Sensor technology and signal processing:
The individual sensors can be configured manually or timer-based via the LSN network. All sensor signals are analyzed continually by the internal evaluation electronics (Intelligent Signal Processing – ISP) and are linked with each other via an inbuilt microprocessor. The link between the sensors means that the combined detectors can also be used where light smoke, steam or dust must be expected during the course of normal operation.
Optical sensor (smoke sensor):
The optical sensor uses the scattered-light method. An LED transmits light to the measuring chamber, where it is absorbed by the labyrinth structure. In the event of a fire, smoke enters the measuring chamber and the smoke particles scatter the light from the LED. The amount of light hitting the photo diode is converted into a proportional electrical signal. The DO detectors use two optical sensors with different wavelength. The Dual Ray Technology works with an infrared and a blue LED, so that light smoke can be detected reliably (TF1 and TF9 detection).
Thermal sensor (temperature sensor):
A thermistor in a resistance network is used as a thermal sensor, from which an analog-digital converter measures the temperature-dependent voltage at regular intervals. Depending on the specified detector class, the temperature sensor triggers the alarm status when the maximum temperature of 54 °C or 69 °C is exceeded (thermal maximum), or if the temperature rises by a defined amount within a specified time (thermal differential).
Improved LSN features:
The 420 Series Fire Detectors offer all the features of the improved LSN technology:
Further performance characteristics:
The detector alarm indication takes the form of a red flashing LED that is easily visible 360°. It is possible to activate a remote external detector alarm display. The detector base no longer has to be directed due to the centralized position of the individual display. The integrated strain relief for interfloor cables prevents the removal of cables from the terminal after installation. The terminals for cable cross-sections up to 2.5 mm2 are very easily accessible. The detector bases have a mechanical removal lock (can be activated/deactivated). The detectors have a dust-repellent labyrinth and cap construction.

With the aid of special mounting kits, the housings can be mounted in 482.6 mm (19") cabinets. All housings can be extended with various additional housings for all conceivable applications.
Operation / processing of messages:
The operation and the processing of all messages are easy and intuitive thanks to the ergonomically- designed control panel with its TFT touch‐screen offering a menu-driven handling and multi-color display. To that end, there are permanently located keys on the right, bottom, and upper edge of the display as well as variably located virtual keys in the touch-screen area.
Modular Structure of the FPA‐5000 Modular Fire Panel:
Due to its modular structure, the FPA‐5000 Modular Fire Panel provides complete flexibility and thus customized solutions for any application.
The functional modules are autonomous, encapsulated units that can be inserted into any control panel slot using "plug-and-play" technology. Thus, the power supply and the data traffic to the control panel are indicated automatically without any additional settings. The module is automatically identified by the control panel and functions in the default operating.
Wiring to external components is performed using compact connector/screw terminals. After a replacement, only the connectors need to be reinserted; extensive rewiring is no longer required. defined as network node or local node. Within a group, only panel conditions of the same group can be displayed. Regardless of the groups, network nodes allow for the display and handling of all panel conditions. Local nodes display the conditions of the related panel.
The Address Cards activate detection points. The FPA‐5000 governs up to 4096 detection points. Each element and input which, after the programming, is able to set off an alarm requires a detection point. Inputs are considered as detection points if they are programmed accordingly in the FSP‐5000‐RPS Programming Software.
