TLDR: 1k ohm, 2.2k ohm, or a combination?
G’day, I’m a sparky doing a psuedo fire system on a paradox EVO192. I have a ZX8 (8 channel expansion) and a DGP-ACM12 (door controller), each with its own battery and power supply AC adaptor.
I have 9x ECO1002 photo + thermal.
1x ECO1005 thermal.
1x ECO1004T high temp thermal.
As well as 4x PIRs,
and a monitored door strike + card reader.
(= 16 zones)
an internal siren + external siren + strobe (no zone)
A accessible bathroom call point (no zone, just a buzzer & flashing LEDs)
Probably not going to use the panel tampers (no zone),
I have ECO1000BREL12NL bases for the Smokies & thermals, non-latching so they should auto reset if the trigger is cleared.
I know how to use EOL resistors to give 3 circuit conductivities: Open circuit.
Short circuit.
Resistance (1k ohm) when zone detector triggers.
The question: why did they supply 2.2k ohm resistors?
Do I make a parallel with one resistance, and series with the other, giving me 4 possible circuit conductivity statuses? Short, 1k, 2.2k, open?
Do I put the 1k in series with the contact, and the 2.2k in parallel?
