Wireless Expander Module :

 The system shall have the facility to use expander modules to boost the signal strength and coverage of the translator modules where required.

  Each expander module shall be capable of communicating in a direct routing path.

 Each expander module shall be capable of communicating with a minimum of 32 Field Devices.

  Expander modules shall require a separate power supply unit capable of working on voltages between 10 - 27V dc.

 Expander modules should be programmable without the need of special tools.

 Expander modules should be provided with license free software to for support programming

  The expander module shall include : for improved system coverage.

  The translator shall include : Radio transceiver using a license free 865 MHz CPR approval to EN54 part 18 and 25 Annex-B Technical Specification of FDA system Radio transceiver using a license free 865 MHz CPR approval to EN54 part 18 and 25 Approx. quantity – 08 nos. for both Guest Houses. Exact nos. may vary. Vendor requested to visit site & be present at pre tender meeting before submitting tender.One no. Wireless Kit for commissioning / testing : Test & diagnostic equipments : The system will have PC based diagnostic and commissioning tools for use when commissioning or testing the system

  These tools shall include :

The system shall include a portable site survey tool which will determine signal strength of field devices prior to installation. Special Condition of contracts – Technical Before quoting Bidders are requested to visit site.

System Components :

  The fire system shall be analogue addressable and devices are to be installed throughout the areas nominated as part of the system design. The system shall consist of analogue addressable fire detection, wireless smoke and heat detectors, manual call points, sounders and visual alarm indicators which use an 865 MHz frequency network to communicate with the control and indicating equipment (CIE).

  All wireless devices shall be powered by an internal power source consisting of easily replaceable lithium batteries of standard manufacture. The power source shall give the device an operational life of at least three years in normal conditions (EN54 part 25). Each power source shall be monitored and capable of reporting is condition to the CIE. When the battery capacity is low, a low battery condition shall be indicated at the CIE allowing 30 days of normal use for the battery pack to be replaced.

  All wireless devices shall be capable of operating over a minimum of seven (7) operating channels.

Annex-B Technical Specification of FDA system :

  All wireless and wired analogue addressable devices shall be of the same visual appearance.

  All wireless devices shall be powered by standard off the shelf lithium batteries. No special battery packs or non-standard cells will be used.

  All wireless devices shall have two independent lithium battery supplies. A primary cell to power the device under normal conditions and a secondary cell to maintain the operation of the device should the primary fail.

  In normal working conditions field device battery life should be :
-   Detectors, Call Points and Input Modules : Primary Cell - 5 Years , Secondary Cell - 2 Months,
   - Warning and Output Devices : Primary Cell - 3 Years
