Suite Silence Configuration - Mircom FleX-Net Configurator Manual

Suite Silence Configuration

Introduction
The configurator allows the user to configure a combination of System Statuses, timers,
input zones and signal zones to satisfy the requirements of the Ontario Building Code with
respect to "Suite Silence".
The code allows the signals (speakers) in suites other than the suite where the alarm
occurred to be automatically silenced. But it specifies that the automatic signal silence
cannot occur until a minimum time has elapsed. It also specifies that the signals must
resound immediately if there is a subsequent alarm anywhere in the building, or if ten
minutes elapse and the alarm has not been acknowledged.
An excerpt of the code is reproduced below.
(13) Audible signal devices, within dwelling units that are wired on separate signal circuits,
need not include a means for silencing as required by Sentence(9) provided the fire alarm
system includes a provision for automatic signal silence within dwelling units, where,
(a) the automatic signal silence cannot occur within the first 60sec. of operation
•
or within the zone of initiation,
(b) a subsequent alarm elsewhere in the building will reactivate the silenced
•
audible signal devices within dwelling units,
(c) after a period of not more than 10 min., the silenced audible signal devices
•
will be restored to continuous audible signal if the alarm is not acknowledged...
Timers
Two timers were added to support Suite Silence. And the existing Signal Silence Inhibit timer
also plays a role. The duration of all three timers can be set on the Job Details form. The
conditions which start and stop these timers are also described there.
Auto Resound (mins) - This timer specifies the time, in minutes, after which the
•
signals will resound if an alarm remains un-acknowledged. The configurable
range is from 5 to 12 minutes with a default of 10 minutes.
New Alarm (secs) - This timer is started by a new alarm. The configurable range
•
is from 10 to 120 seconds, in 10 second steps with a default of 60 seconds.
Signal Silence Inhibit (secs) - This timer already existed prior to the introduction
•
of Suite Silence and specifies how long the signals must sound before they can
be silenced by any means.
