Inputs
The DCM includes the following sensing inputs:
Door Contact (DC)
This input is a normal alarm zone input that has the same functionality as a
normal security zone type. It uses normal 1k/2k double balanced zone
wiring.
Request To Exit Contact (EC)
This input is a normally open contact. When activated it will allow
the door to unlock for the programmed duration. Additionally, the
door can be held unlocked indefinitely by holding the EC closed. In
this case, the relay activates only for the programmed duration but
the door propped alarm is held off. This can be achieved, for
example, by using a keyswitch wired in parallel with the normal EC
button.
Function Contact
This uses normal 1 k/2 k double balanced zone wiring. It
has the function of initiating a pre-programmed menu option
following a valid card. The normal use is to activate the
setting procedure via the reader but any menu option can
be programmed.
Tamper Inputs
The tamper circuits for both readers should be wired to the same tamper
terminals on the DCM. The two circuits are wired in parallel, each with its
own series resistor as follows:
The reader tamper is double-balanced.
• Reader 1 - 5.6kΩ
• Reader 2 - 12kΩ
Connecting a Wiegand Device
A standard Wiegand card reader or keypad can be connected to the DCM.
The keypad can operate in 4-bit and 8-bit burst mode.
Wiegand Reader Inputs
The wires from the Reader are connected to the Wiegand Reader Inputs (see
Figure 5-1). Refer to separate Reader instructions for method of wiring the
Reader to the DCM.
