Do you have a question about the Gemini 7590T and is the answer not in the manual?

Overview

The Gemini 7590T (Art. Code 7590TK15) is a Thatcham Cat 1 approved vehicle alarm system with dual-point immobilization and built-in sensors, designed for use in vehicles with a negatively grounded 12V battery. This manual provides installation and use instructions.

Function Description

The 7590T offers comprehensive security features, including:

  • Arming/Disarming: Via random rolling code transmitters or an electronic key.
  • Engine Immobilization: Double engine immobilizer, activated passively.
  • Visual and Acoustic Signals: Blinker, siren (intermittent or continuous, programmable), and alarm memory (optical/acoustic signals).
  • Protection Zones: Perimeter protection, volumetric protection (ultrasonic or hyperfrequency module, excludable during arming), and current absorption sensor (programmable).
  • Comfort Features: Control for Central Door Locking (CDL), power windows, and sunroof (for vehicles with Comfort Pack).
  • Special Functions: PANIC or BOOT RELEASE (programmable), anti-distraction rearming (programmable), and output for self-powered or additional sirens.

Important Technical Specifications

  • Nominal Tension: 12 Vdc
  • Nominal Supply Voltage Range: 9-15 Vdc
  • Current Absorption @ 12Vdc: < 2mA with system armed and LED flashing
  • Turn Indicators Contact Capacity: 10A at 20°C
  • Engine Block Contact Rating: 8A
  • Alarm Triggering: 30 sec.
  • Max Positive Current with System Armed (+A): 700 mA
  • Siren Output Current Capacity: 3A

The remote control operates at 433.92 MHz.

Usage Features

Arming the Alarm: Press remote control button 1 or touch the electronic key to its receptacle. A quick flash of the turn indicators confirms arming. Functions enabled include module output, LED output, engine immobilizer, and door-lock control. If the electronic key is used, an entry delay (approx. 10 sec., LED ON steady) allows entry to disable the alarm without triggering it.

Arming Delay, Sensor and Comfort Exclusion, Window-Up Stop: An arming delay of approximately 45 seconds (LED ON steady) provides exit time. During the initial 25 seconds, external sensors can be excluded and window roll-up stopped by pressing button 2 on the remote control (requires module 2344 or Comfort System). A quick flash of turn indicators confirms exclusion. Sensor exclusion is valid for a single alarm activation cycle.

Siren Sound Exclusion When Arming: To arm silently, turn ignition key "ON", wait for the LED to turn ON (approx. 0.5 sec.), then press remote control button 2 while the LED is ON. The LED will turn OFF. To reactivate acoustic signaling, arm and disarm the system. Siren sound exclusion is valid for each single arming cycle.

Total Arming After Arming Delay: After the 45-second delay, the system is fully armed. The LED flashes (200ms ON, 2sec OFF) to minimize power consumption.

Alarm Conditions: The system detects various alarm conditions: wire tamper (via self-powered siren), ignition attempt, power drain (if enabled), door tamper, boot tamper, bonnet tamper, motion detection by internal ultrasound volumetric sensor, motion detection by external sensors (optional, wireless), and panic alarm (programmable via button 2). Ignition and door/boot switch inputs have a 200ms debounce time to filter noise. An alarm event triggers acoustic signals (if enabled) and turn indicator flashes for 30 seconds, with the LED ON steady. Each input can trigger up to 5 alarm cycles per arming cycle, each lasting 30 seconds. Ignition attempts and wire tamper alarms have no limitations.

Alarm Cycle: Turn indicators and siren activate for 30 seconds. Additional siren provides a continuous audible signal, while the original horn provides an intermittent sound (2" ON - 2" OFF). The LED is ON steady. Pressing button 2 can interrupt the cycle without disarming. Each input triggers the alarm 5 times per activation cycle to limit acoustic pollution.

Neutral Time Between Alarm Cycles: After an alarm, there's a 5-second interval before another alarm cycle can start, during which no reaction to alarm events occurs. The LED is ON steady, then resumes normal flashing.

Alarm Disarming: Press remote control button 1 or touch the electronic key. Three flashes of turn indicators confirm disarming. If an alarm occurred while armed, 5 flashes signal this.

Alarm Memory: Five flashes of turn indicators when ignition is turned ON indicate a past alarm event. The last cause is identified by observing the status LED and counting flashes. This sequence repeats 5 times; turn ignition key "OFF" to interrupt.

Programmable Functions: The alarm system is factory configured but allows modification. To enter configuration mode: disarm the alarm, open and leave open the driver door, turn ignition key "ON". The status LED turns ON for 0.5 seconds; while ON, simultaneously press both remote control buttons. Turn indicators and LED flash twice to confirm entry into configuration mode. To enable a function, press button 1 (LED flashes once); to disable, press button 2 (LED flashes twice). Each button press moves to the next function. Turning ignition key "OFF" exits the procedure.

  • Acoustic Signals (8.1): Permanently exclude all acoustic signals.
  • Panic Alarm or Boot Release (8.2): If enabled, button 2 activates optical/acoustic alarm signals for approx. 30 seconds (can be silenced by pressing button 2 again). If disabled, button 2 activates BOOT RELEASE. If the boot is released while armed, there's a 60-second delay for loading/unloading without triggering an alarm.
  • Current Absorption Sensor (8.3): Activates the alarm if a voltage change occurs in the vehicle electrical circuit (e.g., lamp switching on).
  • Anti-Distraction Rearming and Auto-Lock (8.4): Prevents the vehicle from being left unprotected if accidentally disarmed. The system rearms if no other activity is detected within 35 seconds. The CDL control is activated, requiring the driver door switch to be connected to the GREEN/BROWN alarm wire. Doors automatically lock 20 seconds after ignition is turned ON and unlock when ignition key is turned OFF.
  • Passive Arming (8.5): Engine block passive arming automatically activates double ENGINE LOCK 60 seconds after the engine is switched OFF or 60 seconds after the alarm is disabled. The status LED flashes quickly. If a door is opened, the countdown stops and restarts when the door is closed.
  • Lock Time (8.6): Factory preset at 0.5 seconds, adjustable to 6 seconds. Setting to 6 seconds causes windows to open when disarmed if comfort function is enabled.
  • Comfort Control (8.7): Automatically closes all windows when the alarm is armed. The power window motor receives a 25-second command to roll-up windows.
  • CDL Double Pulse Unlock (8.8): If enabled, provides a double pulse unlock (approx. 0.5 seconds each) upon disarming. The first pulse unlocks the driver door, the second unlocks remaining doors. Only active if lock/unlock time is 0.5 seconds; 6 seconds automatically disables this function.

Ultrasonic Volumetric Sensor Adjustment (9.0): Provides interior protection. To adjust sensitivity: arm the system excluding sensors, adjust the trimmer to a medium setting. After arming delay, introduce an object in the cabin and move it; the status LED turns ON to signal presence. Readjust trimmer if sensitivity is too high or low.

Learning New Control Devices (10.0): Memory stores up to 8 devices (remote controls, electronic keys, magnetic contacts). If an extra device is added, the LED flashes quickly to indicate full memory.

  1. Disarm alarm, open driver door and bonnet.
  2. Turn ignition key ON.
  3. Press a button on an already learned remote or insert an electronic key.
  4. Two slow flashes of turn indicators confirm learn mode.
  5. For new device: press button 1 on remote, insert electronic key, or make magnetic contact transmit.
  6. Status LED flashes once to confirm learning.
  7. Repeat for other devices.
  8. Turn ignition key OFF.
  9. A long flash of turn indicators confirms end of procedure. Note: Do not close the bonnet during step 1, or all previously programmed devices will be erased.

Maintenance Features

Remote Control Battery Replacement: The remote control has a low charge battery indicator (LED blinks when a button is pressed). Use only CR 1616 batteries.

  1. Separate remote halves carefully.
  2. Remove discharged batteries and insert new ones, ensuring correct polarity.
  3. Close remote halves and verify functionality.
