Analogue clock only for indoor area
Areas of application : reception areas, offices, hallways, factories, school
Description
• Analogue display clock.
• Hour-Minute or Hour-Minute-Second display depending on the model.
• ABS casing IP 40, IK02 (indoor use).
• Optimal viewing distance : 20m.
• Poly methacrylate protective crystal (PMMA).
• Front casing colours : black, white, aluminium paint or chrome-plated metal.
• Dial markings : Arabic figures or minute notches or DIN.
• Wall bracket with optional locking system.
• Quartz 1.5v
The clock is completely autonomous, the time information is provided by its own time system.
• 24v minute impulse
Slave clocks are connected to a distribution line and activated through electrical impulses sent every minute by the master clock.
• 24v second impulse
Slave clocks are connected to a distribution line and activated through electrical impulses sent every second by the master clock.
• 1/2 minute serial impulse
Slave clocks are connected to a distribution line and activated through electrical impulses sent every ½ minute by the master clock.
• AFNOR
The coded time distribution consists in transmitting a complete time message every second: the time on the receivers is automatically and immediately set after connection to the clock line.
The AFNOR coded time does not interfere with other transmission, and is insensitive to other electrical interference.
Consumption TBT: 10 mA (6 VDC), 8 mA (24 VDC).
• Network Time Protocol (NTP)
Slave clocks are connected to the Ethernet network and powered by PoE (Power over Ethernet).
The time is synchronised by the time server or the master clock over the Ethernet network in unicast, multicast or DHCP mode.
• Network Time Protocol (NTP) silent
Slave clocks are connected to the Ethernet network and powered by PoE (Power over Ethernet).
The time is synchronised by the time server or the master clock over the Ethernet network in unicast, multicast or DHCP mode.
The second hand’s movement is continuous. The advantage of this clock is its very low noise level (<20dB at 1 metre).
• DCF radio
The clock is completely autonomous. The DCF radio synchronised movement provides absolute accuracy and automatic summer/winter changeovers.
• DHF
The DHF clocks pick up the time signal sent by the master clock via a radio signal and synchronise automatically. If radio reception is poor, the clocks keep time thanks to their own time systems.
Consumption TBT: from 15mA at 6V to 8mA at 12V to 7mA at 16V.
