8 CONFIGURING THE DRY CONTACT CARD
The following section details how to set up the dry contact cards. Communicator supports an eight dry
contact digital input card that can be programmed as a normally open / close dry contact input. These
inputs can be connected to a wide variety of sensors such as generator operation, magnetic door or
window, thermostat, etc.
1. Go to
SYSTEM > Digital Input.
2. Use the alphanumeric keypad to enter in the message and press
ENTER
.
3. Define
[N]
as
1
or
0
The '[N]' column's two possibilities:
•
0: Represents the open contact (Normally Open). If there is a change from the usual state
(closed state), an alarm occurs.
•
1
: Represents closed contact (Normally Closed). If there is a change from the usual state
(opened state), an alarm occurs.
The figure above serves as an example of a digital input program. The programmed line No. 1 is set as
normally closed for the house door. The message for this program is “door opened”. If the door opens,
the dry contact is disconnected and changes from 1 to 0. This change triggers the alarm and the
message “door opened” is sent to all addresses programmed in the Adding Names to the Address Book
(page 14).
