Congratulations on your purchase of the Sensaphone 1800. The 1800 is
a powerful monitoring, alarm, and event logging system. It can monitor
equipment and environmental conditions using eight universal Zones 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 1800 also features user-recordable voice for ID and all
monitored zones, numeric paging, and built-in line seizure.
The Sensaphone 1800 is a fully programmable environmental monitoring
system for unattended or remote applications. The unit will monitor and
alarm on eight zones: these can be N.O./N.C.(Normally Open or Normally
Closed) contact, 4–20mA, or 2.8K or 10K thermistor (temperature sensor).
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 indicat-
ing the alarm status of the Zone. There is also an LED to indicate if the
Output is On, an LED for Phone In-Use status and an 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 pro-
gramming is retained even without power. The unit is capable of perform-
ing alarm event logging of the eight universal 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 1800.
The unit comes in a plastic NEMA-4 enclosure with tabs for wall or panel
mounting. Terminal connections for Zones, outputs and power are eas-
ily accessible from the front of the unit. The 1800 is powered by a plug-in
adapter and has a 6V 3.4AH rechargeable backup battery located behind
the panel. Circuitry in the unit will maintain precise charging of the battery
system. The unit also includes built-in Line Seizure capability to ensure
that the telephone line is available when necessary.
