GENERAL ELECTRICAL SPECIFICATION
                                 Version 2014-2



               2.10.5  Security Lighting


                         Two luminaires in the Restaurant and Kitchen areas are designated as security lights,
                         permanently ON. These shall be separately wired on the emergency lighting inverter
                         supply.
                         An interface shall be provided between the HVAC control panel and intruder alarm
                         system, when un-authorised entry to the building is detected all the store lights will be
                         switched ON. The lights will be switched OFF when the alarm is reset at the HVAC panel.

               2.10.6  External Lighting & Signage

                         Where the works to the electrical distribution require the temporary disconnection of the
                         external lighting circuitry, the existing circuitry and controls are to be  extended as
                         necessary and re–instated as originally installed.

               2.11  EMERGENCY LIGHTING

                         The Electrical Contractor shall supply and install a complete emergency lighting system to
                         satisfy the requirements of BS 5266-1.

                         It should be noted that all luminaires will be installed and tested by the Electrical
                         Contractor.

                         Luminaires shall be either: -

                         a.   integral with the general lighting luminaires by use of a converter pack(free issue)

                         or

                         b.  surface mounted self-contained units(supplied by LAUK)
                         or
                         c.   recessed independent luminaires with battery and inverter units (as supplied by
                              LAUK)

                         Emergency luminaires shall be wired on permanently live feeds directly from the main L.V.
                         distribution equipment. The restaurant lighting circuits shall be fed via one circuit in the
                         Schneider bus bar trunking system or LSF single core cables in conduit and trunking.

                         Emergency lights are to operate on mains failure, phase failure and local circuit failure.

                         The emergency lighting circuit shall be controlled via relays and contactors mounted on
                         the top of distribution boards controlled via the trend IQ3 controller panel. This control
                         arrangement provides the necessary final circuit monitoring and test facilities.

                         Contactors shall be as described for lighting control.
