Special New Zealand functions
Note
: The functions in this chapter are valid for the New Zealand convention only.
18.1
Alarm devices
In the New Zealand convention only, the "
FIRE
" LEDs will indicate steady instead of
blinking when the alarm devices are disabled, see below.
18.1.1
Silence Alarms (inside switch)
On the CIE front, the button "
SILENCE ALARMS
" (P2)
is called the “
Inside switch
” and
functions are slightly different in the NZ convention as described below.
The switch toggles between two states:
Alarm devices disabled
When the button is pressed, all programmable outputs of type "Alarm devices" are
disabled, e.g. OWS or sounders, strobes, etc. and any new alarms will not re-
activate the warning devices.
Alarm devices not disabled
All programmable outputs of type "Alarm devices" will be enabled, i.e. any alarm
can activate the warning devices.
If the "
SILENCE ALARMS
" switch (inside switch) is left in its disabled state when the CIE
door is being closed, the buzzer will beep steady (continuously) and the message "
Silence
switch left active
" will be shown in the display. This feature is required in NZS4512 to
ensure that the door cannot be closed while the alarm devices are isolated. This message
has lower priority than fire alarms but higher than other disablements and faults.
Note:
The "
SILENCE ALARMS
"
switch on the front display has no function if the “
Silence
alarms
” Bulgin key in the FT1020G3 cabinet or in the remote fire brigade panel (see
below) is turned to the silence alarms position.
18.1.2
New Zealand FB Bulgin Silence switch (outside switch)
The New Zealand
FB
“Silence Alarms”
switch
is called the "
outside switch
" since it is
placed outside the CIE. The outside switch is a Bulgin key switch, it is connected to a
programmable input on NZ mimic display board (via 4582) with the trigger condition "
NZ
Silence switch
". The fire brigade key switch can be in two states:
1. The Bulgin key switch is turned ON
(i.e.
from not activated to activated state
).
All programmable outputs of type "Alarm devices" are disabled
