The BLAZE-PRO PE Cell is a plug-and-play photoelectric daylight sensor thatturns any BLAZE-PRO floodlight into a dusk-to-dawn fitting. IP65,with four selectable lux thresholds set by remote.

What it does, and why the sensor adaptor interface matters

• It switches the floodlight on as daylight falls and off as it rises notimer to reset twice a year, no contactor, no separate control wiring.
• Every BLAZE-PRO carries a sensor adaptor interface, which is what makes thisplug-and-play rather than an electricians job. It fits the range, not onemodel.
• Which is the practical argument for the BLAZE-PRO range generally: you can specifythe plain fitting now and add dusk-to-dawn control later without replacing anything.
• Four lux thresholds 10, 20, 50 or 100lux, selected by remote.The default is 20lux.

It needs a battery that does not come with it

The remote that sets the lux level requires a CR2025 coin cell, and it is notincluded.

• Without it the sensor works but cannot be adjusted it runs on its20lux default and stays there.
• 20lux is a reasonable default and many installations would never change it.But if you want the light coming on earlier (100lux) or holding off until properly dark(10lux), you need the battery on site.
• This is on the datasheet and in no product field. Buy a CR2025 withit it costs very little and it is a wasted trip otherwise.

Choosing the lux threshold

The threshold is also the run-hours dial. On a fitting rated to 20,000 hours,choosing 10lux over 100lux measurably extends the replacement interval and reducescomplaints from neighbours about a floodlight coming on in the afternoon.

Specifying it

• IP65 one step below the IP66 floodlight it mounts on. Stilla genuine outdoor rating, but the sensor is now the weakest point of the assembly. Worth knowing on awash-down or fully exposed site.
• Operating range 30C to 40C; installation height 8mfor the floodlight.
• Remote control distance 08m you must be able to get within8m of the fitting to change the setting, which on a high mounting means a ladder or a longreach.
• Adjustment: loosen the M4 set screw with a 2mm Allen key toaim it. Have the key on site it is not the size most people carry.
• The datasheet also quotes an installation height of 1.84m, a 120 field and asensitivity distance of 28m. Those are motion-sensor figures rather thanphotoelectric-cell ones, and they sit alongside the dusk-to-dawn description on the same document.If you need motion detection rather than daylight switching, ask us which accessory you actuallywant Domus makes more than one.

Two record entries that are not true of a sensor

• Built-in LED as the bulb type. It is a control accessory nothing in it lights up. The eighth product in this catalogue carrying a lamp type on hardware with nolamp.
• Indoor as the application, on an IP65 outdoor daylight sensor. Thatfield holds Indoor on 340 of 342 Domus records.

Where it works

• Yards, car parks and driveways that should light at dusk without anyoneswitching.
• Sites where a timer keeps drifting a photoelectric cell tracks the realseasons, a timer does not.
• Retrofit onto an installed BLAZE-PRO, using the sensor adaptor interface.
• Not where motion switching is what you actually want this is daylightswitching; it will stay on all night.
• Not on a mounting you cannot get within 8m of if you intend to change thesetting.

Specifying it

Plug-and-play photoelectric daylight sensor for the Domus BLAZE-PRO floodlight range. Dusk-to-dawnswitching. Lux thresholds 10 / 20 / 50 / 100lux, selected by remote; default 20lux. IP65.Operating range 30C to 40C. Remote control distance 08m. Aim adjustment via anM4 set screw, 2mm Allen key. Fits BLAZE-PRO models via their sensor adaptor interface. Requires a CR2025 battery for the remote not included; without it the sensor runs on its20lux default and cannot be changed. Our record lists a bulb type and an indoor application; it isan outdoor control accessory. Warranty not recorded.

Questions

Do I need a battery?

Yes a CR2025 coin cell for the remote, and it is not included. Buy one with the sensor. Without it the sensor still works, but it runs on its 20 lux factory default and you cannot change the threshold, because the remote is the only way to set it. This is on the datasheet and in no product field, and it is a wasted trip if you find out on site.

Which lux setting should I choose?

The default 20 lux suits most installations it brings the light on at normal dusk. Choose 50 or 100 lux if the site is overshadowed or you want light before you need it, and 10 lux if you want to minimise run hours and light spill onto neighbours. It is worth treating as the run-hours dial: on a fitting rated to 20,000 hours, 10 lux against 100 lux measurably extends the replacement interval.

Will it fit the floodlight I already have?

If it is a BLAZE-PRO, yes. Every model in the range carries a sensor adaptor interface, which is what makes this plug-and-play rather than an electrician’s job and it is a good argument for the range generally, because you can specify the plain fitting now and add dusk-to-dawn control later without replacing anything. Tell us the model and we will confirm.

Does it detect movement?

It should not it is a photoelectric cell, which switches on daylight level rather than motion, so the light comes on at dusk and stays on until dawn. Worth flagging, though: this accessory’s datasheet also quotes a 120 field and a 28m sensitivity distance, which are motion-sensor figures sitting alongside the dusk-to-dawn description on the same page. If motion switching is what you actually want, ask us which accessory you need Domus makes more than one.

Does it lower the IP rating of the assembly?

Slightly, and it is worth knowing. The sensor is IP65 where the BLAZE-PRO floodlights are IP66, so once fitted the sensor is the weakest point of the assembly. IP65 is still a genuine outdoor rating and fine for rain and general exposure. On a wash-down site or a fully exposed coastal position, that one step matters.

How do I aim it?

Loosen the M4 set screw with a 2mm Allen key and adjust. Have the key on site 2mm is not the size most people carry in a van, and it is the difference between finishing the job and coming back. Note also that the remote only works within 8m of the fitting, so on a high mounting you need to be able to get close enough to set the lux level.

Is it better than a timer?

For dusk-to-dawn, yes, and for one specific reason: a photoelectric cell tracks the actual seasons and a timer does not. A timer set in summer has the light coming on an hour late by mid-winter, and someone has to remember to reset it twice a year. The cell simply reads the light level. Where a timer still wins is when you want the light off at a fixed hour rather than at dawn this will run all night.
