process is adopted. The plastic layer formed on the shell surface has strong adhesion and is not easy to fall off, which effectively achieves the purpose of protecting the shell and improves the anti-corrosion ability of the product.
5. There is no storage battery inside the sign lamp, which is powered by the centralized power supply of emergency lighting
6. Super bright green LED light source is adopted, and the service life of the light source is 100000h
7. The light source of the sign lamp is subject to uniform light treatment through the light guide plate to make the surface of the sign lamp emit light evenly, and the surface brightness meets the requirements of the national standard of 50 ~ 300cd /
8. LWhen the sign lamp is in abnormal state, it can automatically start the fault alarm.
9. It has non continuous, continuous, stroboscopic, direction adjustment, forced lighting and other working modes, and has the functions of patrol inspection, light on, light off and so on
10. A microcomputer chip is set inside the lamp, and each lamp has an independent address code, which can remotely upgrade the software in the lamp
11. High protection structural sealing design, the sealing gasket is formed by continuous line pouring and foaming of two-component polyurethane sealant strip, and the protection grade reaches IP67.
12. All exposed fasteners are made of stainless steel.
13. Steel pipe or cable wiring can be used.
