Enrolling, Programming and Placement
Enroll the WS4928 by programming the 6-digit serial number (located on the WS4928) into the receiver. Once the WS4928 is enrolled, you must perform a Module Placement test to ensure the location you have chosen 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 installation manuals.
Step 1 – Program Electronic Serial Number (ESN) 
Section [804], subsections [01] – [64]
[01] Zone 1 ...  [64] Zone 64
Enter the 6 digit ESN located on the WS4928 into the next available zone slot.
Step 2 – Program Zone Definition
Section [001] – [004]
Define corresponding zone with appropriate zone type [i.e., Holdup (12)].
Step 3 – Enable Wireless Zone Attribute

Turn Option [8] ON (wireless zone attribute) in corresponding zone attribute section.
All wireless devices must be tested for good signal strength from where they are positioned.
Step 4 – Device Placement Test
Section [904], subsections [01] – [64]
Activate the switch. 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) indicates BAD placement
If the transmitter tests BAD, move the transmitter and repeat the Placement Test.
Mounting the Device
Secure the holdup switch to the mounting surface using the 4 mounting screws provided. NOTE: The WS4928 may be mounted horizontally or vertically. In horizontal installations, position the unit so that the finger-operated slide is acti-
vated by pulling toward the user. In vertical installations, position the unit so that the finger-operated slide is activated by pulling downward by the user.
Operation
Activation - The WS4928 holdup switch is activated by placing a finger in the access hole and pulling the slide toward the user (downward in vertical mount installations). The alarm activation will be indicated locally at the device by the
red tab on the unit. The device will remain latched in the alarm state until a manual reset is performed. 
Restoral - To restore the device, insert the reset tool into the two rectangular slots next to the alarm indicating tab. Ensure the flat (unbevelled) side is facing the red tab (see Figure A).
Testing
1. Notify the central station prior to testing the switch.
2. Activate the switch.
3. Reset the switch.
4. Verify receipt of the alarm and restoral signal at the central station and provide notification that the test is completed.
Tamper Switch & Wall Tamper
The WS4928 comes equipped with case tamper detection. If the case is removed, the WS4928 will report a zone tamper to the control panel. For added security the WS4928 was designed to provide wall tamper monitoring as well.
When using the wall tamper please do not install the device on surfaces made of soft materials.
NOTE: A tamper switch is required for UL Listed commercial burglary/holdup installations.
Replacing the Battery
