EN 54 & ISO 7240 2-8 Zone Conventional Fire Panel - Installation & Configuration Manual
7.8 Primary and Secondary Delays
A day-time delay strategy can be implemented, if required,
which comprises two user-configurable delay periods to
allow a fire search to take place. These delay periods are
referred to as primary and secondary. On an auto detection
zone, every fire state places the panel in a full alarm, hold-
off state until the indicated fire event has either:
a. Been verified as true after the search and then
manually-terminated (at the panel or by operating an
MCP), or
b. The primary delay period expires, thereby automatically
operating the configured outputs (e.g. sounders).
If the ACCEPT pushbutton is pressed during the primary
delay period the delay to outputs is extended by the length
of the configured secondary delay. The maximum total
duration of a configured delay to outputs is 10 minutes,
even if the sum of the configured primary and secondary
delays exceeds this limit. Once the ten-minute delay period
has expired the outputs will be activated automatically.
7.8.1 Select Primary Delay Time
Specify the first stage of the delay to outputs. The default
is 30 secs. Press the push-button to specify another
primary delay period up to 120 secs in 30 sec increments.
7.8.2 Delay toTransmission Device
Activation of the transmission device output may be subject
to a delay. Press the push-button to toggle the
delayed/immediate action. The default condition is ‘delayed’.
7.8.3 Select Secondary Delay Time
Specify the second stage of the delay to outputs. The
default is 1 minute. Press the push-button to specify
another secondary delay period up to 10 minutes in 1
min increments.
7.8.4 Two-zone Override Delay
Delays to outputs are overridden when a second zone goes
into fire. This default can be changed so that a second
zone going into fire does not override an active delay.
