CHAPTER 4
OPERATION
4-1 INTRODUCTION
This chapter addresses operation of individual ARIES NETLink
TM
systems. Instructions on how to
start up and operate a configured ARIES NETLink System, including how to distinguish the different
operating states, how to use the operator keys, entering passwords to access the system menus, and
what the Status Indicating LEDs mean are presented in this chapter.
4-2 OPERATING STATES
The ARIES NETLink system has two operating modes:
•Normal Mode
•Off-Normal Mode
Normal Mode is characterized by the absence of any initiating signals from either automatic detectors
or monitor modules, and by the absence of trouble conditions. The LCD Display will display the
message “Normal” (with time and date).
Off-Normal Mode is triggered by system events or operator interrogation via the keypad. Off-Normal
Mode operating states are listed in Table 4-1 below.
Table 4-1. Off-Normal Mode Operating States
Operating State Triggering Event(s)
Access-Via-Menu A operator uses the keypad to isolate initiating devices and/or outputs, list configuration
settings and the application program, adjust configuration settings, or manually initiate
testing procedures.
Trouble A report of a problem that could prevent the ARIES NETLink System from proper
operation. Typical trouble signals include: Lack of response from a configured device on the
signaling line circuit; Internal fault reported by a SmartOne® detector; Loss of monitoring
integrity of the installation conductors; Power-supply fault; and/or Loss of primary AC
power.
Alarm An automatic spot-type smoke or heat detector or a high-sensitivity smoke detector senses a
fire signature that is greater than the detector's programmable alarm threshold, or when a
monitor module programmed as a manual-alarm, manual-release, waterflow or general-
alarm point activates.
Pre-Alarm An automatic spot-type smoke, heat detector or a high-sensitivity smoke detector senses a
fire signature that is greater than a programmable, lower-level warning threshold but less
than the detector's programmable alarm threshold.
Supervisory A monitor module detects a condition such as gate-valve closure, low air pressure or water
level, or pump failure that could impair the operation of a building's fire suppression
system. It also enters this state when an operator isolates any initiating or control devices
or control-unit-based output circuits. This mode is primarily event-driven.
