Synchronized Clocks

Analog Clock

WIRED / WIRELESS CLOCK SYSTEMS

Keeping your facility running effortlessly, on-time and in-sync.

Dukane® Master Clocks easily interface to paging and intercom systems such as the Dukane® CH1000(LT) and legacy Dukane StarCall and MCS350 communication systems for tone generation and audible signaling of bell schedules.

They also conform to the open communications standard adopted by the ZigBee Alliance of manufacturers, giving them compatibility with a wide range of wireless automation platforms available today and in the future.

Choose a wired system for new installations, a wireless system for retrofit installations or a combination of both for complete flexibility. A wide selection of analog and digital clocks are available with a range of mounting and installation options.

Dukane® clock systems deliver accurate, reliable, user-friendly and cost-effective timekeeping and communication.

Master Clock (24ZBMC100)


  • Configure Master Clock with Dukane’s exclusive browser-based Master Clock setup
  • Wired or wireless (ZigBee transmitter/receiver) signal delivery to secondary clocks
  • No limit to the number of secondary clocks on a wireless network
  • Connect to local area network with a standard Cat5, Cat5e or Cat cable with an RJ45 plug
  • 19VDC power adapter


The Master Clock is an on-site, central rack-mounted controller. It can act as a stand alone clock or receive highly accurate time codes from an NTP (Network Time Protocol) or GPS (Global Positioning System) sourceand relays these codes to local secondary clocks via a wired or wireless signal. The Master Clock broadcasts time and date signals to secondary clocks once per second.

The Master Clock easily interfaces to paging and intercom systems such as the Dukane® CH1000(LT) and legacy Dukane StarCall and MCS350 communication systems for tone generation and audible signaling for bell schedules.

The Master Clock supports four dry contact relays for activating bells, lamp controls, or other devices. Each relay can be programmed with up to 48 time-based events.

The Master Clock is configured via computer connected to the local area network using Dukane’s exclusive browser-based Master Clock setup. Simply log into the Master Clock for intuitive on-screen configuration. Many settings can also be configured using the front panel buttons.

24ZB20

2" Digital Clock (24ZB20)


  • Highly visible 2-inch LED display
  • Selectable LED display intensity
  • 12 or 24-hour format
  • High efficiency
  • Replaces the 24F750A or 24D20(A)
  • ESD-hardened
  • ZigBee Wireless capable (24ZB2040)
  • 24VAC or 15VDC operation


The Dukane® 24ZB20 2-inch Digital Secondary Clock provides a highly visible, even-intensity, long-life display of time in selectable formats. It can be operated in either 12 or 24-hour format and at either Bright or Normal intensity levels.

The time display on the secondary clock updates to the Master Clock time at one-minute intervals. This ensures that all system clocks are in precise synchronization and that every clock in the system is as accurate as the Master Clock. The high-efficiency 24VAC design allows many clocks to be operated at great distances from low cost 24VAC power supplies.

24ZB40

4" DIGITAL CLOCK (24ZB20)


  • Highly visible 4-inch LED display
  • Selectable LED display intensity
  • 12 or 24-hour format
  • High efficiency
  • Replaces the 24F750A or 24D40(A)
  • ESD-hardened
  • ZigBee Wireless capable (24ZB2040)
  • 24VAC or 15VDC operation


The Dukane® 24ZB40 4-inch Digital Secondary Clock provides a highly visible, even-intensity, long-life display of time in selectable formats. It can be operated in either 12 or 24-hour format and at either Bright or Normal intensity levels.

The time display on the secondary clock updates to the Master Clock time at one-minute intervals. This ensures that all system clocks are in precise synchronization and that every clock in the system is as accurate as the Master Clock. The high-efficiency 24VAC design allows many clocks to be operated at great distances from low cost 24VAC power supplies.

24ZBP12R

12-Inch Analog Secondary Clock – Plastic (24ZBP12R)


  • Black ABS plastic housing
  • 12-inch round
  • Wall mounted
  • 12-hour face
  • Battery and/or 24VAC power
  • ZigBee Wireless


The 24ZBP12R Wireless Analog Clock is a 12 in. (30 cm) round, wall mounted, secondary clock available with a standard 12-hour face. The clock runs on battery and/or AC power and is accurate to within ±0.2 seconds per day.

The clock synchronizes with the 24ZBMC100 Master Clock. The clock automatically adjusts for daylight savings time (DST) through the Master Clock.

24SC12R-SPL

12-Inch Analog Secondary Clock (24SC12R-SPL)


  • Replaces many popular analog secondary clocks from various manufacturers including Dukane/Edwards 24SS, Lathem SS, Simplex 77, National, Rauland 2460, Cincinnati D8, Faraday, Honeywell, and more.
  • Can be directly connected to the wiring for the Dukane® 24ZB20 2-Inch and 24ZB40 4-Inch Digital Secondary Clocks and Dukane/Edwards 24D20/A and 24D40/A Digital Secondary Clocks.
  • Allows use of both analog and digital clocks
  • Flush or surface mount
  • Ceiling or wall double-face clock
  • Shatter resistant
  • Works with Dukane® Master Clock (24ZBMC100), Dukane® CH1000(LT), Dukane StarCall, and Dukane MCS350 systems


The 24SC12R-SPL Analog Secondary Clock combines the advantages of a long-life quartz movement with microprocessor technology to provide a round 12-inch analog clock with contemporary styling.

The 24SC12R-SPL allows the use of both analog and digital clocks on the same line and it can emulate the correction schemes of many popular analog secondary clocks from various manufacturers. This allows the 24SC12R-SPL to be used as a replacement for failed clocks in many systems.

The 24SC12R-SPL is designed to be flush or surface mounted while requiring no special backboxes or mounting hardware. It can be mounted as a ceiling or wall double-face clock.

The shatter resistant 24SC12R-SPL has a single piece black metal rim with a convex acrylic lens.

24ZBP12R-DBLM

12-Inch Dual Face Clock with Mounting (24ZBP12R-DBLM)
