CHAPTER 1: INTRODUCTION
Congratulations on your purchase of the Sensaphone 2800. The
2800 is a powerful monitoring, alarm, and event logging system.
It can monitor equipment and environmental conditions using four
wired universal Zones and four wireless sensors with scaleable
range, built-in power failure detection, sound level monitoring,
and one relay output for manual control, or automatic control from
alarms. The Sensaphone 2800 also features user-recordable voice
for ID and all monitored zones, numeric paging, and built-in line
seizure.
The Sensaphone 2800 is a fully programmable environmental
monitoring system for unattended or remote applications. The
unit will monitor and alarm on four wired zones: these can be
N.O./N.C.(Normally Open or Normally Closed) contact, 4–20mA,
or 2.8K or 10K thermistor (temperature sensor). In addition the unit
will accept signals from up to four wireless sensors. The unit will
also monitor AC power, sound level, and battery condition. On the
front of the unit are LED indicators to show the operating status.
Each zone (including power, sound and battery) has a status LED
indicating the alarm status of the Zone. There is also a LED to
indicate if the Output is On, a LED for Phone In-Use status and a
LED for System-On status.
The unit is programmed using the built-in keypad and voice
response menus. All programming is stored in nonvolatile memory
so that all programming is retained even without power. The unit
is capable of performing alarm event logging of all eight Zones,
power, and sound. The event logging (history) is also stored in
nonvolatile memory. A battery-backed real-time clock is also
included to time-stamp logged events. The alarm event history
can be heard through the built-in speaker or remotely over the
telephone. A complete status report of all monitored conditions can
also be heard simply by calling the 2800.
The unit comes in a plastic NEMA-4 enclosure with tabs for wall or
panel mounting. Terminal connections for Zones, outputs and power
are easily accessible from the front of the unit. The 2800 is powered
