4.4 Product description
The low-power-system (LPS) "NETLIGHT quattro" is a decentral safety lighting system for the supply and monitoring of max. 80 escape sign or emergency luminaires on a total of 4
circuits with NETLIGHT MSÜ technology in the circuit types continuous light, ready light and switched continuous light.
The emergency luminaires are operated exclusively with 230 V AC alternating current! The supply voltage in emergency operation is obtained from a maintenance-free, sealed battery
system. The integrated battery management system continuously monitors the charge status and functional reliability and controls charging. Emergency operation is triggered by an
internal network monitor, which monitors the supply network in single-phase or three-phase mode.
All operating events can be displayed in detailed and comprehensible text in a desired programmable language on the user-friendly control panel with four-line plain text display. The
navigation keypad can be used to navigate through the menu. For text input, a standard PC keyboard can be connected via the system's USB port.
The test logbook of the security lighting system is stored in the system memory and can be loaded onto a USB stick (with single-level cell technology) at any time via the USB
interface or, if the device is connected to an existing LAN home network on site, directly into the desired PC directory. The LAN home network (browser) can also be used for remote
control; the complete control panel of the device is then displayed on the PC and can be operated as if it were operated directly on the device. All screens of the master display are
also displayed on the PC screen in real time. On the other screens the status states, measured values from the AC home mains and the battery, as well as incoming messages can be
displayed.
The Netlight quattro has three signalling contacts (fault, battery operation and system ready for operation) which can be used to call up the device status and output it to a panel, for
example.
The battery system is located in the device housing or additionally in the expansion housing (option). The battery connection cable can be found in the device.
The four final circuits have a selective short-circuit cut-off system. The total device power can be freely allocated to the circuits, depending on the max. output power of 200VA per
circuit.
4x control inputs (inputs 1-4) for 230V AC switching voltage and 4x control inputs (inputs 5-8) for potential-free contacts are available, which are optionally programmable for
switching operation, local emergency operation, continuous or standby light switching, blockage or manual acknowledgement.
Interconnecting two control inputs and the device connection for 230V AC allows for three-phase mains monitoring.
Furthermore, a control input (input 9) is available which provides loop monitoring via a 1Kohm resistor.
Control panel with 4-line plain text display, 7x signal LEDs for indication status also easily readable from a distance, 4x timers for time-controlled automatic functions,
TCP/IP interface for Ethernet networking, max. up to 255 devices, max. length up to 100m, integrated WEB server for remote control/remote display.
With the optional external module bus option, up to 15x external three-phase network monitors (BUS-capable) can be connected to the system.
