Output Event Suppression - Honeywell Notifier NFS2-3030 FACP Programming And Operations Manual

Operation
All network nodes will go through a 10 second decouple time. An MN reset may require up to 60 seconds of decouple time depending on
the complexity of logic equation evaluations.
Fire Events Only Present in System
When MN events have the highest priority and only fire events are present in the system, pressing the panel's Reset button will reset the
system.

4.3 Output Event Suppression

Event suppression results from automatic panel suppression as well as programming. Following is a list of factors to keep in mind during
system setup to achieve the desired event suppression.

General Considerations for MN and Fire:
• General zones and logic zones are not suppressed by an MN or Fire event. Output device and zone map programming determine
whether an output will be suppressed, not the state of the zone.
• A general zone tracks the type of event (i.e. MN or Fire) that initiates its activation, and its outputs will be suppressed or resounded
automatically by panel programming. Suppression of outputs activated by general zones is dependent upon the event type that
initiated its activation.
• Each general zone must be dedicated to a single event type. If a general zone is used for MN, that zone can not also be used for fire,
security, etc..
• An output device, such as a horn or strobe, can be mapped to multiple zones. The zones can be general zones, special function
zones, logic zones, or releasing zones. These zones do not need to be the same event type: for example, a general zone used for MN
and a general zone used for Fire can be mapped to the same strobe.
• A logic zone does not automatically track the type of event that initiates its activation. Logic zones must be written to ensure
suppression. See examples below.

MN is the Highest Priority
Zones:
• It is crucial that logic zones be written conditionally to ensure suppression. The following examples illustrate two ways to achieve
suppression using logic equations.
Example 1:
Output suppression using Logic Zone Programming and Special Function Zone ZF20
Logic equation ZL1 = AND(OR(Z10,Z11,Z12),NOT(ZF20)), mapped to an output that is used for fire and suppressed during MN.
Z10, Z11, and Z12 are dedicated fire zones.
ZF20 is the MN alarm zone.
If Z10, Z11, or Z12 is active, and ZF20 is not, ZL1 will go active.
If any MN alarm occurs, ZL1 will go inactive, and any outputs mapped to it may be suppressed.
Example 2:
Output suppression using Logic Zone Programming and MN-dedicated General Zones
Logic equation ZL2 = AND(OR(Z10,Z11,Z12),NOT(Z2)), mapped to an output that is used for fire and suppressed during MN.
Z10, Z11, and Z12 are dedicated fire zones.
Z2 is an MN alarm zone.
If Z10, Z11, or Z12 is active, and Z2 is not, ZL2 will go active.
If Z10, Z11, or Z12, and Z2 are active, ZL2 will go inactive, and any outputs mapped to it may be suppressed.
Outputs:
• All outputs used for MN must be programmed as non-silenceable. This includes those outputs that are shared between MN and
other events, such as Fire.
• Dedicated Fire outputs can be programmed as silenceable or non-silenceable.
• All silenceable outputs will be suppressed at the start of an MN event.*
• All devices programmed with strobe Type IDs, as well as all intelligent sounder bases, will be suppressed regardless of silenceable
programming at the start of an MN event.*
*Zone map programming will then be re-evaluated, and if a device contains ZF20, or any general zone dedicated to MN that is
active, in its zone map, it will be re-activated.
• An output programmed with a releasing Type ID, or programmed with an active releasing zone in its zone map, will not be
suppressed.
Audio:
• Fire sequences playing on a DAL (digital audio loop) will be silenced, and the DVC will sound the MN Active Tone while fire is
suppressed.
• Fire sequences on a DVC will not sound, and the DVC will sound the MN Active Tone while fire is suppressed.
Drill and custom drill operation is blocked while fire activations are suppressed. This prevents activation of fire outputs while a Mass
Notification is in progress.
When an MN alarm is cleared, suppressed outputs will reactivate, even if they were silenced prior to being suppressed
