Figure 14.Tamper Switch - Mircom TX3 Series Installation And Operation Manual

Inputs 1 to 5 are designated as follows (see Figure 13):
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 14).
Input 5. General Purpose. Input 5 is a general purpose input that, when
configured, activates a general purpose output to perform any required function.
4.2.4 RS-485
An RS-485 terminal lets you easily connect multiple telephone, card access and
elevator restriction controllers across a network. The RS-485 connection is
situated at the bottom middle of the main controller board and consists of two
separate terminals, each for an input and output. The RS-485 terminal consists of
+ (positive), - (negative), and S (Shield) connections. See Figure 13.
