Common questions

Which speaker cable do I need?

Thicker cable loses less power over long runs. For 100V line systems a modest size works over long distances; for 4 or 8 ohm speakers keep runs short or step up the conductor size.

What size inverter do I need?

Add up the watts of everything you will run at once and choose an inverter rated comfortably above that, allowing extra for motors and devices with a high start-up current.

Yes. We ship nationally across the UK. Call 01902 902251 or email sales@zenithsecurityco.co.uk for help.
