Resisters In Alarm Panals Little Help

[angellonewolf]

yes hello again if you are looking from last topic

just to ask resisters in pirs and panels what are they for and will panels need just the right ones

assume they are for if some trys to trick the system in to linking tampers/ pirs so they think they are stilll conected in series

eg a to b to c to d try to tamper and link a to d to cut out b and c alarm will sence this?

thanks angel

Sort of....

sort of

a bit of expansion on that please

The resistors do need to be compatible with the panel.

Different makes of panel do use different values of resistor but if you replace your existing panel like for like you won't have to replace the resitors.

can you install alarm with out resisters

Yes you can, many panels (the Texecom Veritas for example) can be programmed for use with double pole wiring so no resistors required.

FSL wiring with resistors is far more secure though and you only need a 4 core cable to a PIR instead of a 6, also with maby panels you get more diagnostic information at the panel by using FSL wiring.

Some detectors now come with built in resistors so you don't need the ones supplied with the panels. You just select the value of the apropriate resistor by selecting either a switch or a link within the detectors themselves so make sure you select the correct values and ckeck the readings with a meter as you cant believe everything you read.

aswell as being more secure, eol resistors provide you with a monitored circuit for faults, ie: short or open circuit.
