Universal Time Delay Module INSTALLATION INSTRUCTIONS
™
Section 1
General Description
The TDM is a multipurpose timing module that can be
used for a variety of applications. Its unique design and
open architecture allows the TDM to be used in any
application that requires timing control of up to two
outputs with up to four inputs. Common applications
include: simple time delay, vestibule door sequencing
(only one device required) and electric lock/automatic
door operator sequencing.
The four inputs on the TDM allow sequencing or
independent operation of the two outputs. Input 1 will
sequence Outputs 1 then 2. Input 2 will sequence
Outputs 2 then 1. Input 3 will operate Output 1
independently. Input 4 will operate Output 2
independently.
Both outputs on the TDM are fully programmable for "on
time" duration as well as the delay time between the two
outputs from 0 to 99 seconds.
WARNING: Devices to be controlled by the TDM
must be low voltage (12-24V) but can be
!
inductive loads. Surge suppressors are standard
on the TDM.

WET/DRY CONTACT OPTION:
The TDM has the option to supply power to Relay Output
1 contacts. This is known as having a "Wet" contact
instead of the conventional "Dry" contact closure. To use
output 1 as a "Wet" contact, change the jumper setting
(see Figure 1). The voltage supplied to Output 1 will be
the same as the voltage supplied to the input power wires
of the TDM.
WARNING: Changing jumper settings to enable
the “Wet” Contact option will apply a voltage to
!
the Output 1 relay contact. Please ensure that
any device connected to this output is capable of
accepting voltage. Failure to do so may result in
damage to the device.

Detailed wiring and programming instructions for three
common applications are included.
Once the TDM has been wired for the above application, programming of the device is as follows:
1) Apply power to the unit, provided there is no smoke or fire, you can assume that your wiring job must
be somewhat successful.
2) Once properly powered, the display will flash double bars (––) indicating that the unit is in its normal
operating ready mode.
3) To begin programming, depress the PROGRAM MODE BUTTON one time. The first parameter to be
programmed will appear on the display. This is the delay time, or "on time" of the output #1 and is
displayed as d1 followed by the time setting (It will flash between the two). To adjust the time setting,
use a small screwdriver and rotate the DISPLAY ADJUSTMENT clockwise to increase and
counterclockwise to decrease the time setting. After the desired value is displayed, depress the
PROGRAM MODE BUTTON again to save the value. The display will now read d2. Now wait 30
seconds until the display again reads double bars (––) indicating that the unit is in its normal
operating ready mode.
4) You are now ready to test your installation. If the time delay has to be changed, make the change to
the d1 setting, press the PROGRAM MODE BUTTON once and then wait 30 seconds until the double bars (––) appear again.
5) During operation of the unit, the display will indicate its operating status. Please refer to Figure 5 at
the end of this installation manual.

2) To begin programming, depress the PROGRAM MODE BUTTON one time. The first parameter to be
programmed will appear on the display. This is the delay time, or "on time" of the output #1 and is
displayed as d1 followed by the time setting of 2.0 (Factory Setting) which indicates 2.0 seconds (It will
flash between the two). This is the time duration that you want the Electric Lock released (It's usually
set around 2-3 seconds). To adjust the time setting, use a small screwdriver and rotate the DISPLAY ADJUSTMENT clockwise to increase and counterclockwise to decrease the time setting. After the
desired value is displayed, depress the PROGRAM MODE BUTTON again to save the value. The display will now read d2. d2 is the delay time or "on time" of output #2. This is the time setting that
you want for the door (operator) to remain open. This is usually set around 3-5 seconds. To adjust the
setting, rotate the DISPLAY ADJUSTMENT until the desired value is displayed and then depress the PROGRAM MODE BUTTON. The display should then read d3. This is the setting for the delay time
between the release of the Electric Lock and the opening of the door. This time is usually set around
0.5-1 second. Again, adjust the setting and then depress the PROGRAM MODE BUTTON. The display
should now read d4. Now wait 30 seconds until the double bars (––) appear, indicating that the unit is
in its normal operating ready mode. *NOTE: d1 should be longer than d3.
3) You are now ready to test your installation. If any of the time settings need to be changed, make the
change and press the PROGRAM MODE BUTTON once to save the new value. Then wait 30 seconds
until the double bars (––) appear again, indicating that the unit is in its normal operating mode.
4) During operation of the unit, the display will indicate its operating status. Please refer to Figure 5 at
the end of this installation manual.

(It's usually set around 4-5 seconds). To adjust the time setting, use a small screwdriver and rotate
the DISPLAY ADJUSTMENT clockwise to increase and counterclockwise to decrease the time setting. After the desired value is displayed, depress the PROGRAM MODE BUTTON again to save the value.
The display will now read d2. d2 is the delay time or "on time" of output #2. This is the time setting
that you want for the exterior door to remain open. This is usually set around 4-5 seconds. To adjust
the setting, rotate the DISPLAY ADJUSTMENT until the desired value is displayed and then depress
the PROGRAM MODE BUTTON. The display should then read d3. This is the setting for the delay time between the activation of the interior door and the exterior door. This time is usually set around
1-4 seconds. Again, adjust the setting and then depress the PROGRAM MODE BUTTON. The display
should now read d4. This is the delay time between the opening of the doors going in the opposite
direction. Adjust this value in the same manner as before. When the PROGRAM MODE BUTTON is
depressed, i1 will then be displayed. Now wait 30 seconds until the double bars (––) appear, indicating that the unit is in its normal operating ready mode.
3) You are now ready to test your installation. If any of the time settings need to be changed, make the
change and press the PROGRAM MODE BUTTON once to save the new value. Then wait 30 seconds
until the double bars (––) appear again, indicating that the unit is in its normal operating mode.
4) During operation of the unit, the display will indicate its operating status. Please refer to Figure 5 at
the end of this installation manual.
When the unit is operating, the display will indicate which output is active for the duration of its
programmed time delay. For relay output #1, a 1 will be displayed and 2 will be displayed for relay output
#2. If the delays d3 or d4 are used (such as an installation using a Mag Lock or a Vestibule application),
the delay will be evident between the displaying of both outputs.
In addition to the settings already described in the previous sections, below is a listing of various options
which are programmable on the TDM. The LED display vs. function are as follows:
–– = Ready Mode (flashing)
d1 = Time Delay or "ON TIME" of relay output #1—0.0 to 99 seconds
d2 = Time Delay or "ON TIME" of relay output #2—0.0 to 99 seconds
d3 = Time Delay between d1 and d2—0.0 to 99 seconds
d4 = Time Delay between d2 and d1—0.0 to 99 seconds
i1 = Switch Input #1—(N.O. or N.C.)
i2 = Switch Input #2—(N.O. or N.C.)
i3 = Switch Input #3—(N.O. or N.C.)
i4 = Switch Input #4—(N.O. or N.C.)
o1 = Relay Output #1—(N.O. or N.C.)
o2 = Relay Output #2—(N.O. or N.C.)
- - = Error (flashing)
The PUSHBUTTON FAULT INDICATOR is a special feature designed to alert the installer if a pushbutton is
"stuck" in the active position or if the wires have shorted. If this occurs, the display will flash double dots
(..). Additionally, this could mean that the wiring did not match the programmed parameter. In other
words, the unit may be programmed for use with a normally open switch, but may be wired to a normally
closed switch. Normal operation will resume once the fault condition has been cleared.
WET/DRY CONTACT OPTION:
The TDM has the option of supplying power to relay output #1 contacts. This is known as "WET" contacts
instead of the conventional "DRY" contacts or simple contact closure. Providing this voltage can simplify
the wiring of installations where an Electric Locking device is used. However, the voltage supplied to the
output is the same voltage supplied to the input of the TDM and must be compatible with the Locking
device to be controlled. Please contact the factory for additional information.
