Child Clocks

A 3110 Child Clock

Link up to three additional clocking points (child clocks) to your parent CS TimeClock, at a fraction of the cost.

Child Clocks can be used for time and attendance, access control and job costing.  They are in fact perfect for job costing stations or access control on doors.

*Job Costing requires TNA software.



  • Up to 3 child clocks can be connected to a parent clock.
  • Uses RS-485 communications and can therefore be up to 1000m from the parent clock.
  • Child Clocks do not have to match the model of the parent clock - you can mix and match according to your needs.
  • The 2x4 child clock can be mounted into the socket of a light switch, making it unobtrusive, yet it can still trigger a relay and have two readers.
  • The cover plates for the 2x4 readers are available in almost any colour.
  • Child Clocks have no external USB port.
  • Child clocks are only available in the PIN/Proximity models.
