SAFRAN 2406-XYZ SecureSync Time and Frequency Reference System
Product Information
The SecureSync 2400 Master Clock is a versatile electronic device designed for defense and electronics applications. It offers precise timekeeping and synchronization capabilities, ensuring accurate timekeeping across various systems and networks.
Form Factor Options
- 2406-XYZ: Features six option card slots
- 2402-XYZ: Features two option card slots
Backup Oscillator Options
- 240W-XYZ:
- 0 = TCXO (Temperature-Compensated Crystal Oscillator)
- 1 = OCXO (Oven-Controlled Crystal Oscillator)
- 2 = OCXO LPN (Low Phase Noise Oven-Controlled Crystal Oscillator)
- 3 = Rubidium
- 4 = Rub LPN (Rubidium Low Phase Noise)
Accuracy and Holdover
The SecureSync 2400 Master Clock offers accuracy to UTC (locked to GPS) at 1
sigma. It also provides holdover stability, maintaining consistent timekeeping
even after 2 weeks of GPS lock, with specified accuracy after 4 hours and 24
hours.
Power Options
The SecureSync 2400 can be powered using two different configurations:
- Single Fixed Power 240W-XYZ:
- X options: 0 = 100-240 VAC, 3 = 12 VDC, 4 = 24/48 VDC
- Hot Swap Power 240W-6YZ:
- Requires at least one power module in addition to the base unit
- Power module options: 2400-HS-A1 = 100-240VAC, 2400-HS-D1 = 12 VDC, 2400-HS-D2 = 24/48 VDC
I/O Options
The SecureSync 2400 supports network expansion and connectivity through
optional I/O cards:
- 1204-49 Dual Nic Option Card (SFP): Provides NTP-only ports
- 1204-4A Quad Nic Option Card (SFP): Provides NTP-only ports
NENA Compliance
To meet NENA Master Clock specifications and synchronize legacy Spectracom
TimeView Display Clocks over RS-485 Terminal Block, the following options can
be added:
- SFP-Copper Module(s)
- CA08R-0000-0010 NENA Breakout Cable
- 1204-0F Alarm Relay Option Card: Enables Relay/Alarm OUT (Terminal Block) (Requires 1204-0F installed)
Accessories
Various accessories can be added to enhance the functionality of the
SecureSync 2400 Master Clock.
Product Usage Instructions
To use the SecureSync 2400 Master Clock, follow these steps:
- Choose the desired form factor option based on the number of option card slots required.
- Select the appropriate backup oscillator option based on your needs.
- Build the power configuration by either opting for Single Fixed Power or Hot Swap Power. For Single Fixed Power, populate the X with the desired power option. For Hot Swap Power, order at least one power module in addition to the base unit.
- If network expansion is required, select the desired I/O option card(s) based on your connectivity needs.
- If NENA compliance is necessary, order the SFP-Copper Module(s), CA08R-0000-0010 NENA Breakout Cable, and/or 1204-0F Alarm Relay Option Card.
- Add any desired accessories to enhance the functionality of the SecureSync 2400 Master Clock.
For more detailed setup information on specific options, please refer to the SecureSync2400_NetClock_Option_Guide_rev1 document.

Populate the X with the a power option below:
- 0 = 100-240 VAC
- 3 = 12 VDC
- 4 = 24/48 VDC
Integral power supply, ships with line cord or mating connector
Hot Swap Power
240W-6YZ
Dual Hot-Swap requires ordering at least one power module, on top of power option 6 for the base unit. Order (1) or (2) of the these power supply line items with the base unit, in any combination:
- 2400-HS-A1 = 100-240VAC
- 2400-HS-D1 = 12 VDC
- 2400-HS-D2 = 24/48 VDC

Expand Network Capacity
Order Option Card(s)
- 2400 includes two Gbe Network ports on chassis (1) RJ-45, (1) SFP.
- Add additional network cards to increase processing capacity and the number of ports from 2 (Base) to 4, 6, 8, or 10 network ports in a single 1RU chassis.
- The ethernet ports of the base chassis unit provide NTP, PTP, and Management capabilities.
- Field upgradeable.
