security magnetic contacts Questions
What type of cable to be used for each following system?
I'm a fresh engineer in M&E consultant. Often I have to design various ELV and security system but I have not very sure what cable needed to used in the applications. Can anyone please help me to get clear what type of cable to be used in the following system?
a) CCTV
b) Door Access (EM Contact, card reader, push button)
c) Public Address System (Ceiling speaker)
d) Security alarm (Magnetic alarm contact, siren)
Thank you.
Normally we use fiber optic cables, it is more reliable , but normal electric wires can be used , all these considered low voltage
