e remote shutdown panels the illumination levels should be sufficient for control panel operators.186 (2) Suitable sealed-beam battery-powered portable hand lights should be provided for emergency use by the fire brigade and other operations personnel required to achieve safe plant shutdown. (3) Fixed emergency communications independent of the normal plant communication system should be installed at preselected stations. (4) A portable radio communications system should be provided for use by the fire brigade and other operations personnel required to achieve safe plant shutdown. This system should not interfere with the communications capabilities of the plant security force. Fixed repeaters installed to permit use of portable radio communication units should be protected from exposure fire damage. Preoperational and periodic testing should demonstrate that the frequencies used for portable radio communication will not affect the actuation of protective relays. 6. Fire Detection and Suppression a. Fire Detection (1) Detection systems should be provided for all areas that contain or present a fire exposure to safety-related equipment. 9.5.1-47 DRAFT Rev. 4 - April 1996 (2) Fire detection systems should comply with the requirements of Class A systems as defined in NFPA 72D (Reference 24) , "Standard for the Installation, Maintenance, 187 188 and Use of Proprietary Protective Signaling Systems," and Class I circuits as defined in 189 NFPA 70, "National Electrical Code.".190 (3) Fire detectors should be selected and installed in accordance with NFPA 72E , 191 "Automatic Fire Detectors.". Preoperational and periodic testing of pulsed line-type 192 heat detectors should demonstrate that the frequencies used will not affect the actuation of protective relays in other plant systems. (4) Fire detection systems should give audible and visual alarm and annunciation in the control room. Where zoned detection systems are used in a given fire area, local means should be
