Key Features of Home Security System with LCD and Keypad

• Monitors between one and eight entry/exit points [zones] of a building or room
• Unique 40 years EEPROM memory circuitry for a complete peace of mind
• Allows monitoring to be totally or partially suspended when required by the legitimate guardians [users] of the premises
• Indicates audibly [e.g. bell] and/or visibly [e.g. strobe/flasher] when one or more zones have been entered without authority
• Turns off activated bell after a preset period to prevent annoyance to neighbors
• Allows timed zone entry/exit [time-out] for users without triggering the full alarm
• Allows full monitoring of required zones once time-out has ended
• Allows users to terminate time-out procedure
• Allows users to control the monitoring system by means of a unique alphanumeric personal identity code [PIN] entered via a keypad
• Allows users to change the PIN code
• Normally powered from a mains power source
• Instantaneously switches over to being powered by a heavy duty back-up battery if mains power fails
• Keeps the battery fully charged when mains power is present [the battery should be capable of keeping the monitoring system and any activated alarms operational for a reasonable period]
• Allows the system to resume active monitoring should power totally fail but subsequently resume
• Indicates that there has been a total power failure even after power has been resumed
• Prevents the bell from being activated when power is resumed
• Indicates for later viewing whether zones have been entered, even though there may also have been a power failure and resumption
• Allows monitoring of fewer zones than are available
• Automatically recognizes whether a sensor should be monitored for an open circuit or a closed circuit
• Allows open circuit or closed circuit sensors to be used without system modification
• Recognizes that a sensor is incorrectly open or closed prior to monitoring being activated and indicates which sensor is incorrect [i.e. door open when it should be closed]
• Allows users to preview zone sensor status
• Allows the bell-on time to be set for a shorter period than the 40 minutes
• Allows users to check the system by means of indicator lights without activating the bell [etc.]
• Allows indicator lights to display the status of the power supply and bell [etc.]
• Provides anti-tamper warning of interference with the system
• Provides a "Panic" button that immediately activates the bell [etc.] even if the system is not set for full zone monitoring
• Provides "passive" advice [e.g. buzzer] that a zone has been entered even if the system is not set for full monitoring, and for the advice to be terminated once the zone has been vacated [e.g. to monitor shop-door opening/closing]
• Accepts all conventional types of switched-output commercial sensor, including magnetic catches, pressure pads, passive infrared [PIR] devices, vibration detectors, etc., and for any mixture of these to be used
• Inherently stable and most unlikely to be triggered except via the installed sensors
