Large indoor or outdoor analogue clock
Areas of application : reception areas, offices, hallways, factories, schools...
Description & General features :
• Indoor or outdoor (back-lit) analogue clock.
• Hour-Minute or Hour-Minute-Second display, depending on the model.
• Optimal viewing distance : 60 metres.
• Colour : white.
• Safety glass lens or optional : anti-vandalism polycarbonate crystal.
• Dial models : Arabic figures or minute notches or DIN.
• Models : quartz, 24V second, 24V minute, AFNOR, NTP.
• Lighting (outdoor clock) : low consumption LED
Movement and synchronisation :
• Quartz movement with remote keyboard
The clock is completely autonomous. The time information is provided by its own time system.
• 1/2 minute serial impulse slave movement
Slave clocks are connected to a distribution line and activated through electrical impulses sent every
½ minute by the master clock.
• IRIG-B/AFNOR coded time receiver
The coded time distribution consists in transmitting a complete time message every second: the setting on time of the receivers is realised automatically and immediately after connection to the clock line. The IRIG-B/AFNOR coded time does not transmit interference and is insensitive to other electrical interference.
• 1.5v serial impulse slave movement (for Bt radio)
Slave clocks are connected to a radio synchronisation box (BT radio) that generates electrical impulses every minute.
• 24v minute impulse
Slave clocks are connected to a distribution line and activated by means of electrical impulses
transmitted every minute by the master clock.
• Network Time Protocol (NTP)
Slave clocks are connected to the Ethernet network and powered by PoE (Power over Ethernet (consumption: 25mA at 48 V DC). The time is synchronised by the time server or the master clock using the NTP protocol: in NTP (unicast, multicast or DHCP mode).
