Timer Switch Control Specifications
The Primex 3 button Timer Switch Control provides the method manage events for both the Elapsed and Code Blue Timer. Elapsed
Timer count down or count up events are triggered manually by a user from the timer switch control buttons. Code Blue Timer
events are triggered by the input of the wired connection to the code blue system and the timer switch control allows a user to
pause a code blue event.
lDesigned to fit inside a single gang box (not supplied); typically 2 1⁄4 in. x 2 3⁄4 in. x 4 in. (11.45 cm x 6.99 cm x 10.15 cm).
lTimer Switch Control can simultaneously activate two connected timers for even more accurate event management.
lTimer Switch Control membrane switch and wall plate clean easily and resist common cleaners and disinfectants. Be sure to
test any cleaning solutions on a small area.

Configure Settings
Access setting panel
To change the factory default settings, remove the small rectangular access panel located in the upper center of the face of the
clock/timer. To aid in removal, there is a small recess in the top center of this panel. The panel can be removed with a small
screwdriver by gently prying the center top edge of the access panel forward. Setting changes can be made while the clock/timer
is ON and changes take effect within a few seconds.
NOTE
When power is first applied to the clock/timer or the reset button is pushed, a decimal point flashes for approximately
three minutes while the clock/timer receiver is turned on to search for a Transmitter signal. If the clock/timer does not
receive a valid signal from a Transmitter for three days its colons will flash.
Set LED Dimmer Display
The LED Display is set to 100% by factory default.
Set Dimmer to 25%
To dim the LEDs by 25% for a 2.5" display set Dimmer 2 in the UP position and for a 4" display set Dimmer 8 in the up position, as
illustrated below.
Set Dimmer to 50%
To dim the LEDs by 50% for a 2.5" display set Dimmer 1 in the up position and for a 4" display set Dimmer 7 in the up position, as
illustrated below.
Set Dimmer to 75%
To dim the LEDs by 75% for a 2.5" display set Dimmer 1 and 2 in the up position and for a 4" display set Dimmer 7 and 8 in the up
position, as illustrated below.

Set Alternating Time/Date
To set the display to alternate between Time and Date, place the HR OFFSET - Time/Date switch 8 to the up position, as illustrated
below. Switch 8 for 2,5" and Switch 2 for 4".
Set Display to 24-Hour Time
To set the display to 24-hour time: for a 2.5" display set the HR Offset, 12/24 HR switch (7) in the up position and for a 4" display
set the HR Offset, 12/24 HR switch (1) in the up position, as illustrated below.
Set PM Indicator
To set the PM dot indicator for a 2.5" display set the PM switch (3) to the UP position and for a 4" display set the PM switch (6) to
the UP position, as illustrated below.
Set Offset Hours
The Clock/Timer displays the time received from the Transmitter. The hour offset is for application use where the clock/timer is set
to display the time for another Time Zone.
12 XR Classic Series Digital Clocks/Timers Install Guide

By moving the appropriate “HR OFFSET” dip switch(s) and the direction (+/-) dip switch, any full-hour time can be displayed. The
“HR OFFSET” switch designates how many hours are offset from the current Transmitter Time Zone.
The clock reads the Hour Offset on start up, when the RESET button is pushed, and each time the clock receives data from the
Transmitter for the offset hours to go into effect.
Set Audible Buzzer (Timer Models Only)
The audible buzzer is only on the count-up and count-down timer function. To enable the buzzer feature, place the OPTIONS -
Buzzer switch (8) in the UP position, as illustrated below.
Set Receive Channel (Programmable Timer Only)
The Programmable Countdown Timer receives its time and schedule information from a Transmitter into which a schedule was
downloaded.
To select a Transmitter, set the RF Channel Switch to the corresponding Transmitter channel number, per the specifications
below. By factory default the PT/TC switch is set to the ON (up) position, which is required for programmable timer operation.

Installation Requirements
lRefer to the Important Safety Instructions before installing, operating or performing maintenance of clocks.
lBefore installing a clock, verify the system Transmitter is operating properly and sending a signal with adequate building
coverage.
Broadcast (Transmit) Schedule Transmitter with Internal Antenna: broadcasts its synchronized time continuously to the system
clocks and devices.
Broadcast (Transmit) Schedule Transmitter with External Antenna: broadcasts its synchronized time to the system clocks and
devices from the 39th to the 6th minute of the next hour and changes to a standby mode during the 7th to the 38th minute of
the hour (standard broadcast schedule). During initial power-up, the Transmitter broadcasts for 8 consecutive hours. After the
8 hour power-up period, the Transmitter reverts to its timed broadcast schedule.
lClocks must be installed at a location within adequate transmission range of the Transmitter.
lVerify the clock's settings have been configured before the clock is installed.
lAny damage to the clock due to improper wiring voids the warranty. It is at Primex discretion as to whether damage to the
clock was caused by improper wiring.

120VAC Wiring
Primex Classic Digital Clocks/Timers are shipped from the factory with either a plug or pigtail for permanent installation.
NOTE
Pigtail installation requires a 120V~ power line in a junction box installed by a licensed electrician. Leave a minimum of 6
in. (15 cm) of cord inside the junction box.
24VAC Wiring Guidelines
Primex Digital Clocks/Timers operate at a maximum current draw of 700mA (24VAC) and operate over a range of 20 - 26VAC.
For installations where 24VAC wiring exists - the gauge/length of the wire and rating for the supply transformer should be
verified to ensure adequate current supply and voltage for all connected devices.
For new installations - the supply wire gauge should be determined to ensure acceptable voltage drop based on installed length
from the supply transformer to most distant clock to ensure minimum voltage (20VAC) is assured.
Follow all National and Local Building Codes when installing clocks.
1. Be sure the 24VAC wiring is routed through the cable hole in the rear of the clock.
2. If a back plate is used, feed the 24VAC wiring harness through the back plate and attach it to the clock.
3. Hang the clock/timer vertically on one of the mounting screws.
4. Connect the 24VAC wiring harness. Use two wire nuts, sized appropriately for the gauge of wire, to secure the wires.
5. Finish hanging the clock/timer horizontally.
18 XR Classic Series Digital Clocks/Timers Install Guide

Surface Mount Installation
Complete the instructions below to install a Classic Series Digital Clock/Timer directly to the surface of a wall.
Installation
Mount the clock/timer directly to the wall with the two #10 screws and anchors (supplied).
NOTE
Most building codes prohibit the use of hard-wired power connections for devices that can be removed without tools.
Clock/timers mounted directly to a wall must have standard power plugs.
