Basic concepts of control panel programming
12.1 Overview
One of the tasks of the SmartLoop control panel is to trigger “events” that indicates its own status,
and that of its connected fire alarm devices. The “events” are signaled on the LEDs and display and
then saved to the events log. The other task is to control, by means of the loop output devices and the
NAC outputs, its peripheral devices (bells, pressure valves, remote LEDs, etc.).
The first task “monitoring”, involves handling fault conditions and status changes of its devices.
Analogue devices activate when their values exceed their Early Warning and Alarm thresholds,
whereas, digital devices activate when they switch ON/OFF.
Each activation can be “controlled” by means of the programming options which generate various
event types: Alarm, Pre-alarm, Monitor, Supervisory, Early Warning or generic Activation. Faults,
however, always generate Fault events (unless you program the system to ignore specific faults).
All events are saved to the events log (which can be viewed via computer or control panel) and are
signaled on the display and LEDs (refer to paragraph 12.2 The events).
Each event influences the 16 device statuses (Alarm, Pre-alarm, Evacuate, etc.) and modifies the
respective values.
The second task “control”, relates to the device status and is handled by the zones. The zones
represent environmental groups of devices. Each zone receives the “filtered” status of each of its
devices (for example, a device in Alarm status may send an Evacuate signal to its zone). The zone
then deals with the filtered signals in accordance with the pre-set delays (for example, the zone
receives an Alarm signal but goes into Pre-alarm status for the pre-set time) and logical and
mathematical equations (the groups), and subsequently acts on the control panel or loop outputs.
Refer to paragraph 12.3 The signals.
In this way, each zone is independent and operates autonomously on each separate output.
In order to allow the “control” feature to function properly, it must be programmed as follows.
• For each input device:
- which of the 16 signals (e.g. Alarm, Pre-alarm, Evacuate, etc.) it must activate on the control
panel and the zones;
- which groups it activates (maximum 3);
- which constraints it enforces on the control panel (e.g. Enforce Silence status) or zones (e.g.
Enforce Evacuatestatus on zones in Alarm status).
• For each zone:
- the delays that determine the zone Alarm and Evacuate signals on reception of Pre-alarm or Alarm
signals from the device;
- the groups (maximum 3) that are activated by certain signals.
In this way the zone determines which type of control algorithm to apply in accordance with the
signals received.
• For each NAC output and for each output device on the loop:
- which signals activate the output, whether received from the control panel, zones, other devices
or from the device itself or the groups (maximum 3).
