Fire detection system operation
This document provides an overview and instructions for operating an automatic fire detection system at a hotel. It describes the key components of the system, including the Bosch FPA-5000 modular fire panel, intelligent addressable detectors, manual call points, and notification appliances. It explains how to install and connect the different detectors, operate the fire panel interface for bypassing zones, viewing history logs, and conducting drills and resets. The document also outlines the working principles of optical and thermal detectors and shows how to install and operate the manual call points.

- 1. What is FireDetection System? An automatic fire alarm system is designed to detect the unwanted presence of fire by monitoring environmental changes associated with combustion. In general, a fire alarm system is classified as either automatically actuated, manually actuated, or both. Automatic fire alarm systems are intended to notify the building occupants to evacuate in the event of a fire or other emergency, report the event to an off- premises location in order to summon emergency services, and to prepare the structure and associated systems to control the spread of fire and smoke.

- 13. Optical & Thermaldetector operations Working principle:- Optical: light scattering principle: If the wavelength of light is less than the particle size, light gets scattered by that particle. All optical detectors will have an LED and a photodiode. When the smoke particles enter the smoke chamber, the light from LED gets scattered by the smoke particles and falls on photodiode generating a current .All Bosch LSN improved detectors has an intelligent signal processor to process the electrical signal and compare it with about 5000 stored values, to decide whether to give alarm or not. Thermal: 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).

- 16. Manual call point(MCP) operation The FMC-210-DM Manual Call Points are used for manual triggering, and are deployed in the Local Security Network LSN and LSN improved. Form H Manual Call Points are designed for outdoor deployment, form G Manual Call Points are designed for indoor deployment. 1)In the event of an alarm, the glass pane 2) is broken first, then the manual call point 3) is pressed hard. This activates the micro switch for alarm triggering and the indicator LED 4) blinks. A mechanism holds the pressed call point down. The manual call point can be reset with the reset lever 5)By closing the door of the manual call point (1). The indicator LED (4) goes out. *Identification with display of the call point address on the fire panel ensures the quick location of the triggered call point.
