Introduction
There are seven possible input zones available on the 7845CZ. Zones 1 and 2 are located on
TB1-3 and are selectable for +V, -V, or EOLR modes, which can detect both pulsed and
steady signals. The pulsed signal is reported as an alarm on Zone 1 (Fire); the steady signal
is reported as an alarm on Zone 2 (Burg). The implied pulse count for zone 1 is fixed to 3
pulses. Similarly, the implied delay for zone 2 is 5 seconds. Additionally, the 7845CZ can be
programmed to detect a single pulse on the input, characteristic of a Panic indication on the
Lynx Control Panel. If the programming option "Lynx Panic" is enabled, the 7845CZ reports
an alarm on Zone 3* when it detects this single pulse. No restores are reported for this zone.
Zones 3*, 4, 5, 6 and 7 are voltage trigger inputs located on connector P2. If the Lynx Panic
feature is being used, do not connect Zone 3.
Programming
There are two methods of programming a 7845CZ.:
•
Using the Programmerless Registration Option (PRO), and
•
Using a 7720P Programming Tool.
Using the Programmerless Registration Option
The programming default values are listed in Table 5.
