Indications
Common fire = Global fire indication
Common fault = Global fault indication
Zones 1 – 4 = Global zone indication
All other indications work at the local level
Option Switches
As a rule, all option switches function at the local level only, e.g. if on panel A the option switch No. 8
(zonal bells) is selected ‘on’, this will cause sounders on panel B, C & D to pulse when the fire is on
either B, C or D panels.
The sounders on panel A will sound continuously only when an alarm is received from one of ‘A’s
zones.
With due consideration at the design stage, networking could provide useful solutions.
