The NK-AD-300 Digital Alarm Communicator
Transmitter/Dialer Module allows Nittan’s SPERA
Series Fire Alarm Control Panels to transmit Alarm,
Supervisory and Trouble information on two telephone
lines to a monitoring facility.
The NK-AD-300 is powered by the host fre alarm control
panel and communicates with the fre alarm control panel
via an RS-485 data link. The Digital Communicator can
be programmed for dual line operation and uses the
Security Industry Association (SIA) and Ademco Contact
ID reporting protocols.
The NK-AD-300 can be confgured locally via the onboard keypad and the CFG-300 Confguration Tool or with a UIMA programming tool and a computer with an
available serial or USB port. In addition the NK-AD-300
can be remotely confgured using a personal computer
with a modem.
The NK-AD-300 can be confgured for either DACT
or UDACT operation. In DACT mode the Digital
Communicator reports common alarm, trouble and
supervisory information. In UDACT mode the Digital
Communicator reports point specifc information. In
addition the NK-AD-300 is equipped with the ZDACT
feature that allows for input circuits on the SPERA panel
to be grouped into software zones for the purpose of
reporting to a central monitoring station.
