MDARM
Arming module on RS-485 serial line
for intrusion detection systems to be
used with an external reader
1 DESCRIPTION
MDARM allows arming and disarming an intrusion detection
system using the same user identification method used by
the access control system.
If the intrusion detection unit to which MDARM is connected
supports access-enabled users, it can also be used to tem-
porarily arm and disarm its gate.
MDARM and the access control system use different sets of
Wiegand readers.
