    2.0 GENERAL REQUIREMENTS

    2.1 Automatic Fire Detection & Alarm System (AFDAS) shall consist of the following: 2.1.1 Fire Detection & Alarm System (FDAS) - comprising of any

    or all of the following detection systems:- (a) Bimetallic Heat detectors for Diesel Generator/Oil

    Storage room. (b) Heat and Smoke multi sensors for Power Supply Room. (c) Linear Heat Sensing (LHS) cable along with its interface

    module (for cable trays, cable troughs & cable bunch etc.)

    (d) Aspirating (air sampling) type smoke detector for Relay Room.

    2.1.2 Alarm & Control Unit (ACU) - For reading the signals from sensors/detectors, giving audio/visual alarms.

    2.1.3 Other Items (OI) - like connecting cables, relays etc. necessary for commissioning & reliable operation of the AFDAS.

    2.2 The AFDAS shall be designed to work on power supply of 24 V DC ± 20% and also on 230 V AC± 20%. It shall have in-built charging facility to have 24V battery backup (VRLA as per IRS: S-93/96(A) or latest) for at least 24 hours. It shall power the Linear Heat Sensing Cables and all detectors, Manual Call Points etc., which constitute AFDAS.

    2.3 The AFDAS shall be self-checking & diagnostic type. It shall continuously monitor the health of the sensors/ detectors & the complete system including battery. The data regarding health & event shall be logged in the system with date & time stamp, which can be downloaded to a PC/ Laptop at later stage. The system should have capacity to store data for up to a minimum of 3000 fire events. The Alarm Control Unit (ACU) shall be networkable to the Zonal/Divisional Railway headquarters preferably over TCP/IP.

    2.4 The system shall be suitable for installation in electrical cabinets, transformers, invertors, cable trays, electronic equipments, power equipment rooms, relay rooms, or any other enclosed areas, which are vulnerable for fire as deemed fit by Indian Railways.

    2.5 The system shall be suitable to detect fire/ fire like situation in relay room, power equipment room, electronic equipment, electrical wiring etc., and generate audio/visual alarms.

    2.6 The AFDAS
