TEMPERATURE

DAY MONTH

REAL TIME

Can be ordered in HRS : MINS or HRS : MINS : SECS and can be manually adjusted or GPS Satellite synchronised,  which is accurate to +/- one millionth of a second per month.
( see TIME FORMAT below ) 

DATE

The date is displayed by   DAY – MONTH – YEAR but with the IR Remote programmer this may be changed for example to MONTH – DAY – YEAR. ( The options are explained in the IR Remote manual )

TEMPERATURE & SENSOR

A sensor is required to be fitted for this option which we would fit in the factory alongside your order specified cable length.  Two different sensors are available, one for AIR Temperature and the other for WATER Temperature.  Please consult our sales office.
The sensor is NOTa PT100/RTD sensor, so you must not fit this type of sensor.

HEIGHTS

The Clocks are available in digit heights of 2.0” (50mm) 4” (100mm) 6” (150mm) 8” (200mm) 12” (300mm) and 16” (400mm)   ( ‘ mm ‘  rounded )

VIEWING DISTANCES

The viewing distances shown below are a GUIDE ONLY and should not be relied on as actual.  They are given as a fair indication only.

( please consult the sales office as some of these colours vary in price ) 

GREEN

YELLOW

There are three mounting methods for these Clocks.

• Flush Wall/Flat Surface Mounting
• Suspension (Hanging)
• Perpendicular 

FLUSH WALL / FLAT SURFACE  MOUNTING

This is for all models,  EA5, EB5, EA10, EB10, EA15 ( there is no EB15 ), EA20, EB20.   The cases are all supplied with brackets which when fitted are hidden from view.   The Clocks can be fitted directly to a WALL or a FLAT SURFACE like a Control Panel.

The two drawings below show the appearance of the EA ( 4 digit ) and  EB ( 6 digit ) models.

The DEPTH of the EA5 and EB5 Clocks is 42mm,   the DEPTH of the other EA10, EB10, EA15, EA20, EB20 is 45mm

SUSPENSION MOUNT

Normally used for Double Sided Clocks where the case is hung down on chains from a ceiling or beam for the display to be viewed from the ground by all STAFF in an area.

ALL Models 2”, 4”, 6”, 8”, 12”, 16” 

( Consult sales office for dimensional drawings )

PERPENDICULAR MOUNTING

This method of mounting is usually used for Double Sided Clocks on a wall or post and usually in PUBLIC AREAS.

ALL Models 2”, 4”, 6”, 8”, 12”, 16” 

( Consult sales office for dimensional drawings )

ALARM OUTPUT

( Time parameter only ) 

The CLOCK ( Time ) parameter only,  has an ALARM output function.  The alarm provides an OUTPUT ( switch only ) to operate an external Sounder,  Bell or a Flashing Beacon.

The Alarm output can be programmed for up to 30 functions per day, by entering the TIME at which the Alarm needs to provide an output signal.  This can be programmed to function over a 24 hour period, weekly at the same times or at different times and different days.  Days such as weekends can be omitted.  Or at complete shut downs the Alarm function can be switched OFF.   The duration of the output can also be varied within a range of 1~59 seconds.

SOUNDER and BEACON EXAMPLE  ( usually 95-265Vac powered )

1. Basic (Standard)

This mode requires the user to enter manually the Real Time and manually adjust periodically calibration ( 6/9 months )  with the IR Remote.  For seasonal changes Summer and Winter,   the DATE must be current to co-ordinate with the software in-built Calendar.   Other features mentioned earlier are still accessible with the programmer  but TIME is not automatically adjusted.

2. GPS Time Synchronisation ( ATOMIC CLOCK DERIVED ) +   GPS – LAN  ( LOCAL AREA NETWORK )

This is probably the most popular ‘FIT and FORGET ‘mode, whereby the Clock is supplied ( as an order option ) with a Wall mounting GPS receiver module and takes its correct time from Satellite signals.   It is extremely accurate to within +/- one millionth of a second per month and determined on the basis of Atomic Standards.

It automatically switches the Clock from Daylight Saving Time ( Winter ) to Standard Time ( Summer ) and vice versa,  in any Time Zone in the world,   where such time changes are made.

The standard GPS receiver module lead length is 10 m / 32 ft but can be extended ( at extra cost ) to 50 m / 164 ft.

Advantages of GPS : – 

• Provides highly accurate Real Time
• Does not require any manual adjustment
• Does not require any connection to the Internet
• Operates GLOBALLY
• Signal reception is inbuilt in the receiver
• Single or a multiple of Clocks can linked to create a LAN network, using just ONE GPS receiver ( see below )

GPS / LAN Synchronisation

This use of GPS is ideal for installing a number of Clocks into a building which are positioned in different locations but MUST HAVE co-ordinated Time displayed at all times.

This is a LAN system ( Local Area Network ) where ANY ONE CLOCK is the MASTER and all the other clocks in the LAN are called ‘ SLAVES ‘

The MASTER Clock is a GPS controlled Clock with one receiver.

It receives its correct time from the Satellite signal and then through the network switch or switches ( depending on how many clocks are in the network ) it transmits the Time to all the SLAVES,   so they all receive the GPS correct time.

This method can be applied to as little as 2 Clocks or many Clocks.

Addionally Temperature may also be displayed on a LAN,  but usually Temperature may differ from one location to another.

3. NTP SYNCHRONISATION ( ATOMIC CLOCK DERIVED )

NTP means ( Network Time Protocol ) which is a communication protocol supporting precise, stable and safe synchronisation of Clocks with any time server through the computer network UCT,  which means ( Universal Co-ordinated Time ).   It can support the synchronisation of a large number of devices in nationally different locations through the internet. 

This may be done from  

• Your own local time server ( Internet access is NOT required )  or
• A public remote server  like GMT / UCT  ( Internet access IS required ).   You should consult an IT specialist before embarking on NTP installation

Advantages of NTP 

• Every Clock can be configured as a local NTP time server
• Provides precise time synchronisation with public NTP servers such as GMT / UCT
• Many Clocks can be synchronised from the same server
• Operation of up to 5 different time servers ( 1 primary and 4 alternatives, so if the primary server suffers failure it automatically switches to one of the alternatives 2, 3 or 4
• The NTP Time is carried out via the ETHERNET. The Ethernet circuitry is included in the circuitry of all our NTP Clocks

4. WIRELESS SYTEM

( EU / UK, but  NOT  the USA at the moment )

The wireless RADIO system is based on a transmitter that sends the time signal ( 868 Mhz ) to the clocks which must be equipped with a special radio receiver module ( by the factory ).  The radio transmitter is synchronised by a GPS receiver.

Advantages of the Wireless System

• Flexibility in clock location and installation
• No cabling required due to wireless synchronisation
• Distribution over large distances ( up to 200mtrs, depending on building layout )

5. POE Clocks (Power Over Ethernet)

only models 2”, 4”, 6”, 8” ( Consult Sales Office )

All our Clocks have an inbuilt light sensor as standard which automatically adjusts the brightness of the display on a 24 hour basis always taking into account the position of the sun in relation to the clocks location ( Indoors or Outdoors ),   cloud cover and the shortening or lengthening of daylight hours between Summer and Winter times.

At night time this feature is particularly good as it prevents GLARE to onlookers or drivers.
