If the standard test instruments are not available then firm must produce certificate of any Govt. accredited lab or National Accreditation Board for Testing and Calibration Laboratories (NABL) approved laboratory or International Laboratory Accreditation Corporation (ILAC) approved laboratory. vii) Weight Less than 15 Kg BOO will check practically to measure weight by weighing machine. viii) Power source i) DC -13.8 Volt + 15% ii) AC – 230 Volt + 15%, 50Hz iii) There should be provision to shift automatically on DC supply during mains failure & when mains Apply 230 VAC ±15% and 13.8 VDC ±15% one by one and check that whether set is working properly or otherwise. 155 supply restored it should be shifted on mains from DC supply ix) Protection (i) Reverse polarity protection (ii) Protection against high VSWR i) BOO will check it by connecting Radio set with DC supply in reverse polarity and switch the set to“ON’ position. There should not be any harm to the Radio Set. ii) BOO set be switched “ON’ removing antenna/dummy load and PTT be pressed. In such a condition there should not be any harm to Radio set. 2 Transmitter i) RF Power output 45 Watt or more (programmable / Selectable) B.O.O. will check all these parameters in the entire frequency range mentioned in the QRwith the help of standard testing instruments. If the standard test instruments are not available then firm must produce certificate of any Govt. accredited lab or National Accreditation Board for Testing and Calibration Laboratories [NABL] approved laboratory or International Laboratory Accreditation Corporation (ILAC) approved laboratory. ii) FM Hum & Noise -40 dB or better iii) Modulation Limiting + 2.5 KHz @ 12.5 KHz iv) Adjacent Channel Power -60 dB or better v) Audio Distortion Less than 3% 3 Receiver i) Sensitivity i) Analog :- 0.30 μV (12 dB SINAD ) or better ii) Digital :- 0.30 μV at 5% BER or better B.O.O. will check all these parameters in the entire frequency range mentioned in the QRwith the help of standard testing instruments. If the standard test instruments are not available then firm must produce certificate of any Govt. accredited lab or National Accreditation Board for Testing and Calibration Laboratories [NABL] approved laboratory or International Laboratory Accreditation Corporation (ILAC) approved laboratory. ii) Selectivity (Adjacent Chanel ) 60 dB or better iii) Inter-modulation 70 dB or better iv) Audio Response +1,-3 dB v) Rated Audio Distortion Less than 3% 4 ENVIRONMENTAL SPECIFICATION i) Operating Temperature -300C to +600C Firm must produce certificate of any Government accredited Lab. or NABL or ILAC ii) Storage approved laboratory. Temperature -400C to +700C iii) Humidity Max. 95% @ +400C non-condensing. 5 Networking Should be capable to support IP site connects. Firm will show Networking and interfaces related function of repeater practically by connecting it in user organization network. 6 Interfaces Ethernet port RJ-45 to provide a) Wide area IP connectivity for Voice and Data. b) Remote monitoring and status check. 7 Accessories Battery cable & Mounting fixtures Should be supplied with Repeater B.O.O. will check it practically by connecting battery cable & mounting fixtures with repeater. Antenna i) 3dB/6dB gain Omni directional antenna BOO will check it practically by connecting with 45 meter RF Cable RG-217 for base station will beprovided as per quantity mentioned in list of store. transmission there should be no mismatch between radio and antenna. Programming kit All necessary programming software and hardware required for the set will be provided as per quantity mentioned in list of store. BOO will check it practically that all necessary programming software and hardware are available as per user requirement. Literature i) User’s manual with each radio sets should be provided free ofcost in soft as well as hard copy. ii) Technical repairing manual with complete block diagram, circuit layout etc should be provided in soft as well as hard copy as per quantity mentioned in list of store. BOO will check it physically that user and technical manual are available as per user requirement. 8 Field Trial The actual performance of the radio set will be assessed. Field trial of equipment will be conducted by a Board of Officers in the operational area of the force in the presence of Vendor/representative of firms to ascertain the user satisfaction beforethe proposal is accepted. Radio equipment withall required accessories will be provided by the participating firm’s on “No Cost No Commitment” basis at the indenter discretion
