Option Description
following output modules can be configured to unlatch latched outputs:
E-ISO, E-IDC1A, E-IDC1B, or E-IDC2B
Waterflow: For connecting vane type and pressure flow switches.
Activations are considered as alarms. A 16-seconddelay applies to
waterflow device types. NACs activated by waterflow device types cannot
be silenced until the activated devices are restored to normal via a panel
reset. Circuit cannot be restored until devices are restored to normal and
the panel is reset. Waterflow activations do not invoke in-suite signal
silence.
Waterflow Class A: For modules wired to Class A circuits composed only
of waterflow alarm switches. Modules with this device type initiate active
(alarm) events if the circuit remains shorted for at least 16 seconds. NACs
activated by waterflow device types cannot be silenced until the activated
devices are restored to normal via a panel reset. Circuit cannot be
restored until devices are restored to normal and the panel is reset.
Waterflow activations do not invoke in-suite signal silence.
Relay module
Relay nonsilence: For relay devices that do not follow signal silence.
Relay with silence: For relay devices that follow signal silence.
Latched outputs
Supervised outputs (latched) (SupOut Latch): For Class B latched output
modules that output an unsynchronized signal. Does not follow signal
silence.
Continuous nonsilenceable (latched) (Cont NS Latch): For Class B latched
output modules that output an unsynchronized signal. Does not follow
signal silence.
Continuous nonsilenceable ClsA (latched) (Cont NS ClA Latch): For Class
A latched output modules that output an unsynchronized signal. Does not
follow Signal Silence.
Supervised outputs ClsA (latched) (SupOut ClA Latch): For Class A
latched output modules that output an unsynchronized signal. Does not
follow Signal Silence.
Relay nonsilenceable (latched) (Relay Latch): For Class B relay devices
functioning as latched output devices. Does not follow signal silence.
Relay nonsilence NO (latched) (Relay NO Latch): For relay devices
functioning as latched output devices that close when activated. Does not
follow signal silence.
Relay nonsilence NC (latched) (Relay NC Latch): For relay devices
functioning as latched outputs that open when activated. Does not follow
signal silence.
NAC module
Genesis audible/visible silence: For Genesis and Enhanced Integrity horns
and strobes. Genesis and Enhanced Integrity appliances maintain
synchronization per UL 1971. For Genesis devices only, connected horns
can be silenced and strobes turn off.
