Input circuits capable of transmitting an alarm signal during a single open or a
non-simultaneous single ground fault on a circuit conductor shall be
designated as Style D or Class A. Similarly, output circuits capable of
activating during a single open or a non-simultaneous ground fault on a circuit
conductor shall be designated as Style Z or Class A. Commonly referred to
as redundant or 4-wire connection; this manual refers to 4-wire connections
as Class A wiring.
Input circuits incapable of transmitting and alarm signal beyond the location of
the fault condition (listed for Class A wiring above) shall be designated as
Style B or Class B. Similarly, output circuits incapable of operating beyond
the location of the fault condition shall be designated as Style Y or Class B.
This manual refers to 2-wire connections as Class B wiring
A detection scheme where two detectors must activate before the system
enters into the pre-discharge state; at least one detector from each detection
initiating circuit must be active.
A system component that originates transmission of a change-of-state
condition, such as in a smoke detector, manual fire alarm box, or supervisory
switch. This manual interchanges the terms initiating device and input device.
A circuit to which automatic or manual initiating devices are connected where
the signal received does not identify the individual device operated. This
manual interchanges the terms initiating device circuit and input circuit.
("Trouble" Yellow LED OFF) The system is in the normal state when the
power supply and all circuits are configured properly, connected, and
responding properly. The system remains in normal state until a trouble
condition occurs.
A fire alarm system component such as a bell, horn, speaker, light, or textual
display that provides audible, tactile, or visible output, or any combination
thereof. The device notifies building occupants of system status. This
manual interchanges the terms notification and audible appliance.
A circuit or path directly connected to a notification appliance(s). This manual
interchanges the terms notification appliance circuit and audible circuit.
A circuit designation given for wiring purposes. The amount of current flowing
through the circuit is unlimited vs. being limited, or power-limited. AC power
and Battery wiring is Non Power-limited.
A circuit designation given for wiring purposes. The amount of current flowing
through the circuit is limited (typically by fuse) vs. being unlimited, or non-
power limited. The SHP input and output circuits are power limited. The
circuit has a maximum power that flows through it or it current limits and
opens.
The time (in seconds) that the system will delay entering the release state
after the zone's detection type has been satisfied. Activation of an abort
switch will have an effect on this value, depending upon the abort type
selected.
("Alarm" Red LED ON, Piezo chirping) The pre-discharge state occurs when
the zone's detection type input conditions are satisfied (Cross Zone
Detection, Sequential Alarm Detection, or Single Detector Release). Upon
time delay countdown completion (unless delayed by a pertinent activated
abort input), the system leaves the pre-discharge state and enters the release
state.
("Alarm" Red LED ON, Piezo chirping) The release state occurs upon
completion of the pre-discharge state or upon activation of a manual release
input. At the start of the release state, output circuits configured for releasing
shall operate.
