After the initial address is set, the addresses of control enable pin, emergency start
button, emergency stop button, gas extinguishment and addresses reserved for future
use
will be automatically set in sequence according to the number of zone control
board. No matter how many zones are configured to the control panel (1 ~ 6), control
enable pin (alarming action when disabled) occupies an address, which is the initial
address. Each zone occupies four addresses:
(1) Emergency Start Button (action).
(2) Emergency Stop Button (action).
(3) Gas extinguishment (pressure switch action and local fault).
(4) Reserved for future use.
The number of addresses occupied by the control panel = n x 4 + 1 (n is the maximum
quantity of zones, 1~6).
For example, in Fig. 5-5, S1 is set as 0, then the initial address is 1, in other words, the
number of the control enable lock is 1. The addresses of other points are shown in
Table 2.

5.6.3 Setting Delay Time
Because extinguishing device will finish gas release instantaneously on receiving valid
start command, improper operation will result in great losses, even loss of life; On the
other hand, it will affect the fire protective ability of some important places in a certain
period. For these reasons, the control panel is designed with delay started feature.
When receiving start request, it will delay for a certain time, and give command when
delay ended. To meet requirements under different conditions, the delay time can be
set by code switch S2 on the main board (see Fig. 5-6) within 0s
～
45s.
