OPERATION OF THE OPTIONAL IP-1 ILLUMINATED PUSH BUTTON:
In order to increase product capabilities, the DL-35 has been designed to accept the IP-1, a low voltage,
Illuminated Pushbutton, that incorporates a piezo horn, as an additional means of device activation. The
IP1 is an optional accessory, that can be mounted inside the monitored compartment.
ADDED FUNCTIONALITY OFFERED BY THE IP-1
WITH THE DOOR OPEN:
IP-1 functions are dependent on the status of the Pushbutton Enable Jumper. (labeled “PB Jumper”: See
diagram on page 9).
If the Pushbutton Enable Jumper is not clipped (default), pressing the IP-1 with the door open, when a Door
Ajar Alarm occurs, will reset the alarm and restart the alarm delay timer. This can be done repeatedly and is
useful when a door is opened for a prolonged period of time, such as during loading or unloading.
If the Pushbutton Enable jumper is clipped, pressing the IP-1 with the door open when a Door Ajar Alarm
occurs, will not affect DL-35 operation. Therefore, when a Door Ajar Alarm occurs, the door must be closed to
terminate the alarm and restore normal operation.
WITH THE DOOR CLOSED:
Operation of the IP-1 with the door closed is not affected by the Pushbutton Enable Jumper. IP-1 functions
with the door closed are always as follows:
When the door is first closed, the horn in the IP-1 beeps on and off to draw attention to the IP-1 and the
Pushbutton Label. The Pushbutton Label instructs personnel inside the compartment to press the button in
order to keep the lights on with the door closed (Label is in English and Spanish languages).
1. If the IP-1 is not pressed within 40 seconds, the horn stops beeping and the lights turn off automatically
after 10 minutes.
2. Pressing the IP-1 with the door closed keeps interior lights on (or turns them on if they are off) and starts
the Automatic Panic Alarm timer (Timer delay is 20 minutes, non-adjustable).
3. If personnel remain in the compartment for 20 minutes with the door closed, the IP-1 horn begins to
beep again.
•. Re-pressing the button silences the horn and resets and restarts the Automatic Panic Alarm Timer.
This may be done repeatedly.
4. Automatic Panic Alarm: If the button is not re-pressed within 40 seconds after the IP-1 horn starts beeping
the horn and the LED on the DL-35 activate immediately to draw attention the walk-in. The Automatic Panic
Alarm is a safety feature that protects an individual who may have been injured or is otherwise disabled
inside the walk-in.
5. Manual Panic (Entrapment) Alarm: Pressing the IP-1 for 3 seconds (as described on the Pushbutton Label)
activates the LED and the audible alarm on the DL-35 as a safety feature for situations where personnel
may be trapped inside the walk-in.
Note: In all above, exiting the compartment and closing the door automatically restores normal operation.

INSTALLING THE DL-35TM AND OPTIONAL IP-1
MOUNTING:
MAGNETIC CONTACTS:
1. Installation Tip: If desired, and if door configuration permits, the switch part of the Magnetic Contacts may
be mounted inside the DL-35 enclosure. This will not affect operation of the Magnetic Contacts and will
ensure a cleaner installation.
2. Magnetic Contacts: Magnetic Contacts may be mounted with adhesive backing or provided screws.
3. Mount magnet part of Contact onto edge of door, as far away from the hinged side as possible.
4. The magnet part of the Contact may also be mounted onto the edge of the unhinged side of the door,
preferably as high on the door as possible to minimize the possibility of damage.
5. Mount switch part of Contact onto door frame, directly adjacent to the magnet, positioned so that
Contacts close (make Contact) when door is closed.
6. When mounted, gap between magnet and switch should not exceed 1.25” when door is closed.
NOTE: Steel doors may reduce this operating gap. Position accordingly.
DL-35 ENCLOSURE:
1. Remove the faceplate.
2. If switch part of Magnetic Contact is not mounted inside the DL-35, the enclosure may be mounted in
any appropriate location on the front of the walk-in.
3. If switch part of Magnetic Contact is mounted inside DL-35, position the DL-35 enclosure adjacent to
the magnet mounted on the walk-in door and mount the switch on the side wall inside the enclosure,
positioned so that Contacts close when the door is completely closed.
4. A meter or resistance scale or a continuity checker is helpful in checking Magnetic Contacts for
proper operation. A temporary power cord to the DL-35 may also be used to help in positioning Contacts
as follows: When contacts are placed properly, the LED on the DL-35 will turn on when door is open and
turn off when door is closed.
IP-1 ILLUMINATED PUSHBUTTON:
1. Mount the IP-1 inside the walk-in next to the unhinged side of the door frame.

CONNECTING THE DL-35TM AND OPTIONAL IP-1
NOTE: All line voltage and signaling wiring connected to the DL-35 through any side wall must be enclosed
in conduit with suitable fittings for connection to the DL-35 enclosure.
LOW VOLTAGE CONNECTIONS (See the 2 Green Terminal Strips inside the unit.):
1. Strip insulation on wires by approximately ¼”.
a. Terminal Strip connections is made by pressing down on the respective actuator button with a small
screwdriver and inserting the wire into the hole below the actuator.
b. Removing screwdriver pressure will clamp the wire.
c. Do not insert wire too far, as you may clamp onto insulation.
d. Tug gently on wires to make sure connections are secure.
2. Magnetic Contacts: Connected to the Door Switch Terminal Strip.
NOTE: Multiple Contacts wired in series may be used for multi-door compartments. Any door so
connected and opened or closed will be sensed by the DL-35.
3. IP-1 Illuminated Pushbutton: The Pushbutton comes with a pre-connected, 8’ length of 4 conductor wire.
Connect to the PB switch Terminal Strip observing the color code as shown on the diagram on the back
of these instructions (Left to right: Black, White, Red & Yellow.). The color code is also printed on the
DL-35 circuit board.
NOTE: The path for this wiring, or any wiring which enters the DL-35 enclosure from within the monitored
compartment, must be sealed with silicone to keep moisture out of the DL-35.
LINE VOLTAGE CONNECTIONS (Use top knockout for access.):
Connections are typically made through ½” thin wall conduit. Provide 120VAC for DL-35 operation and
connect to black and white wires (Required current: 90mA.).
1. Connect the green screw inside the DL-35 enclosure to earth ground.
a. Control contacts for lights are dry contacts, normally open.
b. Dry Contacts function as switches and the DL-35 does not provide any power to the lights being controlled.
2. Connect accordingly as shown on the diagram on page 9 using insulated female .250” connectors sized
for the gauge of wire that you are using. It is recommended that wiring be kept short, approximately 6-8”
in length.
3. When the DL-35 is being used to operate lights, a standard light switch is no longer required, and any
existing switches should be disconnected.

SETUP AND TEST
1. Apply power to the DL-35.
NOTE: If door is closed when powered up, interior lights will turn on for 10 minutes and then shut off.
This is a safety feature to insure that lights will turn back on if a momentary power failure, such as from
a thunderstorm, occurs while there are personnel in the compartment.
2. A 10 position Alarm Delay Adjust Dip Switch is provided for selecting the door ajar alarm delay and for
testing. Range: 5 minutes to 45 minutes in 5 minute increments, selectable on switches 1 through 9.
Switch 10 is a test switch, and when selected will cause the DL-35 to annunciate a door ajar condition in 5
seconds. The Test Switch is provided as a means of quickly verifying device operation. If a 5 second time
delay is desired for normal usage, the Test Switch may also be used as an operating mode.
3. Select the Test Switch and simulate various modes of operation to verify that the DL-35 functions
as intended in accordance with selected settings. Once testing is competed and operation is verified,
de-select the Test Switch (unless you are using it for desired operation) and select the desired door ajar
alarm delay using ONLY ONE of switches 1 through 9. Select only one switch or erroneous times will
result. A switch must be selected for proper operation. Selection or changing of a switch or clipping
the PB Enable jumper may be done with power on or off. Power outages will not affect user settings.
Changes made in user settings with the door opened will be stored in program memory when the door is
closed and will become active the next time the door is opened.
4. After adjusting and testing, mount the faceplate onto the enclosure using the provided screws. Installation
is now complete.
