Overview
Thank you purchasing your American Fibertek N-TAH. Please take a few minutes to
read these installation instructions in order to obtain maximum performance from this
product.
The AFI N-TAH device allows contact closure signals to be made accessible on and
linked over a network, with N-TAH devices acting as transparent bridges to link together
customer equipment. This permits contact closure signals – such as door opening
sensors, alarm buttons, or motion detectors – to be linked to remote alarm annunciation.
The N-TAH provides aux output relays which may be activated by alarm input events or
direct network commands. N-TAH devices can be linked together over a standard
Ethernet connection, making it possible to use a pre-existing LAN or the Internet for
device communication.
The N-TAH has a watchdog feature which allows it to monitor the function of up to two
network connected devices. The N-TAH can monitor a network device by periodically
sending ping requests to the device over the network. After a number of pings without
responses from the target device, the N-TAH takes an action which can be configured by
the user. This action can consist of either setting an aux contact output on the N-TAH
for a set period of time, sending a TCP message over the network to a user-defined
destination, or sending an alarm email to a user-supplied address
This feature permits the N-TAH to monitor an external piece of network-connected
equipment, and on detection of a failure trigger an alarm, notify a technician, or power-
cycle an external device through a relay.
The N-TAH also acts as an environmental sensor which is capable of monitoring the
temperature, relative airflow, and humidity at the location where the unit is installed.
The N-TAH is powered either from a PoE source over the UTP cable or from a 12Vdc
power supply which is provided with the unit.
