Only if the extinguishant control panel is switched to automatic release would these signals trigger the “Initiate”
stage i.e. visual and audible warning and after the time delay (30 or 60 seconds), the extinguishant release stage
i.e. power to the solenoid or detonator. An automatic discharge signal can be stopped during the initiate cycle by
switching the panel to manual release. If after investigation it is desirable to release the extinguishant then either
use the manual release call point or switch back to automatic discharge. The discharge delay cycle will start from
the beginning. The discharge will continue if a “Silence” key is pressed but will stop if the “Reset” button is
pressed.

DOOR SWITCH
A door switch monitoring circuit has been provided as an additional safety feature. This will sound the
panel’s
internal buzzer if:
1. The panel is in automatic release mode and the door is open, or the door lock monitor is in the open position.
2. The panel is in manual release mode and the door is closed or the door lock monitor is closed.
i.e. If a person enters a protected area and forgets to switch the extinguishant release from automatic to manual mode
the panel will warn them! To enable this feature the link (P13 on the main PC board) must be put to the correct
position.

The time between receipt of the 2

CPU Running:
This LED will remain flashing whilst the CPU board is operating correctly.
NB:
Please note that the LED colour has changed from flashing GREEN to
flashing BLUE.
Bell Fault:
This LED will illuminate, the internal buzzer will sound and the common fault contacts
will operate when a fault on one of the bell circuits is detected.
Maintenance Mode:
This LED will illuminate when one or more zones have been switched to walk-test
mode. The individual zones fault LED will also illuminate.
Supply Fault:
Supply fault will be indicated with a steady on Supply Fault LED. When a battery fault
occurs the panel will also indicate this with a steady on Supply Fault LED but with the
addition of a pulsing the Supply Fault LED 5 times every 20 minutes. In this condition
if a fault occurs the panel’s internal buzzer will be permanently on but in this instance
the buzzer can be silenced by pressing the silence button. It will again sound after
