FRANKLIN MARK 4

FRANKLIN MARK 4 analog clocks combine the reliability of a quartz movement gear train with a solid state micro-controller to achieve a low voltage energy efficient clock with multiple correction schemes.

ECONOMICS:

• Affordable initial acquisition cost.
• Reduced power consumption
• Low voltage plenum cable
• 24 volt models require no conduit
• Mounts to a standard one-gang electrical box, no need for special back boxes or mounting hardware.

ENGINEERS SPECIFICATIONS:
MARK 4 secondary clocks are compatible with popular master clock systems using a 3-wire synchronous scheme. Connect to a power source and master clock and the MARK 4 will automatically correct it’s minute and second hands each hour and perform a full 12-hour correction twice daily. Errors due to power failures and Daylight Saving Time are automatically adjusted.

MK 5M TRUE SLAVE ANALOG SECONDARY CLOCKS

MK 5M two hand true secondary clocks are powered and directly controlled from the master clock. A bi-stable rotary stepper motor insures minute indexing each and every minute. This positive drive method guarantees constant synchronization, not associated with any other minute impulse discipline.

Mark 5M is a system of true secondary clocks maintaining constant accuracy through 2-wire bi-polar technology.This eliminates the need for individual clock correction inherited by outdated impulse systems. This feature is available in conjunction with the fine line of FRANKLIN MASTER CLOCKS which include the WDP M + S Master Clock and Event Programmer, the Quartz F Master Clock, or the WDP – Q Mini Master Clock. Also available as Mark 5S with a second sweep hand

MARK 5M FEATURES:

• Full Number dial
• Round dials in 8″, 12″ or 16″ Diameter
• Square dials in 9″, 12″ ir 16″ Dimensions
• Light, high impact plastic molded cases in Brown, Black or Gray
• Quiet, dependable operation
• Wiring connectors included
• Shallow profile – no backbox required
• Optional wall mount/security bracket
• Optional double mount (two sides)
• Metal case with high impact plexi – glass lens available

ENGINEERS SPECIFICATIONS:

• The bi-polar minutes impulse analog secondary clock(s) shall be FRANKLIN MARK 5M furnished or installed as designated in the plans or purchase order. Each clock shall be of (specify dimension) size having a (specify shape i.e round or square) style case.
• The dials shall be imprinted with (specify number with minute marks, hours and minutes marks only or 12/24 hour numbers) and to be visible at a distance of (specify distance according to dial size selected) feet at ambient lighting conditions.
• The Franklin MARK 5M clock will display time in 12 hour format. Electrical connections will be made in accordance with local prevailing electrical codes and to a built – in terminal connector.TECHNICAL

MK 7M SECONDARY CLOCK – RETROFIT/REPLACEMENT MODEL

MK 7M two hand secondary clocks are powered and driven from the master clock. A ratchet and pawl mechanism coupled to electrical swithcing provides indexing each minute and hourly correction by rapid impulsing. This model retrofits 2 or 3 wire 58th or 59th minute corrective systems, such as Simplex, Cincinnati, Stromberg, Amano and many others.

Mark 7M is devoted to minute impulse corrective clocks, via SR-2 (2 wire) or SR-3 (3 wire) interconnection. The WDP M + S includes a permanently programmed mode for either 58th or 59th minute hourly correction reference. This system is especially suited for applications where the Master Clock controls time and attendance recorders. It is a simple matter to intermix all kinds of time display and or recorder equipment into this system and control general clock system equipment at the same time. Integrated programming of many other functions may be done simply and efficiently with this clock system and the WDP M + S master clock.

MARK 7M FEATURES:

• Full Number dial
• Round dials in 8″, 12″ or 16″ Diameter
• Square dials in 9″, 12″ or 16″ Dimensions
• Light, high impact plastic molded cases in Brown, Black or Gray
• Quiet, dependable operation
• Wiring connectors included
• Shallow profile – no backbox required
• Optional wall mount/security bracket
• Optional double mount (two sides)
• Metal case with high impact plexi – glass lens available

TECHNICAL SPECIFICATIONS: 

• Discipline: Minutes impulse with hourly correction 59th minute (58th on request) 2 – wire (SR2) or 3-wire (SR3) systems
• Electrical : 24 VDC Impulse Current at 30 mA
• Dial sizes: 8″ , 12″, 16″

ENGINEERS SPECIFICATIONS: 

• The minutes impulse, hourly corrective analog secondary clock shall be FRANKLIN MARK 7 Series furnished and installed as designated in the plans or purchase order.  Each clock shall be of (specify dimension) size having a (specify shape i.e round or square) style case.
• The dial shall be imprinted with (specify number with minute marks, hour and minute marks only or 12/24 hour numbers)  and to be visible at a distance of (specify distance according to dial size selected) feet at ambient lighting conditions.  The clock will be wired to fit a (specify 2-wire or 3-wire)  system using (specify 58th minute or 59th minute) correction.  Electrical connections will be made to provided terminal connector.

MK 8S TRUE SLAVE ANALOG SECONDARY CLOCKS

MK 8S three hand true secondary clocks are powered and directly controlled from the master clock. A bi-stable rotary stepper motor insures second indexing each and every second. This positive drive method guarantees constant synchronization, unlike any other system featuring a sweep second hand.

MK 8S this concept operates on the principle of bi-polar impulse each second, for driving the secondary clock movement, which eliminates the need for individual clock correction and provides constant accurate displayed time. This system operates using either the WDP M+S or the Quartz F Master Clock. It couldn’t be simplier or less expensive. Integrated programming of many other functions may be done simply and efficiently with this clock system and the WDP M+S master clock.

MK 8S FEATURES:

• Full Number dial
• Round dials in 8″, 12″ or 16″ Diameter
• Square dials in 9″, 12″ or 16″ Dimensions
• Light, high impact plastic molded cases in Brown, Black or Gray
• Quiet, dependable operation
• Wiring connectors included
• Shallow profile – no backbox required
• Optional wall mount/security bracket
• Optional double mount (two sides)
• Metal case with high impact plexi – glass lens available

ENGINEERS SPECIFICATIONS:

• The bi-polar seconds impulse analog secondary clock shall be FRANKLIN MARK 8S furnished and installed as designated in the plans or purchase order. Each clock shall be of (specify dimension) size having a (specify shape i.e round or square) style case.
• The dial shall be imprinted with (specify number with minute marks, hour and minute marks only or 12/24 hour numbers) and to be visible at a distance of (specify distance according to dial size selected) feet at ambient lighting conditions.
• The FRANKLIN MARK 8S clock will display time in 12 hour format. Electrical connections will be made in accordance with local prevailing electrical codes and to a built-in terminal connector.
