SENSAPHONE 1800 User’s Manual
The 1800 also includes a 3V lithium battery to retain the date and time
when main power is off. The lithium battery should provide 8-10 years of
service life.
Note: Have batteries serviced by qualified service personnel only.
TELEPHONE LINE
Connect the 1800’s Phone jack to a standard 2-wire analog phone line. The
unit dials using pulse or tone, with loop start only. The 1800 will recognize
ringer frequencies from 16 to 60 Hz and will operate with all standard ana-
log telephone systems that accept pulse or tone dialing.
Certain private telephone systems and public switching equipment may not
accept the unit’s dialing or may generate an unacceptable ring signal. In
those cases, a dedicated line may be required for the unit. Consult the sup-
plier of your telephone system if you encounter problems.
Note: Never install telephone wiring during a lightning storm. Never
install telephone jacks in wet locations unless the jack is specifically
designed for wet locations. Never touch uninsulated telephone wires
or terminals unless the telephone line has been disconnected at the
network interface. Use caution when installing or modifying telephone
lines.
LINE SEIZURE
Line seizure gives the 1800 the ability to “seize” the telephone line when it
needs to dial out. For example, if an emergency occurs which puts the 1800
in alarm mode, the unit will be able to dial out even if a telephone has been
left off the hook. To the right of the LINE terminals is another set of termi-
nals labeled EXT. These terminals can be used to share the line with other
devices (telephone, fax machine, modem) and to give the 1800 priority in
the event of an emergency. To make use of this feature you must have all
the extension devices originate from the EXT terminals. Whenever the unit
must make an alarm phone call, the unit will disconnect any current phone
calls and seize the line for its own use. The unit will continue to seize the
line until the alarm has been acknowledged.
Note: The Line Seizure Kit is not required for the 1800 seizure capability
to function correctly. The Kit allows the disconnection of the 1800
system from the telephone line while ensuring continued telephone
operation—useful if the 1800 is, for instance, temporarily removed for
service.
