Specification 40 Lighting and power control devices
S40C1
Scope
2019: Spec J6: 1
This Specification contains the requirements for lighting and power control devices including timers, time switches, motion detectors and daylight control devices.
S40C2
Lighting timers
2019: Spec J6: 2
A lighting timer must—
- be located within 2 m of every entry door to the space; and
- have an indicator light that is illuminated when the artificial lighting is off; and
- not control more than—
- an area of 100 m2 with a single push button timer; and
- 95% of the lights in spaces of area more than 25 m2; and
- be capable of maintaining the artificial lighting—
- for not less than 5 minutes; and
- for not more than 12 hours if the timer is reset.
S40C3
Time switch
2019: Spec J6: 3
- capable of switching on and off electric power at variable pre-programmed times and on variable pre-programmed days; and
- configured so that the lights are switched off at any time the space is designated to be unoccupied.
- a means of turning the lights on, either by—
- a manual switch, remote control or an occupant sensing device that on sensing a person’s presence, overrides the time switch for a period of up to 2 hours, after which if there is no further presence detected, the time switch must resume control; or
- an occupant sensing device that overrides the time switch upon a person’s entry and returns control to the time switch upon the person’s exiting, such as a security card reader or remote control; and
- a manual “off” switch.
- configured to limit the period the system is switched on to between 30 minutes before sunset and 30 minutes after sunrise is determined or detected including any pre-programmed period between these times; and
- capable of being overridden by a manual switch, remote control or a security access system for a period of up to 8 hours, after which the time switch must resume control.
S40C4
Motion detectors
2019: Spec J6: 4
- be capable of sensing movement such as by infra-red, ultrasonic or microwave detection or by a combination of these means; and
- be capable of detecting a person before they are 1 m into the space; and
- other than within a sole-occupancy unit of a Class 3 building, not control more than—
- an area of 100 m2; and
- 95% of the lights in spaces of area more than 25 m2; and
- be configured so that the lights are turned off when the space is unoccupied for more than 15 minutes; and
- be capable of being overridden by a manual switch only enabling the lights to be turned off.
- be capable of sensing movement such as by infra-red, ultrasonic or microwave detection or by a combination of these means; and
- be capable of detecting—
- a person before they have entered 1 m into the space; and
- movement of 500 mm within the useable part of the space; and
- not control more than—
- in other than a carpark, an area of 500 m2 with a single sensor or group of parallel sensors; and
- 75% of the lights in spaces using high intensity discharge; and
- be configured so that the lights are turned off when the space is unoccupied for more than 15 minutes; and
- be capable of being overridden by a manual switch that only enables the lights to be turned off.
- be capable of sensing movement such as by pressure, infra-red, ultrasonic or microwave detection or by a combination of these means; and
- be capable of detecting a person within a distance from the light equal to—
- twice the mounting height; or
- 80% of the ground area covered by the light’s beam; and
- not control more than five lights; and
- be operated in series with a photoelectric cell or astronomical time switch so that the light will not operate in daylight hours; and
- be configured so that the lights are turned off when the area is unoccupied for more than 15 minutes; and
- have a manual override switch which is reset after a maximum period of 4 hours.
- be capable of sensing movement such as by infra-red, ultrasonic or microwave detection or by a combination of these means; and
- be capable of detecting—
- movement of 500 mm within the useable part of the space; and
- a person before they have entered 1 m into the space; and
- be configured so that the lights dim to a 30% peak power or less when the space is unoccupied for more than 15 minutes.
S40C5
Daylight sensor and dynamic lighting control device
2019: Spec J6: 5
- for switching on and off—
- be capable of having the switching level set point adjusted between 50 and 1000 lux; and
- have—
- a delay of more than 2 minutes; and
- a differential of more than 100 lux for a sensor controlling high pressure discharge lighting, and 50 lux for a sensor controlling other than high pressure discharge lighting; and
- for dimmed or stepped switching, be capable of reducing the power consumed by the controlled lighting in proportion to the incident daylight on the working plane either—
- continuously down to a power consumption that is less than 50% of full power; or
- in no less than 4 steps down to a power consumption that is less than 50% of full power.
