SD-304C PG2
PowerG, Wireless Shock and Contact detector
with Wired Input
The SD- 304C PG2 is a wireless PowerG innovative shock detector with optional magnetic contact and
auxiliary input interfacing with all PowerMaster control panels, version 16 or higher. The SD-304C PG2 fits
windows, doors, walls or roofs and is ideal for residential or commercial installations. It detects and analyzes
gross attacks or a series of low level shocks (up to 10 low level shocks within 30 seconds) and provides early
warning of any attempt of intrusion before a burglar actually breaks-in.
The detector incorporates:
• A shock / vibration piezoelectric sensor.
• Optional reed switch (with optional anti-mask sensor to prevent attempts at disabling it with an extra
magnet).
⚫ Optional auxiliary input to use with installer supplied contacts or other wired devices.
Installer added-value features:
• Digital display enables fast and easy shock level adjustment
• Full remote configuration from PowerMaster control panel or Monitoring Station saves the need to
physically access the shock detector for configuration
• Remote view of: Low Battery, front and back Tamper, Supervision
• An LED lights whenever alarm or tamper events are reported (the LED does not light while a supervision
message is being transmitted).

Refer to the Shock Detection Radius, in the Specifications section, according to the surface material used. Install the device in a location where a
strong shock impact is expected. The unit should be mounted on a flat surface and firmly fixed using both mounting screws.
For magnetic contact detection, it is highly recommended to attach the detector to the door or window on the fixed frame and the magnet to the
movable part (door or window). For optimal magnetic sensor activity and better security it is recommended to apply the magnet as close as
possible to the
detector’s marked side.
Note: Once the cover is removed, a tamper message is transmitted to the control panel. Subsequent removal of the battery prevents transmission
of "TAMPER RESTORE", leaving the detector in permanent alert. To avoid this, press the tamper switch while you remove the battery.
Caution!
Risk of explosion if battery is replaced by an incorrect type. Dispose of used battery according to manufacturer's instructions.
Attention! The unit has a back tamper switch (optional) under the PCB. As long as the PCB is seated firmly within the base, the switch lever will
be pressed against a special break-away base segment that is loosely connected to the base (Figure 2). Be sure to fasten the break-away
segment to the wall. If the detector unit is forcibly removed from the wall, this segment will break away from the base, causing the tamper switch
to open.

a drill as a screwdriver.
1. Insert a flat-edged screwdriver into the slot and push
upward to remove cover.
2. Remove screw.
3. Separate base from cover.
4. Secure the base to the mounting surface using only the
screws supplied in the package.
CAUTION! Do not remove the PCB to mark holes. Use
one of the following: a slim pencil, nails or the attached
paper model.
CAUTION! Do not use double-sided tape, as this will
tend to insulate the detector from vibrations.

B. Moving part
Note: 868 MHz device is illustrated in the example. The
same mounting procedure should be performed for 433
MHz and 915 MHz devices.
* This additional screw is used for back tamper only.
2.2 Auxiliary Input Wiring (Fig. 4)
A. Connect the auxiliary sensor contacts across the SD-304C PG2 auxiliary input
terminals.
Note: Maximal guaranteed cable length is 10m.
B. If the auxiliary input of the SD-304C PG2 is defined as a Normally Closed (N.C.) type,
series connected N.C. sensor contacts must be used exclusively. An alarm message is
transmitted once the loop is opened.
C. If the auxiliary input of the SD-304C PG2 is defined as a Normally Open (N.O.) type,
parallel connected N.O. sensor contacts must be used exclusively. An alarm message
is transmitted once the loop is closed.
D. For End of Line (EOL) supervision:
Normally Closed (N.C.) or Normally Open (N.O.) sensor contacts can be used, as
shown in Figure 4. A 2.2k E.O.L. resistor must be wired at the far end of the zone
loop. An alarm message is transmitted once the loop is opened or short circuited.
E. For Double End of Line (DEOL) supervision:
Two Normally Closed (N.C.) sensor contacts can be used, as shown in Figure 4. Two
2.2k E.O.L. resistors must be wired at the far end of the zone loop which is opened
or short circuited. Events messages are transmitted according to connected inputs, for
example, Alarm or Tamper contacts.

Notes:
1. If the shock detector is already enrolled, you can configure the device parameters and assign partitions via the “Modify Devices” option – see
Step 2.
2. PARTITIONS will appear only if PARTITIONING was previously enabled in the panel.
2.4 Configuring the Magnetic Contact Device Parameters
Enter the Device Settings menu and follow the configuration instructions for the SD-304C PG2 shock detector as described in the following table.
Configuration Instructions
Determine whether or not the alarm LED indication will be activated.
Optional settings: ON (default) or OFF.
Determine whether to enable or disable the internal reed switch.
Optional settings: Enabled or Disabled (default).
Define whether to enable or disable the detection of magnetic tampering.
Notes:
1. The selected option of this menu is functional only if the Reed Swtich menu was previously set to "Enabled".
2. Supported only by specific control panels.
Optional settings: Enabled or Disabled (default).
Define the external input according to the installer's requirements.
Optional settings: Disabled (default), End of Line, Normally open, Normally close or Double EOL.
Define the sensitivity threshold of the shock detector when configuring from the panel.
Optional settings: Sens. Thresh. 1 to Sens. Thresh. 19 (default setting is Sens. Thresh. 8).
Note: Configuration of this feature can be performed either from the panel or from the device on condition that the
device was already enrolled and there is synchronization between the panel and device. If an “E” appears on the
device’s digital display, this indicates no synchronization.
Define whether Accumulation mode, when configuring from the panel, is Enabled or Disabled.
Optional settings: Enabled or Disabled (default).
2.5 Local Operating and Calibrating of the Shock Detector
The SD-304C PG2 can be calibrated locally only when the device is in Local Diagnostics mode (first 15 minutes after opening the cover). When
the device is not in this mode, but further calibration is required, the installer should reset the device by closing the tamper switch.
1. Press on the "Up" or "Down" button to turn on the digital display. The letter 'G' appears on the display for 3 seconds to indicate Gross Attack
levels (thresholds). Then, the menu appears on the display to enable you to select a number in the range of 1-19. If, instead of a number the
letter "E" appears on the display, this indicates that there is no communication link between the unit and control panel and, therefore, local
adjustment is not allowed.
Note: If no buttons are pressed within 20 seconds, the digital display turns off.
2. Change the threshold by pressing the "Up" or "Down" button.
Note: The lower the threshold, the higher the sensitivity, therefore, the lowest thresholds are more suitable for harder materials, such as
concrete.
3. While the SD-304C PG2 threshold menu is active, knock on the surface with the required force for the detector to set the required threshold.
The power of the detected knock will be presented on the display of the SD-304C PG2 as a blinking number for 3 seconds. The displayed
number will be in the range of 1 to 19, where 1 is very weak and 19 is very strong.
Note: If the installer knocks on the surface but nothing appears on the display, this indicates that no shock is detected. If a hyphen blinks, this
indicates that the knock is above the highest threshold of the detector.
4. Repeat the same test several times.
5. Press the "Up" or "Down" button to navigate to the threshold number to be set and then press the "Up" and "Down" buttons simultaneously to
set the threshold.
6. The detector now moves to the next menu, the Accumulated menu (shown as "A" on the display). Press the "Up" or "Down" buttons to Enable
("1" on the display) or Disable ("0" on the display) the Accumulation mode. Press the "Up" or "Down" buttons simultaneously to set the
selected option.
Note: When Accumulation is enabled, the power of impact will still indicate the strength of a single knock, therefore, it is recommended to
disable this parameter while the Threshold is tested and to enable the Accumulation mode only after setting the Threshold.
7. If after the "Up" and "Down" buttons are simultaneously pressed the letter “E” appears, this likely indicates that there is no communication link
between the unit and control panel. Check if the panel is properly powered.

3. LOCAL DIAGNOSTICS TEST
Before testing, separate the base from the cover (see Figure 3).
A. Press the tamper switch once and release it.
B. Put back the cover to return the tamper switch to its normal (undisturbed) position, and then secure the front cover to the base with the case
closure screw.
C. Use a hammer to apply shock in close proximity to the detector and verify the red LED blinks, indicating detection.
D. After 2 seconds the LED blinks 3 times.
The following table indicates received signal strength indication.
IMPORTANT! Reliable reception must be assured. Therefore, "poor" signal strength is not acceptable. If you receive a "poor" signal from the
device, re-locate it and re-test until a "good" or "strong" signal strength is received.
Note: For detailed Diagnostics Test instructions, refer to the control panel Installer Guide.
