Introduction
The DL50 is a keyless proximity door lock that fits most standard
doors. Simply replace your existing cylindrical style door handle
with the DL50 for an economical access control system for your
business or home. The locks provide stand alone operation and
do not require the use of a computer or any external device for
programming. They are powered by standard alkaline batteries
eliminating the need for wiring. The DL50 uses radio frequency
technology to instantly identify proximity badges and key fobs.
No transaction history is retained.
DL50 Features
User-installable access control
120 user capacity per lock
Operates for 1 year or 4,000 activations on batteries
Heavy duty all metal construction
Lighted display & audio alerts for badge authorization
Stand-alone operation - no computer required
One year warranty
Installation
Please refer to the separate Quick Start Guide enclosed with the
lock for basic installation instructions. More detailed installation
instructions, including the preparation of new doors, are
contained in the back of this User’s Guide.

Using the DL50
When a badge or key fob is placed over the reader window of
the DL50, it instantly reads its unique encoded ID number and
verifies that it has been authorized to open the door. The DL50
comes with five preprogrammed badges which can be used
immediately following installation with no additional setup
required.

Good Badge
If the badge or key fob has been programmed into to the lock,
the DL50 flashes a blue light, sounds a positive tone, and
engages the door handle to allow access. The default unlock
window to open the door is 5 seconds, but this can be
customized for each lock to 3 or 10 seconds (see Customizing
Unlock Window).
Bad Badge
If a badge or key fob has not been programmed into the lock, the
DL50 will flash a red light and a sound a negative tone. The
handle will not engage the latch and the door will not open.

Badges and Key Fobs
The DL50 supports the use of SimplexGrinnell proximity ID
badges (included with lock) or optional SimplexGrinnell proximity
key fobs that users can simply attach to their key chains. The
use of badges or key fobs is an individual user preference, and
they can be used interchangeably on any lock.
A badge or key fob can be programmed to be one of two distinct
types of users of the DL50: Master or User
Master Badges
The Master not only allows access through the door, but also
provides additional administrative rights to the holder so they can
add and remove users as needed. The DL50 supports up to two
(2) Master badges or key fobs. Each Master can add up to 59
individual Users. Therefore, the DL50 supports up to 120 total
authorized users including the two Masters. The DL50 comes
with one preprogrammed Master badge, which is identified by
the global key sticker located in the lower left corner of one of the
badges. This Master badge can begin accessing the lock and
adding or removing users as needed without any additional
programming (see Adding a Master).

User Badges
A User badge or key fob allows access through the door. User
badges or key fobs are added by a Master badge. There can be
up to 59 User badges assigned to each Master card. The DL50
comes with four (4) preprogrammed User badges. These
badges do not have the global key sticker like the Master badge.
These User badges can begin accessing the lock immediately
with no additional programming needed.

Backup Keys
The keys enclosed with your DL50 are for backup purposes in
the event of badge loss or battery failure only. Keep your keys in
a protected and easy-to-remember location. SimplexGrinnell
does not manufacture or stock extra keys. You are responsible
for their safekeeping.
1. The keyhole cover is attached using a high-powered magnet.
Your backup keys also have a smaller magnet embedded on
one side to assist in removing the keyhole cover. Or, you
can use your fingernail to pry open the cover.
2. After removing keyhole cover, place key in keyhole with
arrow and notch pointing up to align with dot above keyhole.
3. Insert key and turn to the right until key stops.
4. While key is turned, push handle down to open door.

Using Multiple Locks
If you have purchased multiple DL50s, you can configure and
change the badge accessibility to each of your locks as you
prefer. Remember that each lock is stand alone which means
you must program them individually. However, this also means
you have great flexibility to customize access to rooms as
employees or work areas change.
For example, if you want to program a User badge from Lock #1
to also access Lock #2, simply use Lock #2’s Master badge to
add it to Lock #2.
Please note: We suggest you maintain a list of which badges are
programmed to which locks (example below) and keep it
updated frequently.

Maintaining the Lock
The SimplexGrinnell DL50 is designed for years of trouble-free
operation. The only routine maintenance typically required is the
changing of batteries and occasional cleaning.
You should routinely check your batteries every few months
depending on the usage of door.
LOW BATTERY INDICATOR: When the batteries begin to run
low, you will see the Red light flash and a beep after badges are
used. You may also notice that the volume of the beeps
decreases. Change all four batteries (AA alkaline only) as soon
as possible.
Clean handle by spraying a small amount of glass cleaner on to
a towel and wipe handles with soft towel.
Periodically inspect handles for tampering, vandalism or “wear
and tear”. After a period of usage, you may find it beneficial to
retighten the connecting screws by removing the Interior handle
and using a screwdriver.
DL50 User’s Manual

Use the 4 “dimple” guides in each corner and insert them in
corresponding holes, peel away sticker and attach.
2. Install connecting pillars to Exterior handle with pillar wrench
included as shown below.

3. Insert axle into center turning hub. Make sure the “dot” is
up on the turning hub and holes are vertical on axle.
4. Insert securing pin downward thru top of turning hole, thru
axle until pin is completely thru.
5. Bend “legs” of pin outward around turning hole to secure.
You may require pliers to do this.
DL50 User’s Manual
Page 21
6. If the axle and pillars fit, you may elect to keep your current
latch in place or remove it and replace with the latch
included. Latch included is expandable up to 2 ¾”. To
expand latch, hold front of latch with one hand and pull on
center axle hub. Make sure that latch slope faces the same
direction the door closes. Secure with 2 small latch screws
provided.
7. Place Exterior handle on door: Guide wire thru door hole
over top of latch assembly. Place connecting pillars thru
latch holes and axle thru center hole. Make sure the dot is
still up on the axle turning hub.
8. Push thru and allow Exterior handle to rest in latch.
SimplexGrinnell
Page 22
9. Run wire thru rectangular opening in battery pack (to side of
center hole).
10. Secure battery pack with 2 long connector screws at each

11. Make sure Exterior handle and battery pack are straight as
you tighten connector screws.
DL50 User’s Manual
Page 23
12. Connect wire to circuit board underneath the bottom battery
on the battery pack. Observe how pins align with plastic
connector.
13. Install 4 new AA (1.5 volt) alkaline batteries (not included)
into battery pack on Interior handle. Make sure they are
installed in the correct direction and are firmly seated in
position. You will hear a buzz, indicating the lock is
energized.
14. Place Interior handle cover over battery pack and secure
with 2 screws on top and bottom. Do not over-tighten the
Interior handle! Doing so may affect the performance of the
lock.
SimplexGrinnell

Preparing a New Door
Verify that your new door is 1 3/8” – 2 1/8” (35-55mm) thick.
1. Use the enclosed “Door Cutting Template” to mark your drill
holes.
Note: Position template at correct height (suggested:
38” or 97 mm from floor). Mark center for lock hole.
2. Drill 2 1/8” hole through door. Do this by drilling once
from each side to center of door to avoid damaging door.
3. Drill 1 1/8” latch hole being sure to align the center of the
latch hole with the center of the main door hole.
DL50 User’s Manual
Page 25
Latch Installation
Use enclosed “Strike Plate Cutting Template” to cut and
install latch in door as indicated below.
1. Insert latch into 1 1/8” latch hole in “width” of door. Latch
is expandable, depending on the size of your door hole,
to 2 ¾”. To expand latch, hold front of latch with one
hand and pull on center axle hub.
2. Trace around the perimeter of the latch faceplate to
create your chisel border. Remove latch in order to
chisel.
3. Chisel out wood as indicated on template (1/8”) until
faceplate fits flat with door edge.
Important: Be sure to install the latch to match your lock
(Right or Left hand).
4. Make sure that latch slope faces the same direction the
door closes.
5. Fasten latch to door with 2 small latch screws.

Strike Plate & Dust Boot Installation
1. If you are installing on an existing door jamb, you may be
able to use your existing strike. However, it is recommended
that you use the strike included.
2. On a new door, use the “Strike Plate Cutting Template” to
mark and install the strike plate. Center the metal strike plate
over the dust boot with the curved edge facing the interior of
the room. The goal is to have the metal strike plate flush with
your door jamb.
3. Insert dust boot and secure strike plate with screws provided.
Test opening and closing of door and adjust as needed.
