WS4945
Wireless Door/Window Contact
Installation Instructions - For Service Persons Only
This Installation Manual shall be used in conjunction with the Installa-
tion Manual of the DSC wireless receiver and control panel with which
this device is intended to be used.
Powering the WS4945
For your added convenience, the WS4945 comes with the battery pre-
installed. To activate, hold the WS4945 firmly in one hand and pull the
plastic tab in the direction indicated.
Locate Transmitter
Select the location where the WS4945 is to be mounted. NOTE: RF sig-
nals can be affected by metal objects, including metal doors or large mir-
rors. Such locations should be avoided, they can interfere with proper
operation.
Enrolling, Programming and Placement
Enroll the WS4945 by programming the 6-digit serial number (located on
the WS4945) into the receiver. Once the WS4945 is enrolled, you must
perform a Module Placement test to ensure the location you have cho-
sen is suitable. The following outlines the basic steps for programming
and enrolling this device on PowerSeries receivers. For additional
options or for other receivers please refer to the specific receiver installa-
tion manuals.
Step 1 – Program Electronic Serial Number (ESN)
Section [804], subsections [01] – [32]
[01] Zone 1 ... [32] Zone 32
Enter the 6 digit ESN located on the WS4945 into the next available
zone slot.
Step 2 – Program Zone Definition
Section [001] – [004]
Define corresponding zone with appropriate zone type [Ex. Delay (01),
Instant (03), etc.].
Step 3 – Enable Wireless Zone Attribute
Section [101] – [132]
Turn Option [8] ON (wireless zone attribute) in corresponding zone
attribute section.
NOTE: All wireless devices must be tested for good signal strength from
where they are positioned.
Step 4 – Device Placement Test
Section [904], subsections [01] – [32]
Open and close the contact by moving the magnet away from the
WS4945. The panel will indicate the test result through the siren (and
also through the keypad):
• 1 bell squawk/beep on LCD keypad/LED 1 on LED keypad) indicates
GOOD placement.
• 3 bell squawks/beeps on LCD keypad/LED 3 on LED keypad) indi-
cates BAD placement.
If the transmitter tests BAD, move the transmitter and repeat the Place-
ment Test.
Mounting the WS4945 and Magnet
Once you determine the proper location (see Enrolling, Programming
and Placement), the WS4945 can be permanently mounted. It is the
responsibility of the installer to ensure that the WS4945 is securely
mounted in the intended location.
Remove the back from the transmitter. Mount
Using Provided Screws:
the back housing of the WS4945, using the screws supplied, to the
desired location.
Ensure you are attaching the WS4945 to a
Using Adhesive Tape:
painted or primed surface that is clean and dry. Apply the tape to the
back of the WS4945 and apply to the surface using firm pressure. Hold
for 10-15 seconds to ensure a strong bond. It can take up to 24 hours for
the tape to reach maximum bonding strength.
unsuitable, secure the WS4945 with mounting screws provided.
Align the magnet with the arrow
C). Mount the magnet a maximum of 5/8" (1.6cm) from the WS4945 by
using the provided tape or screws. If necessary use the spacers pro-
vided. Once the WS4945 and magnet are mounted, open and close the
window/door to ensure that none of the parts interfere with this move-
ment. Only one magnet can be used for each WS4945.
Using External Contacts
The external contact terminals can be used to connect external contacts
or other switches/devices to the universal transmitter. Install the addi-
tional device as per the manufacturer instructions. Connect the device to
If surface conditions are
on the WS4945 housing (see Figure
the contact terminals of the WS4945. The input is normally closed and is
not supervised.
The wires connecting the external device to the input terminals must not
exceed 3ft/90 cm in length, provided that the resistance of the wire does
not exceed 100 Ohms. The contact and transmitter must also be in the
same room. Only one contact can be used. If an external contact is
used, do not install the magnet.
NOTE: Ensure all wiring is stripped to 1/4" (6mm) max. and does not touch
any of the components.
Tamper Switch
Out of the box the WS4945 comes equipped with case tamper detection.
If the case is removed, the WS4945 will report a zone tamper to the con-
trol panel. For added security the WS4945 was designed to provide wall
tamper monitoring as well. Simply replace the short rubber actuator (see
Figure D) with the longer one that is included.
With this option, if the case is opened or if the WS4945 is removed from
it's location, a tamper will be sent to the control panel. It is strongly rec-
ommended that mounting screws be used when using the wall tamper
option.
When using the wall tamper please do not install the device on walls
made of soft materials (e.g. gypsum board).
NOTE: For EN compliant installations the wall tamper overall length shall be
cut to 12mm. First install a screw type M 2.5 x 6mm through the wall tamper
pipe so that the head of the screw remains inside the pipe when the back-
plate is mounted to the final location and then place the wall tamper in its
location. This will ensure tamper detection for the removal of the unit from
its mounting surface.
Replacing the Battery
To replace the battery, insert a flathead screwdriver into either side of the
unit and carefully twist to separate the top and bottom plastic (see Figure
A). Once separated, the battery will be visible (please see Figure B).
Remove the old battery and install new battery. Ensure correct polarity is
observed. Dispose of used battery promptly.
CAUTION: The battery used in this device may cause a fire or chem-
ical burn hazard if mistreated. Do not recharge, disassemble, heat
above 100°C (212°F) or dispose of in fire. Replace battery with one
3V lithium battery, Panasonic CR2 or Duracell CR2 only. Use of
another battery may present a risk of fire or explosion. Dispose the
used batteries as per local regulations. Keep away from children.
NOTE: Test unit at least once yearly.
