Operates Lights at Night For a Timed Period
Product Ref: 1491£19.29 inc VAT
Part L of the Building regulations is changing and outdoor lighting needs to meet new standards namely...100w per fitting is the maximum permissible and these must be automatically controlled i.e. with a dusk to dawn sensor or used with a proximity or PIR detector.
This photoelectric switch with timer is a perfect automated solution to turn lights on at dusk and off after a preselected time period.
Programming is easy with a LED indicator lamp guiding you through both the Time On period and Lux level settings.
Light on is adjustable from 1 to 8 hours. Can also be set to operate from dusk till dawn if required.
Adjustable lux setting allows you to program at what light level you want your lights to come on.
Technical details: Switching level adjustable between approx: 5-300 lux 10Amp resistive load (2400 watts mains incandescent) 3Amp inductive load (720 watts loading for low voltage, discharge or fluorescent).
LED indicator light Construction ABS casing with gasket entry to the base for cable entry (1 or 2 flex up to 12mm in diameter) and has two 15mm diameter knock-outs to the rear if required.
Standards BS EN 60730-2-7IP Rating IP44 Colour Grey
Wiring Options - Has cable entry at base for two flexes with silicon gasket. There are two knockouts on the rear which can also be used (gaskets supplied).

Will this timer function correctly in a pigeon loft with no mains. In a scenario where lights are 12volts leds and power to unit is from 12 volt battery(s)
Are the fixing screws captive? As there are four of them it could be easy to loose some when adjusting the rotary switches.
Can this unit operate with an on/off switch for when no one is home.
I want to locate the sensor beneath the lighting source. Once the sensor is activated will it keep the lights on for the duration of the timer irrespective of the lux level from the nearby lighting?
Is there an override switch, i.e. if I set it to switch off after 2 hours and then decide I need to have lights on for another hour will I need to open the box to do that ?
Will this unit work in the USA on 110 volt input?
Can this or be connected up with SWA armoured cable?
Will this unit operate if mounted upside down? i noticed there is an up arrow on this, however the cables I hav would be entering from the topside so i would have it mounted upside down.
Is there room inside this for a single terminal block for earth wires if required?
I want to use this unit to switch four LED driveway lights, total combined load is about 8W, but have heard that some units don`t work with such low loads. Do you think that it will work okay in this application?
I need to have three outside lights switched via this unit. The bulbs that will be used are Phillips E27 ES 60watt each.
Will your unit be capable of doing this?
This seems to be he only automation device that can be used with a CFL bulbs (2 x 9W). Is there a PIR that will control them - or if I was feeling mad could I connect a PIR to turn on this dawn till dusk sensor which would then control the lights?
I have bought 2 similar units from Maplins in the past and they have both failed very quickly. I have a number of low energy fluerescent lights I am switching and was told this type of unit is not suitable.
I this really suitable for switching CFL bulbs
Having sensed dusk and switched on the load to which it is connected, does it then remain on for the programmed time, regardless of the light level rising again?
I currently have a MK masterseal light sensor which has failed after only 2 years. It has only 2 wires - a supply to it and an outgoing feed to the light. Will this unit replace my current one?
Can i have either a PIR or Sensors incorporated so as to operate several Non-maintained Emergency light fittings?
Is this unit suitable for low energy compact bulbs?
Prior to purchasing this product I need to know how the incoming power is connected as currently I have 2 double exterior sockets.
Is this unit suitable for low voltage garden lighting via a 250watt transformer
What is the input voltage?
Is this until fully weatherproof to be used outside?
