N2 Dialer Module
The N2 Dialer Module (NDM) provides a low-cost
method of connecting your facility management
system to application specific digital controllers
located in remote buildings. The NDM’s two-way
telephone dial-up connection provides for alarm
notification, manual command changes, controller
uploads/downloads, and remote system servicing.
The NDM is ideal for locations that are difficult to
travel to and have basic monitor and control
requirements, such as boiler failure detection and
temperature monitoring. The NDM provides for
improved operator response to alarm/trouble
conditions in remote buildings. And since
communication can be established easily through
the public telephone system, service response
time is improved and service costs reduced for Figure 1: N2 Dialer Module
these types of facilities.
Features and Benefits
❑ Efficient Alarm Notification Polls devices on a remote network continuously
and dials out to the local facility management
system or printer on alarm.
❑ Easy Installation Mounts directly to a wall or within Johnson

other equipment. It may also be used
unmounted by placing it on a desk or tabletop.
❑ Economical Operator can be notified of a remote alarm from
an inexpensive printer; no headend system is
required.
❑ Uses Public Telephone Lines With a Hayes® compatible modem, plugs
directly into the jack of a standard dedicated
telephone line. No special wiring is needed.
❑ LED Indicator Lights Monitors power-up diagnostics and allows user
