we've traveled down to guilford today we're at signify and it's an absolutely glorious day so
don't feel sorry for us but we'll be down here for well we're here to follow up on a product we've
seen on the channel before gary we've previously reviewed the philips lighting solutions for
upper air and surface disinfection and as we all know we've been living through challenging times
but now we're thinking about returning to work and employers want to make their spaces as safe
as possible for their employees so we're going to see how powercore have installed those products
within the signify officers and how they enable the solutions going so we're going to start this
uvc journey by looking at surface disinfection and the most common application area for that is
the toilet now we're looking for kyle from power cor and rumor has it he's loitering in this toilet
kyle are you in here yes ah there he is well filming locations don't get more glamorous than
this and he's the person responsible for this installation it's kyle from Powercor so Kyle
what have you installed in this rather glamorous toilet so we have installed some
uvc batten fittings above the sink areas over here as well as smaller batten fittings in each cubicle
addition to that we've got the sensors that get triggered in each cubicle and the main toilet and
front door we've got dual contacts on each door before entering and additionally we've got the
emergency stops in case of an emergency and somebody's locked in the bathroom okay so
obviously a lot of that's because exposed uvc light isn't uh doesn't mix well with people
um so it's a lot about the safety of the users and you've wired that back to a control system we have
yes which is just outside well let's go and have a look at that and see how it all works together
so Karl brought me here the control system you've installed just briefly talk through how the system
works all right first and foremost we need to make sure that the area is clear of any people okay
so that's yeah how do you do that though you put sensors in there we have indeed there's a sensor
in each area as well as each cubicle okay because the pir sensors as well aren't they yes yeah and
obviously we've all seen that the cad operator in the office who doesn't move enough and the light
switches off above his head there is a risk that somebody in there could yeah possibly be asleep
and it would be possible to activate the system so that's why that human check's there he's there
okay so you've cleared the area what happens then once air is clear we'll come out to harm
the system when that happens it'll check to make sure that every area is clear before
we set it there's then a countdown timer before the system is engaged and if everything's clear
the system will engage okay and how long does that run for that can run from 15 minutes up to an hour
so the system's now running for 15 minutes but what happens you know you've armed the system
then walked off and i tried to walk in there to obviously use the toilet so another safety
procedure we have in place is door contacts on every door so as soon as that dual contact is
broken the system disengages okay and you've also added a further i guess if all these
safety measures didn't perform there is still an emergency stop button in there as well there is
there's one in each bathroom and if somebody did get caught in there they can hit that emergency
stop okay so i mean this you said is it is a pre-built control system it is it comes all ready
to go okay sort of out of the box well let's have a look in the box just to see how easy that was to
wire keep the efixx viewers happy if we don't see some wiring for a while get a little bit nervous
so this is built around a standard dynalite control system it is what's going on in the panel
here so we have power coming in and then that gets routed through a contactor which brings the lights
on the bathrooms we have the emergency stops coming back which are wired in the door contact
and all the sensors that's a pretty neat panel i say it's all configured now we know one of the
issues with uv is obviously over time the lamps degrade how do you know at what point you need to
possibly look at replacing the lamps so built into the system we have a screen which counts
up every time they've been used and that will indicate when we need to change the lamps i can
just demonstrate that okay so it's yeah it's good yeah it comes it warns you that it's getting close
to close replacement and then lab replacement uh required so all in all this looks like a pretty
good system that deals with the safety aspects of what could be a challenging system it does yes
well let's go and find gary i think he's with matt somewhere looking at the upper air
disinfection system that we've also installed in his offices this is becoming a sort of
a major business opportunity for power corps it is yes we've seen a steady incline in the enquiries
into uvc we've already installed them in rugby clubs schools and some public transport offices
so i've tracked back down and using the plant room i've got one thing to address first matt
yeah this is kyle's high visibility jacket and it looks absolutely immaculate however yours matthew
looks like it's been used by somebody doing work what have you been up to on this project uh okay
so we work nights um just to ensure the safety of everyone so there's no one in the building
and there's a team of myself and two of my colleagues um we have followed the design whereby
the opera units are split into six zones and we've wired it in fp200 right and behind you've
got the control panel i can see all the lights are illuminated should we have a look in there
yeah sure let's have a look so the six zones are illuminated then map so i take it that the
wall and ceiling mount uvc lamps are currently on yeah correct so if i want to look in here i've got
pressing emojis to stop is that right yep i've already done it so we're in trouble already so
open up our panel oh this looks like it was purpose-built unlike the one gordon saw that was
actually shipped in is that correct yeah that's correct so parkour purpose built this unit as
opposed to the one outside the bathroom unit and it houses all the control systems so you've got
network power supply the dynolite relay control system and then up top you have the essentially
the outgoing circuits for all the different zones so this is the fp200 going out feeding
the wall and ceiling mounted ones we've also got the optex red scan which i think those lasers are
wall mounted and is it when one of those is broke that actually knocks off the system yeah correct
actually just above we've got the optics red scan poe switches so power over ethernet that sounds
rather technical should we pass that one back over to the old clean coats yeah probably best too
so kyle we're out here in the main office area so what we've actually installed on the uvc side
out here so we've got some upper air wall mounted uvc units and we have also got the optex red scan
sensors okay so we learned in our last video that we made about these products there's a lower risk
when it comes to these upper air disinfection unit the main risk is if someone was to say
climb on a desk hanging some christmas decorations up or something like that and they're staring into
the unit so how does the red scan device help with that safety precaution so yes you're correct
there's always an opportunity where somebody could stand on a desk or a contractor could come in
climb up some steps and be exposed to the uv light we've installed some optex red scan
sensors which basically cast a beam across just below the fittings as soon as that beam is broken
it'll turn the units off in the zone okay so if i was to jump from here into the path of the uv
light it should cut off correct oh well that's that that's a pretty sensitive device so is that
a laser beam sort of that does that it is yes so it casts a beam 20 square meters which we've
cropped to fit the installation of this building and when you break that beam anything greater
than 10 millimeters it'll cut the power off to the units via control panel wow that's i mean
that's a great solution so you develop that just obviously for this first install yes yeah in terms
of placement of the uv units how's that decided how many you need and how far apart they should be
so an initial survey was undertaken by signifier they will determine the space and the requirements
for what volume needs to be sanitized by the uvc units and it all comes into heights of ceilings uh
space obstacles they'll calculate that and they'll give us a plan okay and then it was yeah we've
seen that kyle did all the work installing it and yeah we come along for the bit to celebrate the
results as people come back to work what a great environment we've got here to come back to work
what we got installed here in this breakout zone so we've got the upper air disinfectant uvc lights
okay and they give a 360 degree output against the ceiling correct yeah and you've installed
these in here and also in the cafeteria area as well but i noticed there's also a lot of
things hanging from the ceiling you've got some pendants and yeah phillips are always
changing the range did you have to make a count of those when you start looking at those sensors
we do so within that laser range we've got to account for anything that's hanging in the area
make sure that we've got the whole area covered and we may need to mask out a few areas
additionally if anything does change in that space we need to be able to
come back and recommission those lights to make sure that they are in the right location ethics
viewers know i'm big on my training and my cpds we're all qualified electricians was there any
additional courses carl that we had to take in order to install this yes there was we needed
to undertake the signify training course for uvc which included understanding the product
installation and commissioning apart from that the electrical system is identical to
any other we would be fitting is that right yes it is so with that in mind we'd like to
thank powercall for showing us around today and i'm going to grab gordon and see what it's up to
so what do you think you've learned from my trip down here to signify well it's been fantastic to
see those products were featured on the channel a few months ago put into practice and what people
mustn't forget is that uvc is not a new technology for disinfection you know you could put it in
the air conditioning system and a lot of people are starting to talk about that now but what we
believe is the air conditioning system has to work incredibly hard for that to be effective
there may be some regulation changes coming up that means you have to have more air changes in
an environment in a space and UV-C can help you get around that but remember also getting to
those surfaces as we saw in the toilet you can't do that from the air conditioning now and i think
power core demonstrated there clearly this is an opportunity to electrical contracts and they've
done a fantastic job here haven't they they have understood the requirements of the client and
then gone off and searched out the best solution for the safety requirements of the system and a
cracking install that hasn't disrupted the work here so i bet people are really looking forward
to getting back in and driving it forward as always we're interested in your comments
and your feedback please leave those all below and we'll try and get back to as many as we can
