4.2.3 Inputs 1 to 5
Inputs 1 to 5 are situated at the bottom of the main controller board and are
assigned specific functions. Inputs 1 to 3 have pre-defined functions and connect
to specific devices. Inputs 4 and 5 are general purpose inputs that can be
correlated to activate a general purpose output.
Inputs 1 to 5 are designated as follows (see figure 29):
Input 1. Postal Lock. Input 1 connects to the Postal Lock. Activation of this
input unlocks the main door and starts the main door timer. The door locks when
the timer expires or when the door sense input is activated. Daily usage is set as
unlimited or limited. When set as limited daily usage is set according to a pre-
defined number. Any attempt to use the postal lock beyond a set daily limit
causes a warning message to appear and the system to return to normal operation.
Input 1 also, when configured, activates a general purpose output to perform any
required function.
Input 2. Fire Panel. Input 2 connects to the fire alarm panel and receives fire
notification. Activation of this input unlocks the main and auxiliary doors. These
outputs are active as long as the fire panel input is active. Input 2 also, when
configured, activates a general purpose output to perform any required function.
Input 3. Main Door Sense. Input 3 connects to the door sense switch. Unlocking
the main door activates the main door open timer. Activation of the Main Door
Sense locks the main door and resets the main door open timer. This function is
typically used to prevent 'tailgating'. Input 3 also, when configured, activates a
general purpose output to perform any required function.
Input 4. General Purpose. Input 4 is a general purpose input that, when
configured, activates a general purpose output to perform any required function.
An example of a typical application is the use of an optional tamper switch
(see figure 31).
Input 5. General Purpose. Input 5 is a general purpose input that, when
configured, activates a general purpose output to perform any required function.
