[Ticket Question] Dt7550Uk2 Wiring Instructions

Secware
in Intruder Alarms

Featured Replies

I bought a new DT7550UK2 from you last week to replace an existing faulty one. The existing one is a DT7550UK so assume this must be the older version.

 

Looking at the existing wiring, it is wired as follows

F1 - empty

F2 - empty

T1 - resistor to C

T2 - yellow

C - resistor back to T1 and to NC

EOL - empty

NC - resistor to C and blue

V- - black

V+ - Red

 

Both resistors have the following bands (Brown, Black, Black, Brown, Brown) or I guess could be (Brown, Brown, Black, Black, Brown)?

 

Looking at the installation instructions for the new one, it implies I should not use the existing resistors and wire up as above. Is this the case? Also, will the factory jumper settings we ok?
