The Hornet 740T
is a 3-channel car alarm/security system manufactured by Directed Electronics, Inc. (DEI), the parent company of brands like Viper and Python. It offers basic security and convenience features using older technology like Code-Hopping.
Key Features and Specifications
Security: Features a dual-stage Stinger® DoubleGuard® Shock Sensor (detects light impacts for a "warn-away" chirp response and heavy impacts for a full alarm trigger) and Failsafe® Starter Kill to prevent the engine from starting when armed.
Siren: Equipped with a Revenger® Six-Tone Siren that sounds for 30 seconds during a triggered sequence.
Remote Controls: The system originally included two 3-button remote transmitters using Clone-Safe® Code-Hopping® technology to prevent unauthorized remote duplication.
Convenience: Offers keyless entry, Dome Light Supervision (turns on the interior light when disarmed), and two auxiliary outputs for additional functions like trunk release.
Status Indicator: Includes a bright blue LED status indicator light to show the system's current armed/disarmed/valet status.
Nuisance Protection Circuitry (NPC): A feature that temporarily bypasses a faulty sensor input if it triggers the alarm three times within an hour to prevent continuous false alarms.
Valet Mode: A mode that allows the vehicle to be serviced or operated normally without engaging the alarm system, typically activated using a hidden push-button valet switch.
