Gemini 952N - User Manual

The provided document is a user and installer manual for the Gemini 952N alarm system, designed and manufactured in Italy for 2-wheeled vehicles. It is supplied with two remote controls and does not use a backup battery. The alarm system is factory programmed, but its features can be customized, and the tilt/shock sensor sensitivity can be adjusted.

Function Description

The Gemini 952N is a vehicle alarm system primarily designed to deter theft and signal irregularities. It offers various protection features and can be controlled via remote controls or an emergency PIN code override.

Core Functions:

Arming/Disarming: The system can be armed and disarmed using remote control button "1." Arming is confirmed by acoustic and optical signals (2 beeps, 1 turn indicator flash, steady LED). Disarming is confirmed by 3 beeps and 3 turn indicator flashes.
Immobilizer: The engine immobilizer is enabled during the arming delay and remains active when the system is armed.
Alarm Events: The system detects ignition attempts, tilt/shock, and seat/topcase tampering (if a contact switch is installed). A panic alarm can also be triggered manually.
Audible Alarm Limitation: To comply with noise regulations and save battery life, audible alarms are limited to 7 consecutive cycles for events like unauthorized motion, tampering, or ignition attempts. After 7 cycles, the siren is automatically excluded.
Neutral Time: After an alarm cycle, further alarm events are ignored for 5 seconds, during which the system can be disarmed via PIN code.
Alarm Memory: If an alarm event occurs while away from the vehicle, it is signaled upon disarming by 2 turn indicator flashes and 2 bops. The last cause of the alarm can be identified by counting LED flashes.

Programmable Features (Factory Presets):

Acoustic Signals: Enabled by default, providing audible feedback for operations like arming/disarming. Can be excluded.
Panic Alarm: Enabled by default. Can be triggered by pressing remote control button "2" for approximately 30 seconds, even when the system is armed or disarmed.
Tilt Sensor: Enabled by default. Triggers an alarm upon motion detection. Can be temporarily excluded for a single arming cycle.
Passive Arming: Disabled by default. If enabled, the system automatically arms 35 seconds after ignition is turned OFF.
Anti-hijack Feature: Disabled by default. If enabled, it can be activated while the engine is running via remote control buttons "1" or "2," or an optional anti-hijack button. It triggers the siren and immobilizes the engine after 20 seconds.
Pre-alarm Mode: Disabled by default. If enabled, the siren will sound for 2.5 seconds for the first 3 alarm cycles (e.g., tilt), then for 30 seconds from the 4th cycle onward.
Self-rearming (Anti-distraction): Disabled by default. If enabled, the system automatically re-arms 35 seconds after being accidentally disarmed.

Energy Saver Feature (Sleep Mode):

Disarmed State: The system enters sleep mode 72 hours after being disarmed or engine turned OFF. Remote controls are inoperative, but normal operation is restored by turning ignition ON. Can be manually activated earlier.
Armed State: The system enters sleep mode 72 hours after being armed. All protection features remain operative, except for the status LED. Remote controls are inoperative, and normal operation is restored when ignition is switched ON. A 5-second delay allows disarming without triggering the siren.

Hazard Warning Flashers: Can be activated when the system is disarmed by cycling the ignition key and pressing remote control button "1." Disabled by turning ignition ON/OFF or arming the system.

PIN Code Override: Allows emergency disarming if remote controls are lost or inoperative. The PIN code is entered using the vehicle's ignition key. The factory default PIN code is 1-1-1-1 and can be customized.

Important Technical Specifications

Power Supply: 12 Vdc
Power Supply Range: 9Vdc-15Vdc
Current Absorption @ 12Vdc (armed, LED flashing): <2mA
Current Absorption in Sleep Mode: <1mA
Siren Sound Level: 118 dBA @ 1 m
Relay Capacity: 8A
Turn Indicator Output: 12V max. (6A max. per side)
Remote Control Frequency: 433.92 Mhz
Batteries (Remote Control): CR1616 (risk of explosion if incorrect type is used)
Sensors: Built-in high-sensitivity triaxial tilt/shock sensor with 4 levels of sensitivity adjustment (factory preset to minimum sensitivity).

Usage Features

Remote Control Operation: Two buttons for various functions (arming/disarming, panic alarm, anti-hijack, siren/tilt sensor exclusion).
Low Battery Indicator: The remote control LED blinks when a button is pressed, signaling low battery charge.
PIN Code Customization: The 4-digit PIN code can be changed from the factory setting.
Learning New Devices: Up to 8 remote controls can be learned by the system. Saving an extra device automatically deletes the first one.
Tilt Sensor Adjustment: The sensitivity of the tilt/shock sensor can be adjusted through 4 levels.
Optical/Acoustic Signals: Operations are signaled both acoustically (beeps, bops) and optically (LED, turn indicators).

Maintenance Features

Remote Control Battery Replacement: Instructions are provided for replacing CR1616 batteries, emphasizing correct polarity and avoiding incorrect battery types.
General Care:
- Do not clean the alarm unit with water; use a damp cloth.
- Do not use voltages other than specified.
- Protect the alarm from direct water flow (e.g., car wash).
Installation Considerations (Installer Manual):
- Alarm Unit Sealing: Proper sealing with a rubber cap and screws is crucial to prevent water ingress.
- Alarm Unit Positioning: Can be positioned vertically or horizontally. Must avoid water ingress points, muffled siren, moving parts, high-frequency electromagnetic disturbances, high temperatures, and direct mounting on the vehicle frame. A "goose-neck" bending of the rubber sheath is recommended.
- Status LED Installation: Must be installed where visible as a deterrent and indicator.
- Contact Switch (Optional): Must detect opening without being accessible from outside and have a carefully set trigger threshold.
- Anti-hijack Button (Optional): Connects to the White-Violet wire and triggers on a negative signal.
- Diode Installation: May be required for turn indicators to prevent instrument panel lights from activating when the alarm is armed.

Warranty Conditions: The product is guaranteed for 24 months from the date of purchase. The warranty is void if labels are missing/torn, the certificate is incomplete, or the sales receipt is missing. The manufacturer is not responsible for installation, after-sales service, or technical support, and declines responsibility for malfunctions or damages caused by improper installation, use, or tampering. The alarm system is solely intended as a theft-deterrent device.
