unit. Consult the supplier of your telephone system if you encounter
problems.
CAUTION: 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 dis-
connected at the network interface. Use caution when
installing or modifying telephone lines.
Line Seizure
Line seizure gives the 1400 the ability to “seize” the telephone line
when it needs to dial out. For example, if an emergency occurs
which puts the 1400 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 terminals labeled EXT.
These terminals can be used to share the line with other devices
(telephone, fax machine, modem) and to give the 1400 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. To ease installation, an optional accessory is
available (FGD-0060 Line Seizure Kit) which provides an RJ31x
modular wall jack, cable, and wiring instructions.
NOTE: The Line Seizure Kit is not required for the
1400 seizure capability to function correctly. The
Kit allows the disconnection of the 1400 system
from the telephone line while ensuring continued
telephone operation—useful if the 1400 is, for
instance, temporarily removed for service.
WIRING SENSORS AND TRANSDUCERS
The 1400 Zones are compatible with NO/NC dry contacts, 2.8K and
10K thermistors, and 4–20mA transducers. To prevent an alarm
from occurring while wiring the sensors, it is recommended that the
zone alarm be disabled [SENSOR ON/OFF] + [Zone #1–4]. After
wiring all of your sensors you will need to configure the zones
