Dimmer Selection
There are two types of dimmer switches, Push and Rotary. Our Dimmers are either 'rotary' meaning you turn the knob to switch on the lights and keep turning to brighten the lamps. Or 'push' where you simply push the knob to switch the lights on and then turn to the appropriate brightness. The advantage of the 'push' dimmer is that you can leave the lights at exactly the same brightness for the next time you want them on.

IMPORTANT
You must take into consideration the wattage of the lamps when selecting your dimmer. We sell 250w, 400w, and 1000w units. With all Halogen lamps you must downgrade the dimmer by half, here is a typical example: 10 x 50watt GU Halogen Lamps is 500watt therefore you require a 1000watt dimmer.


Single Pole & Double Pole
You will see that we sell Single Pole (SP) and Double Pole (DP) sockets and switches. The difference between the twois that single pole is commonly used for domestic purposes and double pole for commercial use, giving you complete isolation of the live and neutral.


2amp & 5amp Sockets
2amp and 5amp sockets would be used for lighting or low wattage items. You could wire them all to the main light switch, so when you enter your lounge the light switch would turn on the required number of table lamps/floor lamps around the room giving you an instant atmosphere around the room.


2 Way and Intermedite Switches
'2 Way' switches are used when two switches opertate one or more lights. 'Intermediate' switches are used when three switches operate one or more lights, large corridors etc.


Master & Slave Telephone Outlets
The first connection to be used in a system is a 'Master' and there after 'Slave' units can be used.

WHAT IS IP RATING? The resistance offered by the fixture to the penetration of solids and liquids is indicated by the IP (Ingress Protection) rating. This is a 2 digit number, the first number identifies the degree of protection against the ingress of solids and the second number against liquids e.g. IP65 indicates total protection against dust and protection against low jets of water. FIRST DIGIT PROTECTION AGAINST SOLIDS SECOND DIGIT PROTECTION AGAINST LIQUIDS 0 No Protection 0 No Protection 1 Protected against solid objects greater than 50mm (e.g. accidental contact with hand) 1 Protection against vertical water drops (e.g. condensation) 2 Protected against solid objects greater that 12mm (e.g. accidental contact with finger) 2 Protection against direct sprays of water, up to 15° from vertical 3 Protected against solid objects greater that 2.5mm (e.g. tools and wires) 3 Protection against direct sprays of water up to 60° from vertical 4 Protected against solid objects greater than 1mm (e.g. fine tools and wires) 4 Protections against water spray from all directions 5 Protected against dust 5 Protection against love pressure jets of water from all directions 6 Total protection against dust 6 Protection against jets of water of similar to heavy seas 7 Protection against immersion between 15 - 100cm 8 Protection against submersion

Bathroom Zones Explained.

Zone 1: Is the area directly above the bath or shower tray and to a height of 2.25m. A minimum rating of IP65 is required.

Zone 2: Is the area over the bathtub or shower tray above the sides of Zone 1 up to a distance of 60cm. This is external to Zone 1 and extends vertically 0.6M to a height of 3M. An IP rating of 64 is required.

Zone 3: Is the area external to Zones 0, 1 & 2, to a disatance of 2.4M from Zone 2 and a height above the floor of 3M. The protection required for luminaires in this zone foer normal domestic use is IP20.

Note: The above are guidelines only. Where water jets are being used for cleaning a minimum of IP65 applies.
