6 Delayed Day Mode Operation
• The panel can be configured to operate in a delayed day mode during the daytime for any specified
zone.
• During this time, high sensor signals received from a detector will generate a fire alarm message on
the panel but delay the ringing of the sounders. The panel will initiate a full fire alarm condition if no
action is taken on this warning within a specified period.
• If a second device indicates a fire alarm (from the same or another zone), the delayed day mode
function will be overridden and the panel will initiate a full fire alarm condition immediately.
• The use of delayed day mode must be configured at Level 3 by an installer / maintenance contractor
before it is available for use at Level 2.
• The delayed day mode can be configured to only operate at specified times of the day. The maximum
time allowed acknowledging stage 1 and stage 2 times can be programmed in intervals of one second.
• While the Delayed Day Mode Function is in the active period the Delayed Mode LED will be
illuminated.
6.1 Stage 1
• When a fire alarm condition is detected during delayed day mode, the internal buzzer will sound. The
sensor location (including zone location and point location text) will be shown on the display along with
a warning that the panel has entered stage 1 of a delayed alarm. The time remaining to acknowledge
the alarm is indicated and counts down from the programmed limit.

alarm.
