After the settling delay completes, the panel begins a window delay and starts
watching for another on-board or 2-wire smoke zone trip. The period of this window
is determined by the value in seconds programmed in location 0249. The default
value is 120 seconds. Location 0249 must be 120 (120 seconds) for a UL installation.
Any trip during the window period results in a smoke alarm activation. Note that
this activation need not be from the same zone that started the smoke verification
sequence; any other on-board or 2-wire smoke zone that trips during the window
delay will cause a smoke alarm activation. This is a fail-safe so that if the initial
detector that started the smoke verification sequence has been damaged, some other
detector will hopefully be tripped.
Once the smoke verification sequence starts a smoke alarm, all delays are cancelled
and the sequence begins again for the next on-board or 2-wire smoke zone trip.
It should be noted that since smoke verification only applies to on-board and 2-wire
smoke zones, smoke zones from any other source will immediately trip a smoke alarm
and cancel the smoke verification sequence.
Speaker (Bell) Supervision
Speaker supervision requires the connection of a jumper wire from the speaker output terminal (INT or EXT) to a
selected hardwire input terminal and two 4.7K resistors in parallel be connected between the (AUX+) terminal
and the selected hardwire input terminal where the jumper is attached.
UL requires that one internal speaker, excluding RK series keypad speaker(s), must be supervised and connected
to the "EXT" and "COM" terminals. Supervised speaker(s) must be connected to one of the 8 on-board hardwire
inputs. The option programming location for the hardwire input to be supervised as a speaker zone (see page 22)
must have a value of 008. With a value of 008 programmed, an open or short in the speaker wire will cause a
trouble condition. To have a trouble condition be treated as an activation, program 024 in the hardwire input
option location.
If multiple speakers are connected are needed for supervision, they must be connected in series. This way, any
break in the loop will be properly detected. All speakers connected in series must have similar ratings.
NOTE: The panel common must not be connected to an earth ground. The speaker supervision
will not detect aground fault if the panel is grounded. Earth ground is not required in UL
installations.
If a loop programmed as a speaker supervision zone does not have the option set to "treat trouble as an
activation" the panel will display trouble at the keypad and send trouble/ trouble restore reports to the central
station.
If programmed to "treat trouble as activation", the panel will treat the speaker supervision as any other zone.
You may program the zone to any legal zone type.
