          How do the PDL 600 and 800 series product codes work?

          As a general rule of thumb -
          PDL items require PDL at the front of the code.
          600 series item codes start with 6.
          600 series switch codes start with 68.
          The number of switches fitted in the plate is the 3rd number in the code, 681 = single 600 series switch, 682 = double 600 series switch
          600 series socket codes start with 69.
          The 3rd digit in a socket code indicates the type of socket, 691 = single vertical socket, 692 = double vertical socket, 694 = single horizontal socket, 695 = double horizontal socket.
          Most codes require a colour code at the end, WH = white, BK = black.
          eg. To order a black double vertical switched socket the complete code would be PDL692BK.
          800 series (Modena) item codes start with 8 and follow the same format as above. (800 series items with Strato plates start with S8...)
          eg. An 800 series Modena double switch in white = PDL882WH, a Strato double horizontal switched socket in black = PDLS895BK 
          In both series metal cover plates are an extra option to be supplied separately, coded to fit the plate required, eg. 600 series single switch metal plate in Stainless Steel = PDL681MSS (M = Metal, BBZ = Brushed Bronze, PB = Polished Brass) Some plastic cover plates are available eg. PDL681CWH (C = Cover), PDL800PSCH (PS = Plastic Surround, CH = Champagne, there are 9 colour options in 800 series)
          Strato brushed aluminium plates also need BK or WH to decide the trim colour, eg. PDLS800CBABK or PDLS800CBAWH (C = Cover , BA = Brushed Aluminium)
          Module grids with covers are available in BK or WH, eg. PDL684VHWH (VH = vertical/horizontal since the grid is empty and module can be fitted either way), PDLS800GPSBK (GPS = Grid, Plate, & Surround).
          Grids without covers included are only available in Modena 800 series, PDL800G (horizontal) or PDL800GV (vertical)
          Refer for further details and options.

          Is the PDL681VH available in red?

          no, it is only available in white or black

          Is the 692C available in black?

          No - PDL692CWH only
          or the metal plate options:
          PDL692MSS - Stainless Steel
          PDL692MBBZ - Brushed Bronze
          PDL692MPB - Polished Brass

          What is the PDL plate to suit the 100MPIR sensor mechanism?

          The PDL681VH will suit the 100MPIR.

          Does the PDL56CV320 have round pins or flat pins

          PDL56CV320 has round pins

          Is the modena vertical single switch the same size as a 600 Series single switch.

          The size for a modena Single Switch PDL881V - 85mm (W) x 124mm (H) x 9mm (D) - Mounting Centres - 84mm

          PDL681WH - Plate size 118mm(h) x 74mm(w) - Mounting centres 84mm

          What is the replacement isolator for an oven

          The replacement is a PDL 680
          we have a range of 32amp switch and 45anmp switch which should suit

          PDL380M32 , PDL680M32wh 32amp
          PDL647wh 45amp

          Will a PDL 56P420 fit into a PDL56SO520

          Yes it does

          What plate is required to fit the on/off and auto/manual switches with a 100MPIR?

          The installation sheet for the 100MPIR is at

          Please note, the code for the on/off switch is now 681M16HFS, if you want a switch with a hinged flap printed SENSOR, which is good to avoid the switch being turned off accidentally. Also please be aware of the load limitations on the PIR, it is not rated for use with LED's.

          With the 2 switches and the PIR as seen in the instructions you will need a triple plate, as long as these are the only switches you want on the plate, which is a PDL683VH. This is the grid and cover plate, available in white or black, and if you need a metal cover plate you will also need to order the PDL683M** where the ** is either PB for polished brass, BBZ for brushed bronze, or SS for stainless steel.

          There is another option if you find the triple plate too busy or you have other switches to go in the plate, there is a 3 position rotary selector switch available that does Auto Off Manual in one switch, so with the PIR you will only need 2 module holes (PDL682VH). The rotary switch code is 687M3A/M which you can see at:
