DSX-400DM
Duress Module
Application
The DSX-400DM duress module is designed to provide a
duress alarm for users of keypad systems. The module monitors the data 1 and 0
lines from a Wiegand output keypad waiting for the
asterisk (*) key hit. When the module sees the asterisk, the modules output
pulls low to activate an input on the DSX panel that would be defined as
“Keypad Panic”.
Implementation
To implement duress with keypad access, all keypad
codes must begin with a zero. This allows codes to be 4, 5, or 6 digits in
length. Set the “number of digits in a keypad code” selection under location to
be 1 more digit than the unique number to be used. All users will then press
zero ( 0 ) followed by the remaining digits of their
code. To signal a duress alarm the user will press the asterisk (*) instead of
the Zero and enter the rest of their code as usual. The panels sees the * as a
0 and will grant access for the user. When the DSX-400DM sees the asterisk (*)
it activates its output and trips the controller input that responds as programmed.
DSX-400DL Door
Latch Module
Application
The DSX-400DL allows the user to unlock with a card
read, latch the door open with a second card read and to re-lock (put to time
zone) the door with a third card read. Only users with the appropriate linking
level will perform this function. Non-authorized users have normal access
through the door.
Operation
On the first card read, output 1 on the DSX panel
activates the DPDT relay to unlock the door. Authorized user will pulse output
2 via a code to output link, if there is no second card read while the door is
unlocked, the door re-locks normally. If there is a second card read by an
authorized user, within the unlock time, then output 2 pulses again which
triggers the DSX-400DL to trip its output that is tied to an input on the
panel. This input is programmed to link to output 1 on a follow so that as long
as the input is faulted, output 1 is open. A third authorized read resets the
process and the door relocks.
