• Changed details for sensitivity settings description and tables inline with PCR01407 10-03-2022 • PCR01350 updated PCB schematics and wiring details to accommodate PCB changes. 18-10-2022 • Impaq S Grade 3 added to the manual.
1.0 Introduction The Impaq S is a Grade 2 wired shock sensor, the Impaq SC is a Grade 2 wired shock sensor with the option for a magnetic contact, and the Impaq S Grade 3 is a Grade 3 shock sensor.
Screw Diameter 2.9-3.2mm Screw length: 15.8-24.5mm Impaq S Grade 3 MUST use the fixing points shown in RED on Fig 3 for the removal from mounting tamper to function correctly. Care should be taken when screwing through the PCB for the rear tamper breakout.
2.2 Magnet mounting (type SC only) Once the device has been mounted, position the magnet so the notch is aligned with the arrow marker on the PCB. The magnet can be installed on either side of the device. Greater sensitivity is achieved by positioning the magnet so the notch is aligned with the arrow (see figure 4 for magnet distances).

The Impaq S and S Grade 3 have three wiring options. In all cases, power should be provided to the 0V and 12V by an EN50131 compliant power supply. Option 1 The alarm and tamper loops can be wired independently and function as normally closed zone inputs.
Page 18
Note: the EOL DIP switches should all be turned OFF in this configuration Option 3 The third way of wiring an Impaq S is to use the EOL DIP switch selected resistors for alarm and tamper. In this configuration. The zone wires should then be connected to the outer alarm and tamper terminals.

NOTE: The product will only function if both DIP switches have a single switch set to the ON position. If multiple switches are moved, the product will not function as expected. Optional wiring There is a facility to remotely enable the walk test LED from the panel. To use this connect a wire from the RLED terminal to an output of the panel.

NOTE: The product will only function if both DIP switches have a single switch set to the ON position. If no switches or multiple switches are moved, the product will not function as expected. Optional wiring There is a facility to remotely enable the walk test LED from the panel. To use this, connect a wire from the RLED terminal to an output of the panel.
6.0 Setting the shock sensitivity After powering up the device, single press the sensitivity button and the LED will flash blue defaulting to sensitivity setting 2. There are 5 sensitivity settings from 1 to 5 with 1 being the least sensitive (slowest flash rate) and 5 the most sensitive.
Note: To be used with PSU’s that have a current limit of 5A or below. Note: Product is designed for indoor use only.

Maintenance: Test yearly by the installer. Warranty: 2 year replacement warranty. As the Impaq S/SC and Impaq S Grade 3 is not a complete alarm system, but only a part thereof, Texecom cannot accept responsibility or liability for any damages whatsoever based on a claim that the Impaq S/SC and Impaq S Grade 3 failed to function correctly.
