Information you will not find anywhere else...

Run 35 bells, 8 analog clocks, and/or 200 digital clocks off of the 7000.

Pyramid's analog clocks require signal amplification after 8 clocks, requiring a PTR5300 power supply.  This amplifies the time signal and allows you to extend the range.

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