Overview Of System Operation - Sentex SPECTRUM Series Programming Instructions Manual

1 - OVERVIEW OF SYSTEM OPERATION

Your Spectrum telephone entry system stores, recalls, and dials the telephone numbers of your building's
residents/occupants (hereinafter referred to as resident or residents), and responds to signals from their
phones to unlock a door or activate an automatic gate operator. When a visitor arrives at the controlled
entrance, he/she lifts the receiver (if you have a model with a handset), pushes the "#" button on the keypad to
activate the system, and then dials the code that is listed next to the resident's name on the directory. The
resident can then initiate one of four actions by pressing a key on their telephone. These actions are as
follows:
KEY PRESSED
9
5
#
∗
When you dial a "9" or a "5", the controlled entrance unlocks, the display exhibits an "open" indication, and
the system emits a 3-second tone. When allowing entry, neither party should hang up until the display and
tone are activated. It is important that all residents know how the system operates.
The system also has a feature that allows it to be used with codes that, when entered on the system's
keypad, can latch, cycle, or release either of the system's relays. These 4-digit entry codes can be given to
(or chosen by) each resident as well as 10 vendors, service people, etc. Conversely, you can decide to limit
the use of this feature to a few people. An authorized person who wishes to enter the building by this means
presses the "∗" key and their 4-digit code. If a valid code is entered, the controlled entrance will unlock or
activate in the manner described in the paragraph above. If invalid codes are entered successively (the
number of incorrect successive entries allowed can be set between 1 and 9) within a 3-minute period, this
feature will disable itself for 3-minutes while the remainder of the system's capabilities will continue to operate
normally.
For your convenience, a programming guide label has been placed on the inside of the system's cabinet.
This guide is an easy, handy reference for you once you become familiar with the programming procedures.
