Alarm Circuit
- A Transistor Based of Single Zone Alarm - If the building is not secure, when you switch the alarm on the buzzer will sound.
- Hijack Alarm - This circuit is designed primarily for the situation where a hijacker forces the driver from the vehicle. If a door is opened while the ignition is switched on, the circuit will trip.
- Car Alarm and Immobilizer - This circuit features exit and entry delays, an instant alarm zone, an intermittent siren output and automatic reset.
- Single Zone CMOS Alarm - This circuit has provision for normally open and normally closed switches and will accommodate the usual input devices such as Foil Tape, Pressure Mats, Magnetic Reed Contacts, Passive Infrared Detectors and Inertia (Shock) Sensors.
