The single door System 2 (Model 2003) supports 295 users and each user can be added or deleted in seconds using the built-in Programming Keypad. The programmable relay can control almost any device including an electric Door Lock, arm or disarm an Alarm System, shunt an Alarm Device, or operate a Garage Door. Users can access a secured area using Keypads, Card Readers, or Data Chip Readers. A Request-To-Exit button can be used to exit an area and a Magnetic Contact can be installed to report Door Ajar and Forced Entry conditions. For applications requiring time restriction of users and/or automatic relay operation, 8 time schedules with 256 time zones are supported. Users can pass through an entry point secured by a keypad, reader, or combination of both by entering a correct code into the keypad or presenting a valid card or Data Chip to the reader. The System then decides if the user is allowed access to this door at the current time and date, either grants or denies access and logs the transaction. Public access doors can be programmed to automatically lock and unlock according to the programmed time schedules set up by the System Administrator. System 2 has a built-in clock and calendar that automatically adjusts for daylight savings times and leap year. System 2 can be monitored and reports can be printed from an off-site location using dial-up phone modems. The 2003 has two heavy-duty relay and one voltage output. The main relay is usually used to lock and unlock a door and the other relay (auxiliary relay) is available for any other purpose. The auxiliary relay and voltage output can be programmed to activate from any System event such as: System Reset, Door Ajar, Memory Clear, Invalid Code, PIN Error, Forced Entry, etc. System 2 also has an emergency 12VDC input which, when activated, will open the normally closed contacts of the door relay(s). For more detailed information you can view the cutsheet. Each System panel is equipped with two of the following outputs/inputs: Main Relays, Auxiliary Relays, Voltage Outputs, Door Ajar / Forced Entry Inputs, Request-To-Exit Inputs, Zone Inputs and one Emergency Drop Input.
