Your vehicle is now secured with the Scorpion S50 / S50L alarm. Please read the following instructions carefully and familiarise yourself with the alarm system’s features and operating procedures.

System Description

This alarm system protects your vehicle by means of the following security features:

  • Built-in triaxial tilt/motion sensor — When the system is armed, the motion sensor triggers an alarm whenever it detects that the vehicle is being moved or lifted.
  • Negative trigger switch (optional) — A switch installed to protect the vehicle doors (negative trigger input). Opening the vehicle doors will trigger the alarm.
  • Wireless sensors (optional) — Window opening detector, door magnetic contact, volumetric or PIR detectors.

Remote Controls

The alarm is supplied with two 4-button remote controls (SIG848).

The SIG848 remote control has a low battery charge indicator that gives you early warning to avoid malfunctioning. When the batteries are fully charged, the indicator LED will show a steady light at the press of a button. If the batteries are low, the LED will start blinking rapidly when the button is pressed.

Arming & Disarming

System Arming

The alarm unit can be armed by pressing the arming button on either remote control. Two high-pitched beeps will confirm the operation and the dome light will turn on for approximately 30 seconds. The system has a 30-second arming delay which allows you to exit the vehicle without triggering an alarm. After the arming delay, the system is fully armed.

System Disarming

To disarm the system, press the disarming button on either remote control. Three high-pitched beeps will confirm disarming and the dome light will turn on for approximately 30 seconds.

Arming Without Sensors

The system can be armed without enabling the wireless volumetric sensors. To do so, press button 3 on either remote control to arm the system. One high-pitched beep will confirm the system is armed with the sensors excluded.

Please note: sensor exclusion is bound to a single arming cycle. Sensors will automatically be enabled the next time the alarm is armed.

Tilt Sensor

Tilt Sensor Exclusion

To temporarily exclude the tilt sensor, proceed as follows:

  1. Arm the alarm system by pressing remote control button 1 (full arming) or button 3 (partial arming: armed with volumetric sensors override).
  2. Within 4 seconds, press button 3: tilt sensor exclusion will be confirmed by 1 beep.

Note: the tilt sensor will remain excluded for the one arming cycle; it will be automatically restored at the next arming.

Tilt Sensor Adjustment

The tilt sensor sensitivity level is factory set to trigger an alarm if the vehicle is tilted at an angle of approximately 3.5° with respect to the X, Y and Z axes. Sensitivity can be custom adjusted as follows:

  1. Disarm the alarm system.
  2. Simultaneously press (twice in a row) remote control buttons 1 and 2: 2 beeps will confirm the system is in ‘Adjustment Mode’ (every time you enter Adjustment Mode, the sensitivity level is automatically restored to the 3.5° default).
  3. Press button 2 once to increase the tilt angle to 7°: confirmed by 1 beep.
  4. Press button 2 again to increase the tilt angle to 10.5°: confirmed by 1 beep.
  5. Press button 2 once more to increase the tilt angle to 14°: confirmed by 1 beep.

To exit the adjustment procedure and confirm the selected tilt angle, simultaneously press remote control buttons 1 and 2 after performing the steps above. The system will automatically exit Adjustment Mode after step 5; 1 beep will confirm the end of the procedure.

Dome Light

Arming or disarming the alarm unit will activate the dome light output for up to 30 seconds. This function can be used to turn on a lamp to illuminate the vehicle access door. The 4-button remote control can be used to turn the lamp on or off. The light will turn off automatically after a time-out of 5 minutes.

Alarms & Trigger Memory

Alarms

Alarm events will sound for a maximum of 30 seconds. If the alarm remains, or if it is not cleared, it will trigger another alarm cycle after a 5-second delay (trigger interval). Each alarm condition will trigger a maximum of 8 alarm cycles. The duration and time of occurrence of alarms comply with the Environmental Protection (Noise) Regulations. After each cycle there is a rest time of 5 seconds before the system is fully operative again.

Alarm Trigger Memory

If there has been an alarm trigger during your absence, it will be signalled by 5 beeps upon disarming. The last cause of alarm can be identified by the number of siren chirps:

  • Wireless magnetic contacts or opening detectors — 1 chirp
  • Wireless infrared (PIR) or hyper-frequency sensors — 2 chirps
  • Negative input alarm — 3 chirps
  • Triaxial tilt sensor — 4 chirps

Pairing New Devices

The alarm is supplied with 2 remote controls, but extra optional devices can be added. Pairing new remote controls or wireless sensors is done via the LEARN button provided on the alarm harness.

Please note: the alarm memory will store 12 devices; saving an extra device will automatically delete the first one.

  1. Press the LEARN button 5 times in a row within 5 seconds. Each button press generates 1 beep, and 2 final beeps confirm the system is in LEARN mode.
  2. Press one of the remote control buttons, or activate the sensor to be learned, within 30 seconds: otherwise the system will automatically exit the learning procedure.
  3. A siren chirp will confirm the new device has been learned.
  4. To exit learn mode, press the LEARN button once.

Battery Replacement

When the remote-control batteries are too weak, replace them as follows:

  1. Separate the remote control halves, taking care not to damage the internal circuit.
  2. Remove the discharged batteries and insert the new ones, taking care not to invert the battery polarity.
  3. Close the remote halves and make sure the remote works properly by pressing any button: the LED indicator should turn on.

Please note: battery type, CR2032. Different battery types can seriously damage the remote control. Discard used batteries properly in dedicated containers.

Frequently Asked Questions

How do I arm the alarm without the interior (volumetric) sensors?

Press button 3 on either remote control to arm. One high-pitched beep confirms the system is armed with the sensors excluded. Note that sensor exclusion lasts for a single arming cycle: the sensors are automatically re-enabled the next time you arm.

The tilt sensor keeps triggering, can I reduce its sensitivity?

Yes. The tilt sensor is factory set to about 3.5°. Disarm, then press remote buttons 1 and 2 together to enter Adjustment Mode, and press button 2 to step the angle up to 7°, 10.5° or 14°. Press buttons 1 and 2 together again to confirm.

What do 5 beeps on disarming mean?

Five beeps signal that an alarm was triggered while you were away. You can then identify the cause from the number of siren chirps: 1 = magnetic contacts/opening detectors, 2 = PIR/hyper-frequency sensors, 3 = negative input alarm, 4 = triaxial tilt sensor.

Which batteries do the remote controls use?

The SIG848 remote controls use CR2032 batteries. Do not substitute a different type, as it can seriously damage the remote control.

How many devices can the alarm store?

The alarm memory stores up to 12 devices. Adding a 13th device automatically deletes the first one that was paired.
