Page 9: Planning
Planning All DuraTime wireless devices receive and re-transmit time data to other devices. This includes master clocks, analog clocks, digital clocks, alarm interfaces, repeaters and sensors. This method of repeating data allows coverage of any size of facility or campus. The rule-of-thumb for the placement of wireless devices is to locate them no further than 150 feet (45m) apart for areas with many wall partitions, such as offices, dormitories and hospitals.
Page 10 An optional GPS receiver is available for the master clock. This receiver sends the time received from the GPS satellites wirelessly to the master clock. The GPS receiver can be used in addition to NTP time for a redundant time source. Configuring the Time Zone Offset If the time displayed is incorrect after the synchronization indicator appears, then time zone rules may require reconfiguration.
Page 11 Alarm relay connections along with RS422 connections. The DuraTime RC100 master clock includes connections for power, alarm relay and Ethernet. The alarm relay includes 10 Amp contacts. Larger loads should make use of a slaved relay. There are two primary network types: Periodically Active and Continuously Active.
Page 12 recommended to plug the wall repeater into an outlet located high on the wall to prevent accidental damage or tampering. Dropped ceiling repeaters are also available. Be sure to secure the wall repeater to the electrical outlet using the RC140 Wall Repeater screw hole provided in the repeater housing.
Page 13 The RC150 Mini-Master is a high precision synchronized master clock, incorporating a temperature compensated quartz oscillator, multi-path radio transceiver and a 10 year battery to maintain the internal time. Mini-Master Clock Operation Press the yellow On/Off button to power on the unit. The LED will flash twice per second. This indicates the unit is in repeater only mode.
Page 14 To change the channel of the mini-master clock, press the On/Off button to power the unit on. Then simultaneously press the Repeater Only and Transmit Time buttons, then release. The indicator light will flicker momentarily and then go out. Next, press the Transmit Time button equal to the desired channel number.
Page 15 The wireless relay / tone generator includes a configuration dip switch. Switch position 1 sets the audio output, up=high (1 volt P-P), down=low (0.5 volt P-P). Switch position 2 sets the device function (up=audio player w/ relay following, down=timed relay). Switch positions 3-6 sets the alarm zone number (binary 1-12).
Page 16 = 12 = 13 9 10 = 10 = 14 9 10 9 10 = 11 = 15 9 10 The relay output of the master clock is always a timed or steady state, and does not follow any audio play, or zones. An internal speaker is available when the device is in audio player mode.
Page 17: Operation
Operation The DuraTime master clock obtains time updates from local or public time servers, and/or from the optional GPS receiver. The time received is used to update the master clock’s internal temperature compensated quartz oscillator. The internal clock is backed up using a 10 year Lithium battery to prevent time disruptions due to power outages.
Page 18 configured for single master clock operation. It will always transmit in this configuration, regardless of the presence of other master clocks or sync reception. By default, the LED display will cycle through several screens to display different information. Momentarily pressing the blue TC button will display various other formats. Six digit time Eight digit date This screen indicates whether the clock is a primary or secondary master clock...
Page 19 time and includes indicators for sync source and primary or secondary status. A “T” will display on the primary clock that is actively transmitting. Another available display format includes four digit time following by status indicators. A “T” will display on the primary clock that is actively transmitting. When a slave clock receives a time update, it immediately repeats the signal to all other clocks within range.
Page 20 be some time later. If a battery clock is in low power mode, removing and reinserting the batteries, pressing the receive button, or shorting the reset pins will not enable for reception. A mini-master will not help. In this case the clock must moved to a location in direct range of the master clock.
Page 21: Alarm Configuration
Alarm Configuration Each master clock has 999 total alarm settings that can be configured to activate a wireless audio alert / relay device at various times and days. For example a start lunch break alert horn could sound a constant tone for three seconds beginning at 12:00 noon, Monday through Friday.
Page 22 Enter the description of the alarm item into the box next to the Create New Alarm Record button. Be sure to press the Enter key after entering the description to confirm the entry. Next, select the day-of-the-week for the alarm to activate. Then select the time of day. Be sure to select AM or PM. Now click on the Alarm Function drop down box to view the available alarm options.
Page 23 Each wireless alarm receiver may be configured to one of twelve zones, with zone 1 the default. The alarm schedule program may be used to select any combination of the twelve zones. For example, zone 1 could be used for one area of a building and zone 2 for another area.
Page 24 When the Active Alarm Schedule number is set to 0, a date range may be used to automatically switch from one alarm schedule to another. Select a date range to use (1-20) and the alarm schedule number to activate. Then enter the desired date range.

Page 26 Clock Supervision Monitor The Clock Supervision/Monitor feature is used to interrogate clocks to determine if they are receiving and storing time updates. Only LED digital clocks are supported at this time. It does not report malfunctions with the visual display. The monitor program will test the communications link between the control PC, and between the master and between the Master clock and the slave clocks.
Page 27 The Supervision/Monitor screen includes a variety of features as described below. The database window lists the clock address, location description, master clock time/date, slave clock time/date and supervision status. The location description should indicate the location of the clock The Master Time indicates the time/date of the master clock at the time the slave clock was tested. The Slave Time indicates the time/date stored and maintained by the slave clock.
Page 28 Clicking on the Start Monitor button starts the monitoring process. The green Monitoring Enabled message will be displayed on the screen. During monitor, if a clock does not respond, or the master clock does not respond, or a clock responds with the incorrect time, an message will be displayed indicating a problem.
Page 29 The next screen shows two messages that will generate an alert message, even though the third clock is correct. An alert message will also be displayed if the slave clock time is not close to the master clock time. The monitor program must remain running while the slave clocks are monitored. The monitor program must also remain running if Auto Start Monitor is selected.

Page 47: Ethernet Communications
Ethernet Communications Overview Once the clock is connected to the network and power is applied, DHCP is used to automatically assign each clock an IP address on the network. The clock will then search the Internet or local area network for NTP time servers. NTP (Network Time Protocol) is a uniform method of sending time over a computer network.
Page 48 User Name and Password The menu in the left column allows selecting several sections of the interface. A user name and password is required to enter any section other than the main page. The default user name is: user The default password is: password The user name and password should be changed after installation.
Page 49 Clock Name - is the user defined name used to identify the device during a network search. SNTP Sample Interval - is the time in minutes between SNTP time updates. The default is one minute. SNTP Extra random delay – if this box is checked, a random delay will be added to the sample period so that all clocks to not attempt to access the time server at the same time.
