EN54 & ISO 7240 2-8 Zone Conventional Fire Panel - Installation & Configuration Manual
7.7.2
Set Type
Digital input 1 is configured, by default, as a Delay Mode
input. Digital input 2 is configured, by default, as a Class
Change input. Press
push-button to select another type.
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
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.
7.8.3
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.
