13. Select switch number 1 for Node 3, and then click Add.
14. Click Close.
The switches are now correlated as follows:
• Node 1 switch number 0 <--> Node 2 switch number 0
• Node 1 switch number 1 <--> Node 3 switch number 0
• Node 2 switch number 1 <--> Node 3 switch number 1
19.45 Suite Silence
You can configure a combination of system statuses, timers, input zones, and signal zones to
satisfy the requirements of the National Building Code of Canada with respect to suite silence.
The code allows the signals (speakers) in dwelling units in zones other than the zone where
the alarm occurred to be automatically silenced. However, it specifies that the automatic signal
silence can only occur after a certain amount of time. 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.
For example, consider a 3 floor residential building with a speaker in each suite and a speaker
in each hallway. If an alarm occurs on floor 3, the following events occur.
1. All the speakers sound.
2. After 60 seconds, the speakers in the suites on floors 1 and 2 are silenced. The
speakers in the hallways on floors 1 and 2 continue to sound, and all the speakers on
floor 3 continue to sound.
3. After 10 minutes, if the alarm is not acknowledged, all the speakers sound again.
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 60 sec. of operation or
within the zone of initiation,
• (b) a subsequent alarm elsewhere in the building will reactuate the silenced audible
signal devices within dwelling units,
