15 Special New Zealand Functions
Note: The functions in this Section are valid for the New Zealand convention only.
15.1 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.
15.1.1 Silence Alarm Devices (Inside Switch)
On the CIE front, the button "Silence alarm devices" (P3) is called the "inside switch"
and functions are slightly different in the New Zealand 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 ALARM DEVICES" 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 ALARM DEVICES" switch on the front display has no function if
the “Silence Alarms” Bulgin key in the FT128 cabinet or in the remote fire brigade panel
(see below) is turned to the silence alarms position.
15.1.2 New Zealand FB 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 and connected to a
programmable input on NZ mimic display board (via 4582) with the trigger condition "NZ
Silence switch". The fire brigade Bulgin 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
135
, i.e.
they cannot be activated. The "Silence alarm devices" (inside switch)
has no function (see above).
 LED’s "Fire" (on FT128 front) changes from blinking to steady.
136
 The CIE built-in buzzer is silenced.
 A fault is generated.
137
FAULT: FB Silence switch active
135
Indicated by LED "Disablements".
136
This is valid also if the fire alarm is activated after the outside switch is turned ON.
137
Always latched, regardless of if faults are programmed to be not latched.
