Hinge

The 5402 and 5422 shock sensors respond to the shock waves
of sheet metal that is being cut, sawed, impacted, or drilled. This
quality makes it ideal for protecting sheet metal enclosures such
as control panels, alarm housings, electrical panels, and telephone
junction boxes. No sensitivity adjustments make installation quick
and easy.

The 5402 is a lithium battery powered, two-wire sensor. The 5422
is a 4-wire externally powered sensor operating from a
9-24 VDC supply. Both have closed loop outputs.

Sensor Operation

When the sensor is operational and detects an attack, the sensor
alarms, producing three responses:

1. The red LED on the sensor goes on for the period of time the
alarm loop is open (2-6 seconds).

2. The loop impedance of the sensor changes from <15 ohms
(closed) to >1.0 megaohms (open).

3. This is registered by the alarm panel as an alarm. After an
alarm, the sensor automatically resets itself, while the LED
extinguishes simultaneously.

STEP 1 - MOUNTING

Sheet metal enclosures to be protected shall not exceed 2 x 4 x 1 ft.
(61 x 122 x 30.5 cm), and shall have a maximum wall thickness of

0.135 inches (0.343 cm). The enclosure must be solid sheet
metal, have all sides connected (welded, bolted, etc.), and the lid
attached by hinges or screws.

Locate the sensor inside the enclosure on the side wall on or
near the hinge. If the hinge runs the length of the side, center the
sensor vertically. If the enclosure has multiple hinges, place the
sensor next to the hinge nearest the middle of the enclosure (see
Figure 1).

Mounting the Sensor

1. Clean the area where the sensor will be mounted with a 50/50
solution of isopropyl alcohol and water on a clean cloth.

2. Dry the area.

3. Peel the backing from one side of the tape pad. Center the
tape pad on the back of the sensor. The tape pad must be
flat against the plastic case.

4. Remove the remaining backing paper from the tape pad.
Place the sensor against the metal and press firmly.

NOTE: Although the 5402 and 5422 have inherent false alarm
immunity, a few simple precautions must be observed to prevent
false detections.

1. Mount the enclosure and lid securely so that they do not
rattle. Use foam pads to eliminate lid rattle.

2. The enclosure should be clear of vibrating objects (i.e.,
bells, machinery, motors, etc.).

STEP 2 - WIRING

Remove the cover by depressing the snap in the slot at the end of
the sensor and lifting the cover. Connect wires to the terminal
block as labeled on the circuit board (see Figure 2).

Run the wires out the terminal block end of the plastic base. Notch
out center wire exit in the cover and snap in place.

STEP 3 - TESTING

To verify sensor operation, lightly scrape the metal shaft of a
screwdriver (8" or larger) back and forth against the metal edge of
the enclosure (see Figure 3). The LED should light. Do not use the
side with sensor to test as it will be most sensitive. If the sensor
range is not sufficient, add another sensor (see Figure 4).
