Shop here for expansion kits for your existing ARCT-brand system.
Expansion kits consist of a quantity of pagers, or pagers along with all the parts needed to expand the charging system as well.
For example, the ARCT 10-pager staff system has a 10-slot charger. The 5-pager expansion kit adds 5 pagers, numbered 11-15, and a charger base that adds 10 more slots.
When you are adding more pagers to your system, it is extremely important to have enough charger capacity for all the pagers being charged. Pagers that aren't being charged properly because of an overloaded charger will appear to malfunction.
