Risco ShockTec Plus Grade 3 Installation Instructions

Introduction

ShockTec Plus Grade 3 is a digital shock detector with magnetic 

contact for internal use that provides reliable 24-hour perimeter 

protection. A break-in is detected as soon as the intruder attempts to 

force, smash, drill or even saw through the protected window, door, 

wall or roof. ShockTec employs an advanced digital microprocessor to

analyze the vibration signal received from the piezo electric sensor.

A unique feature of ShockTec Plus Grade 3 is digital sampling of the 

signal simultaneously in two separate channels, each channel 

ampli

fi

ed at a different gain. This provides an extremely wide dynamic 

range of the sampled signal, enabling precise measurement and 

analysis of the shock signal.

The ShockTec Plus Grade 3 has a magnetic reed switch for double 

protection of shock plus opening of windows or doors.  Any attempt to 

defeat the detector by using large magnets, as de

fi

ned by 

EN-50131-2-6 Security Grade 3 requirements, will cause a tamper 

condition.

Main Features

  •  Digital Microprocessor with Intelligent Digital Signal Processing

  •  Tri-color LED enables accurate and reliable calibration, with 

     “over- sensitive” and “under-sensitive” indications

  •  Gross attack detection

  •  Internal magnetic reed switch for double protection 

     (shock and contact)

  •  Detects attempts of magnet tampering (0.3T)

  •  Encapsulated bi-morph piezo electric sensor

  •  Dual stage adjustment potentiometer 

  •  Cover anti-tamper protection

  •  Compatibility with most control panels

Modes of LED Indication

The LED of the ShockTec Plus G3 has three operational modes. The 

NC alarm contacts are non-latching in all modes of operation. On alarm 

activation, the alarm contacts open the circuit for 2.5 seconds.

1. Normal Operational Mode

No voltage is applied to the LED Terminal. The LED illuminates while 

the ALARM contact is open in response to an input signal. 

     •  GREEN: Indicates an alarm condition.

     •  RED: Under -Sensitive indication.

     •  ORANGE: Over-Sensitive indication. 

2. Any to Latch Mode

12V is applied to the LED terminal causing it to be inhibited. Upon 

removal of the 12V, the detector switches to a Normal Operation Mode 

and a continuously 

fl

ashing ORANGE LED indicates if an alarm is 

detected (Alarm memory). Reapplication of 12V resets the latch (Alarm 

memory) and extinguishes the LED.

3. First to Latch Mode

12V is applied to the LED terminal via a 47k resistor (see Figure 2) 

causing it to be inhibited. Operation is the same as in Any to Latch 

Mode with the exception that only the 

fi

rst detector to detect an alarm 

is indicated by a continuous 

fl

ashing Orange LED, whereas any 

subsequent detector is indicated by a steady Orange LED. 

Installation Procedure

1   Select the intended position for installation, ensuring the surface 

     is clean and clear of any irregularities. Refer to Table 1 for 

     details about detection ranges for the different surface types. 

     NOTE:

When installing the Magnetic Contact, refer to the 

                 Considerations for Magnet Installation section.

2   Remove the cover of the detector by unscrewing the lens using 

     the special key supplied and then unscrewing the single captive 

     screw, until the cover is easily removed from the base.

3   Carefully lift the printed circuit board from the base by releasing 

     the restraining catch.

4   Place the base on the mounting position and mark the desired 

fi

xing holes.

5   If rear cable entry is required, thread the cables through the rear 

     of the base by removing the appropriate knockout.

6   Fix the base in position.

7   Carefully clip the printed circuit onto the base.

8   If side cable entry is required, draw the cable through the rubber 

     grommet and complete the electrical connection.

9   Set the detector’s sensitivity as follows:

     NOTE:

The LED terminal should not be connected 

to 12V 

     supply during the sensitivity test.

           i     With the unit set for normal operation, use a suitable 

                 instrument to bang or tap the protected area.

           ii    If the sensitivity needs adjustment, use a screwdriver to 

                 adjust the trimmer (turn the trimmer control clockwise to 

                 increase sensitivity or counter-clockwise to reduce 

                 sensitivity). 

           iii   Repeat steps i and ii until the desired sensitivity level is 

                achieved. If required, you can remove the High/Low 

                Sensitivity jumper on the circuit board to reduce 

                sensitivity range (High sensitivity – jumper shorted, Low 

                sensitivity – jumper removed).

10  Replace the cover of the sensor (including the rubber grommet) 

      and tighten the captive screw.

11  Recheck the detector’s response to the desired impact.

12  Insert and screw the lens into the cover using the special key 

      supplied for this purpose.
