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. 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
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.
WIRING SENSORS AND TRANSDUCERS
The 1800 Zones are compatible with NO/NC dry contacts, 10K
thermistors, and 4–20mA transducers. To prevent an alarm from
occurring while wiring the sensors, it is recommended that the zone
be disabled [SENSOR ON/OFF] + [Zone #1–8]. After wiring all of
your sensors you will need to configure the zones using the [SET] +
[CONFIGURE] command. See Chapter 4 for more information on
Disabling sensors and Configuring Zones.
Recommended sequence for adding a new sensor:
1. Disable the zone.
2. Wire up the sensor.
3. Configure the zone.
4. Enable the zone.
NOTE: If a false alarm occurs while wiring a sen-
sor, you can quickly acknowledge it by pressing
the [ALARM/CANCEL] key and entering [11234]
+ [ENTER]. This is the default acknowledgment
code for user #1. See Chapter 5 for more informa-
tion on User Acknowledgment Codes.
Temperature: The unit will accept 10K or 2.8K thermistors.
These should be wired to a Zone terminal and the adjacent ground
