Description

Sapling’s new SMA 2000 series master clock enables a user to have complete flexibility over their system. The SMA 2000 comes standard with (S)NTP capability for synchronization to pre-programmed (S)NTP web servers. The clock has two pre-programmed relays that are dedicated for synchronous wired clock systems. The master clock can be purchased with a built-in transmitter for sending out the signal wirelessly to Sapling wireless analog and digital clocks. A GPS can be added as a supplement to the already feature-rich clock for even more accurate timekeeping.The SMA 2000 also encompasses a fully functional web interface for controlling the master clock from any computer on a network or via a crossover cable. As an optional feature, the master clock also has the ability to have its own (S)NTP server that other devices can point to in order to receive time via (S)NTP.

SMA 2000 Standard Features

• Available in rack or wall mount housing
• LED display for a clear, accurate read out
• 12 or 24 hour display (Backlit LCD display 3000 model only)
• Two buttons for programming (2000 model) or 2 x 8 rubber button keyboard for easy programming (3000 model only)
• Intuitive built-in web interface that allows the system administrator to configure all the settings of the SMA Series Master Clock easily from the
convenience of any computer on the same network
• RJ45 input for web interface and synchronization to any (S)NTP/NTP server
• Ability to store up to 10 different NTP server IP addresses or domain names for continuous accurate time and redundancy
• Automatically switches from one accurate time source to another in case of a communication failure
• Blinking LED on master clock front panel to visually indicate a communication failure with the NTP server or GPS time source
• The master clock can be programmed to send an email alert when communication with the accurate time source has failed, when the master
clock has been rebooted, when the fire alarm in the facility has been activated (if applicable), and more
• Control wired clock systems or wired and wireless clock systems simultaneously, if equipped with a transmitter
• Automatic fully customizable Daylight Saving Time updates, if applicable
• Bias seconds option – offsetting the master clock to adjust the time plus or minus a few seconds or minutes to fit the application, while it is still
receiving accurate time input
• DHCP Capable
• Two relays for simultaneous correction of two synchronized wired systems:
• EX: 58 minute, 59 minute protocol, National Time / Rauland or Dukane protocol
• Proprietary RS485 input and output for time synchronization
• Can command digital clocks to say “Fire” when the alarm system interfaces with the master clock (not applicable when using a sync-wired system or an IP system)
• Microprocessor based
• Ten year battery backup for keeping time and master clock settings

Optional Features

• GPS input for accurate time synchronization
• Transmitter for the Sapling Wireless System
• NTP server upgrade
