Information you will not find anywhere else...

You can theoretically run 32 bells, plus 16 analog clocks, and unlimited digital clocks off of the 7000, And 32 low voltage Pyramid bells off the 5300.  It's not that easy.  So we did the research.

Pyramid digital clocks self-amplify the time signal and forward it to the next clock via the company's proprietary BCD cable.  You must have a digital clock (or a 5300 signal amplifier) every 200' for this to work. BCD cables connect with Pyramid's again propretary "Y" connector - which we will supply to you as many as you need at no charge (nickels and dimes).

Pyramid's 13" dial face "analog" clocks do not have this signal amplification feature.  So, every 200' or 8 clocks - whichever comes first - you need to add/purchase a PTR5300 power supply.  This amplifies the time signal and allows you to extend the range.

Bells:  Pyramid low voltage bells are 24VAC and draw a very small amount of amps.  Somewhere in the range of 100M/a.  1000M/a is 1 Amp.  When you hit 250' or so, and several bells, it will start to get quiet.  We now offer a power booster that you would connect inline, adding a fresh 1 amp and 24volts DC to run additional bells as needed.

Work with people who obsess over the details - so you don't have to.
