Master Clocks

Master Clocks

The Master Clock is the central time source for a synchronized clock system. It receives accurate time from an SNTP/NTP server or GPS satellite, then broadcasts that time to every secondary analog and digital clock across your facility, keeping bell schedules, time zones, and clock displays perfectly in sync.

Simpli Clock carries a wide variety of Master Clocks compatible with all major secondary clock systems. Upgrade obsolete Master Clock Systems and transition from Wired Clocks to Wireless Systems seamlessly, without putting too much pressure on your budget. If you have Lathem, Edwards, Primex, Valcom or any other manufacturer's products onsite, we can find a compatible Master Clock for you.

Wireless Master Clocks: Broadcast time over patented 915-928 MHz frequency-hopping technology (or 2.4 GHz for international use) to wireless secondary clocks across one or many buildings, with no wiring required.

TalkBack Master Clocks: Two-way communication with secondary clocks. The master receives back battery levels, signal strength, alerts, and last-signal-received timestamps, letting facility managers monitor the entire system from one location.

IP-PoE Master Clocks: Power and time data delivered over Ethernet. Integrates with existing networks; each connected IP clock can be monitored and managed from a built-in web interface.

Wi-Fi Master Clocks: Time data delivered over your in-house or internet NTP server via Wi-Fi. Ideal for facilities with clocks spread far apart or multi-building campus environments.

Wired Master Clocks: Powers a 2-wire digital communication system, one wire for data and power, one for reference. Drives many secondary clocks (analog and digital) from a single converter box on 24V models.

For school bell schedules, multi-zone time displays, message clocks, and obsolete-master-clock upgrades, Simpli Clock can spec a Master Clock that fits your existing system. Contact us for compatibility and pricing.
