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.
Sections 1.1 and 1.2 and 1.3 show the key parts of the devices.

2.0 Mounting
2.1 Device mounting
Select the intended mounting position. The device can be installed in any
mounting orientation.
Open the device cover and remove the PCB using a screwdriver (see figure 1)
Remove the cable knockouts (see figure 2)
To ensure product compliance with EN50131, fix the base onto the
mounting surface (see figure 3) using the following screw type:
Head Type: Counter Sunk flat head
Head Diameter: 5.3-6.8mm
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. Overtightening the screw could cause the PCB tracks
to break and leave the device permanently in tamper. This is not
reversible and the PCB will need to be replaced.
NOTE 1: If the product is mounted on concrete, suitable wall plugs should be used.
NOTE 2: If installing the Impaq SC the same screw types should be used to mount

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).

3.0 Impaq S and S Grade 3 wiring

INS877-4 17/26
configuration
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.
Note: that the EOL DIP switches should all be turned OFF in this configuration

INS877-4 18/26
Option 2
The Impaq S can also be wired with leaded resistors in an EOL configuration. The
alarm resistor should be connected across the alarm terminals, and the tamper
resistor should be connected from the right-hand alarm terminal to the left-hand
tamper terminal.
The zone wires should be connected to the outer alarm and tamper terminals.
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.
The EOL DIP switches should be set to the required zone EOL configuration.

INS877-4 19/26
Select the correct resistance value for Tamper and Alarm by moving the DIP switch
to the ON position (Texecom values shown in example below).
EOL DIP Switch Position Tamper Alarm Manufacturer
1 2K2 4K7 Texecom
2 1K0 1K0 Honeywell
3 4K7 6K8 Scantronic/Menvier
4 5K6 5K6 DSC

INS877-4 20/26
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: This overrides the LED DIP Switch settings.
4.0 Impaq SC wiring configuration
The Impaq SC has only one wiring option
The Impaq SC’s only wiring option is EOL via DIP switches. The zone wires should
be connected to the EOL terminals, and the required EOL resistor options should
be chosen on the EOL DIP switches.
Connect two cores into the terminals marked MAG for the alarm signals from the
magnetic contact.
Note: The shock and contact functions must be wired as two separate zones in the
panel.
