I'm a bit confused about my expansion options using a Slave Expansion Module as there seems to be several different variants, and I want to make sure I get it right before ordering.My current system is a CM9000 with firmware 7.160. I have a UCM/ETH03 and a UCM/Pi. Also in the same box is an LEM03-M2 giving a total of 24 inputs and 8 outputs. I also have a spare LEM01-M2 with 8 inputs and 8 outputs. I only need additional inputs for the extra zones I am installing.
Some posts seem to imply that I cannot add an SEM with an LEM03 in the system, while elsewhere it says it can be installed in the last SEM only - which is correct?If the LEM03 can be used, then I propose moving it to the SEM and installing the spare LEM01 in the CM9000.In that case, can I use the SEM01C, as I won't need any more inputs and I would prefer to use the switch-mode PSU.
So, I think I need the SEP01C, which is the case + SEM + PSU. Sorry for being long-winded about this but I don't want to order the wrong parts.Thanks.

with older firmware LEN03 could only be added to the Controller, not to SEMs
With updated firmware for Comfort and Slave, the LEN03 ca be added to the last SEMNot sure what firmware it is but update to the latest

Thank you, I have ordered an SEP01C from Hunters, but it's on a three week lead time. I had hoped to get this project finished before I have to go back to work!:shock::D

Just a few observations about the SEP01C, which is the case + SEM01C + PSU I received recently.

Tamper switches are not supplied with the kit. Will the old style switches fit?
The case mounts flush onto the wall, with no stand-off for running cables behind it. There are knockout holes for cables.
The mounting holes on my LEM don't seem to line up the holes on the SEM01C. I can mount it below the SEM, but there are no threaded inserts for it. I can install standoffs in the holes below the SEM01C board, but they protroude from the back of the case and foul on the wall when it is mounted.

We have 2 enclosures, EN01D which is smaller 310 x 310 x 95 mm, and a larger one EN03D 358 x 375 x 94 mm. The EN03D sits off the wall, but EN01Damper witches isitys flush on the wall, with knock-out holes on the bottom and sides for cable entry. If you have not mounted it prhaps you can return and buy the larger box

The tamper switch is ordered separately ACC-TAMP as not all users want to install them. This is a plastic white tamper switch which clips into a round hole, not sure what type of swotch you used before

The larger box won't fit in my location, so I ordered some self-adhesive PCB stand-offs to mount the LEM.

Also, note that the internal PSU overlaps one of the top knock-out holes, so it needs to be removed before hitting the knock-out with a hammer. Otherwise you will break the mounting lugs on the PSU - ask me how I know :(

I also have the same problem..the LEM will not mount on top of the SEM with the stand offs...why the hell don't the holes line up...madness!!

Anybody got a link to the adhesive stand offs.....I have just purchased two SEMs and LEMs

Can you show a photo of the LEM on top of the sem to show how it does not fit? Weneed to check that the parts are correct

I have tried it all ways, cannot get the four holes to line up, the other one seems slightly different but is not to hand.

The LEM01 is not designed to sit and screw on top of the CM9001 PCB.  LEM02B with 8 input 0 outputs which is much smaller can sit and mount on top of CM9001.
There are too many pcbs eg OP03, ETH03, LEM02B  which have mounting positions on of of the PCB.

LEM01 is supposed to be mounted on the base of the enclosure where there ae screw posts provided for either UCM or LEM PCBs.

Hence either mount the LEM01B on the enclosure base, or get LEM02B if you would like to mount on top of CM9001
see the photo below for CM9001 with LEM02, ETH03, OP03 mounted (SEM02 is the same PCB as the CPU side of CM9001)

Hi,

My first problem is LEM02B is not listed for sale on the Laser website..that is really what I wanted to order. Have I been sold old stock? ( This means I now have an SEM with no EOL shunts and a LEM with shunts)

The second Problem is that to mount the LEM02-M2 in the bottom of the enclosure there are no mounting posts only holes..which means you have to have nuts protruding on the back on the enclosure which means it will not sit flush against the wall.

If you have LEM01-M2 with CM9001 the shunts should be positioned away from the terminal Blocks, ie require double EOL resistors, and you should install the 2 EOL resistors supplied (Your LEM01 in the photo has EOL shunts closer to the terminal blocks).  Please check with Laser regarding the parts you have been supplied as the website listing may be out of date.

LEM01-M2 and LEM02-M2 can be mounted o the base without protrusion. Next week I will show you a photo of the mounting method and correct standoffs to use

The LEM01 should be provided with the standoff as in the attached photo. As yoou see this is inserted from the bottom of the metal box and will not protrude from the bottom. There may have been a ix u in the standoffs supplied with the LEM01
