Dusk til dawn switch - Photoelectric with timer

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 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)

Run back timer adjustable to stay on between 1-8 hours after switching.

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.

Is this until fully weatherproof to be used outside? This unit is IP44 rated which means that it offers protection from entry by tools, wires, etc., with a diameter of thickness greater than 1.0mm and also protection from splashed water. In short it is suitable for general outdoor use.

What is the input voltage? 230 volt mains i.e standard incoming mains.

Is this unit suitable for low energy compact bulbs? Yes it will switch CFL and any other inductive to loads to maximum of 720w.

Can i have either a PIR or Sensors incorporated so as to operate several Non-maintained Emergency light fittings? A non-maintained emergency light comes on when the power supply is interrupted. They should be connect to a live mains supply at all times. If you have maintained emergency light they have two supplies: one as above; and one switched supply. You can use a PIR or dusk til dawn photocell on the switched supply. If you need more clarification please call us

Is this unit suitable for low voltage garden lighting via a 250watt transformer This unit is suitable for low voltage lighting up to a maximum of 720watt, so yes.

Prior to purchasing this product I need to know how the incoming power is connected as currently I have 2 double exterior sockets. The easiest solution would be to take power via your exterior socket via a flex. Wire this into the switch and connect the outgoing (switched live) to your lighting. Then you can allow the photoelectric switch to switch on and off your lights automatically or manually switch them off via your switched double socket. For safety your external socket should be the type that closes securely with plug in place.

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? We have not undertaken any tests to replicate this scenario. However if this higher light level is maintained for two minutes the unit will switch off.

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? The MK dusk til dawn sensor is just a photoelectic sensor. This is a more complicated product and as such requires a neutral feed as well as a live supply.

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 We have sold this unit for around four years and have not received any feedback about issues with CFL loads. Assuming you are not using cheap CFL lamps ie Philips Genie or anything from Poundland we cannot foresee any problem.
