The Targus DEFCON 1 is the only system that combines a steel cable with motion sensor alarm technology. Pocket size system is easy to carry, simple to use, and difficult for thieves to disarm. Simply set 3-digit combination, loop steel cable through equipment or carrying case, and snap the steel cable back into the DEFCON 1 to activate the alarm system. Siren is activated when cable is severed, or motion sensor is armed and triggered. Motion sensor can be set to either High or Low sensitivity modes and is great added feature especially in situations when there is no anchor to loop steel cable through. Flashing Alarm Light indicates alarm status and helps deter theft. Includes 4.7ft Steel Cable, 110 dB Alarm unit and Lock with 1,000 User-Settable combinations. Operates with 9v battery included. Battery life with continuous use (lock connected with alarm off) is approximately 90 days. Easily attaches to your carrying case, luggage or any computer with a security slot lock.
