if all the equipment u mentioned located at the same place... the this models will fine for u = SF9812DSL, SF9512DSL... if u look for more socket or support higher current = SF9512DSL MS2+3, IT pack...

but make sure ur installation dont have any back kick for lightning, otherwise ur PC set wont safe even used the most expensive lightning protection...

that is the "back kick"... he using SP9201DSL only which protect tel line but not the power line... the surge come from power line thru the power adapter and strucked the modem, but surge not coming from tel line... and i mentioned to J-Slade bear the risk himself if he insist want to protect the tel line only, although i recommended for correct models... even though used the belkin brand which protect the tel line only, the result with be the same...

power adapter sometimes wont burnt as well even got the surge, if may able to overcome fluctuation of the electric but modem not able to overcome it... some equipments are sensitive on electric, some are not... if those sensitive 1 they may not able to handle more than 0.1A electric as well... that why SL-AR (1.5A) was designed for low power comsumption and senstive equipment... lets say we plug a equipment which only 0.5A, and used SC0039 which can support up to 10A... cal-lab wont work efficiently if the lightning surge was 1.5A but cal-lab support 10A equipment. the extra 1A will enough the burn the sensitive equipment.... somemore the fuse in the extension socket can support up to 13A and ur PC must be 5A at least... i strongly advised that use correct models for correct equipments... not free lunch in this world...

such as this PSU spec, it can support up to 7A...


furthermore, all the equipment sure have the lifespan, wear and tear will occur... so pls dont think tat after used cal-lab and our equipments will alive forever...

sometimes we can heard tat lan port is fried by lightning but modem still working fine... i had a real case from my fren... which means the his modem able to "tolerate" with surge but not the lan port... that why i keep saying the installation is the most critical...

if i told cal-lab staffs about J-Slade equipment installation and the models he using, sure they will say definitely unsafe... so far i used cal-lab 1year++, only 1 units cal-lab burnt by lightning when i online during heavy rain but my pc safe... the sig below was my "obsoleted" rig spec and they still alive since 12/2004, not hardware replacement before...

u can purchase RM10 insurance for ur PC equipments, but T&C as well...
the insurance will valid for the correct installation... u can get RM5k from insurance company if ur equipment confirmed damaged by lightning only and cal-lab failed to protect...

in fact, the insurance company wont do non profit business, if insurance company know the cal-lab not effective on lightning protection, sure they wont affiliate with cal-lab which may caused them pay plenty times for RM5k...

but if u confirmed without any back kick, without insurance is fine...
isolation method had patented by USA, which means it is effective enough to protect equipment so the USA permitted this copyright only owned by cal lab owner, so far i hvnt hear the belkin get any patent from any country...

if u using 1 set of pc and 1 unit modem/router, plus dont have other equipments connecting to ur PC/modem/router which will caused the back kick...

SF9812DSL (recommended), SF9512DSL, SF9512DSLMS2+3 and IT pack

but the insurance pay by yearly, RM10 for Rm5k yearly, insurance wont cover back kick surge... and u need to fill up the form and list all the equipments serial number that u intend to cover by insurance...

yup, IT pack is enough for u if u needed for more sockets at the same time...

if the PC without internet / network connection, needed power source only...
SLMS2+3 or Twin Power Pack are the choices...

if with internet... SF9512DSL MS2+3, IT pack

if with internet and ur owned multi socket... SF9812DSL, SF9512DSL...

each of the RED LED indicate input and output for the power source from TNB... it still means it working fine on power source... but the LED not indicate the tel line is working or not...

u can plug with other surge protector, but maybe the broadband connection speed may decrease after filtered by several units of protector...

if all the units tat u mentioned located at the same location/same table areas...
and dont have other PC/laptop connected to wireless router by using lan cable...

MDSC0039 + SP9201DAF are recommended

yup...

wall socket
|
V
MDSC0039 -> 5-gang extension -> CPU, monitor, speaker, router, modem, etc

tel line
|
V
SP9201DAF -> telephone
|
V
modem

just ensure that dont have any back kick by lightning into ur equipment...
example : used SP9201DSL (tel line only) protect modem, but surge come from power line and strucked modem even the SP9201DSL still working...

if ur networking installation only invloved 1 set of pc and 1 unit modem/router SF9812DSL recommended... but if u have more than 1 set of pc or other unrelated PC equipments invloved, other cal-lab models will be included, and prefer draw a installation diagram and the length between equipments if possible...

if ur PC, modem and cordless phone located together...
i suggest for SP9201DAF + SLMS2+3 / MDSC0039

SLMS2+3 : 2 * 3pin and 3 * 2pin power socket
MDSC0039 : only have 1 * 3pin power socket

is it ur modem used as wireless modem only? not wired lan cable involved?

here the installation diagram according ur requirements if dont have any wired lan connection involved and assume all the equipments located at the same location.


SP9201DAF = ADSL splitter filter, replace ur current ADSL spiltter filter with cal-lab SP9201DAF. it able to protect telephone and modem at the same time. it wont interfere the ADSL bandwidth with/without the cordless phone.

SP9201DSL only used on broadband signal which after ADSL splitter filter and it dont have capability to protect analog phone. for those ppl who split after SP9201DSL, the broadband speed/connection may effected when telephone incoming and outgoing.

regarding the back kick, can refer diagram below which the surge may come from "other pc" and strike "ur pc" and "modem" even though used cal-lab products

i able to do courier...

regarding the back kick, example like u locked your house front door, but back door not locked... thief still able to go into your premise steal your stuff... i draw another diagram which is unsafe installation...

Front door : SP9201DAF, MDSC0039
Back door : not protected, from "other PC"... "thief" bypass "other PC" and "steal" ur stuff


in order to protect back door, u need another models for complete protection such as SLAN1236 for lan cable or SD-4C for other pc's lan cable and power source...

SF9512/SF9812 protect power and tel line, but it not able to protect analog phone and modem at the same time... same concept like SP9201DSL... since u said want to protect cordless phone and modem at the same time, SP9201DAF is a must model for u...

yup. power source should be protected as well. a tiny surge may damage ur equipments as well if they are sensitive on power source.

here the diagram with cal-lab units and done some modification on ur diagram
Assume u dont want to protect PC1, PC2, Laptop... and MDSC0039, SP9201DAF, SLAN1236, telephone, ADSL modem and Access Point will locate at the same location (not more than a room space)


u said only ur AP damaged by lightning, mostly ur modem designed which able "tolerate" with lightning to reduce the chances of modem damage... and the surge by pass modem and strike ur AP... otherwise surge come from power socket's earthing even u switched off...




any doubts, i will answer u... and hear ur good news...

if intended to take SP9201DAF only, but bear the risk yourself bcos there may a lot of back kick happened... SP9201DAF only protect tel line but not for power line/lan cable...

i have a forumer which insist bought SP9201DSL only... but modem get burnt...
for other forumers who purchased the recommended models, not complaint so far...
except a forumer who done the wrong installation and caused back kick after investigated by cal-lab staffs...

example:
u locked your house front door, but your house back door not locked...
u locked your car front door, but ur car back door not locked...

the surge come from the back of power line... the surge come from the back of lan cable which across the wall and floor, wall and floor contained metal material and which able to attract surge... finally surge it jump into lan cable... the longer cable, higher chances the cable charged by surge... try to imagine how the lightning come down from sky without any media, it just by pass the air like nothing...

sorry that if offended u...

Added on June 19, 2007, 8:07 pmFYI, check out belkin products... i think none of the product designed for tel line only... for sure there have the reasons why they not develop it...

if both entry not located at the same place...

for the power source from wall socket... get MDSC0039 which support up to 10A (2000w), but afraid u will overload cal-lab units since u using 10 devices... so i may need ur help to calculate to total power comsumption come from wall socket...

for the lan connection, if only have 1 lan port going into ur switch, get SD-4C or MDSC0039 + SLAN1236 to protect the power and lan cable...

possible draw a floor map regarding the entry point and how u locate ur equipments within a room?

both combination have the same protection...
the difference for SD-4D ( power + lan cable) and MDSC0039 ( power ) + SLAN1236 ( lan cable )...

if u expect for easy portable and better look... get SD-4C
if u expect for easier and cheaper replacement exchange cost... get MDSC0039 + SLAN1236 separately...

if ur lan module on SD-4C was damaged, u have to change whole unit even the power module still working...
if separately, only exchange the modules accordingly...
