5.2.1.10. A change of logical expression parameter is only possible on level 4 using special
hardware and software reasoned by complexity and labour content.
5.2.2. PSU functions.
5.2.2.1. PSU transforms 220V AC voltage to voltages required for the panel to properly operate, the
battery to charge, battery back-up power to be applied in the event of mains failure.
5.2.3. I/O functions.
5.2.3.1. I/O processes statuses and monitors 32 loops and 8 outputs, issues events when AL and/or
output change their statuses.
5.2.3.2. I/O provides loop voltage stabilization.
5.2.3.3. I/O allows a user to set 15/24 V for loops using jumpers.
5.2.4. BKI functions.
5.2.4.1. BKI displays the panel’s statuses and presents the interface for users to view information
about object conditions, view and set object parameters, view the event log, monitor objects
5.2.4.2. BKI contains groups of optical indicators, 4x40 alphanumeric display and multifunctional
keypad.
5.2.5. MC functions.
5.2.5.1. MC is designed to generally synchronize all the panel’s units, process logical expressions,
issue an object function call, monitor the BAT, maintain the event log, control the obligatory
outputs (according to EN54-2:2003) “Fire”, “Fault”, “Alarm”, “ Norm”, “Light”, “Sound”.
5.2.5.2. MC has a capability to connect auxiliary boards to expand the panel’s functions.
5.3 Operation principles
5.3.1. General overview
5.3.1.1. The panel monitors system object statuses (e.g. “AL”, “Power supply” and others) and
depending on status combinations, program settings and configurations, calls other objects control
functions of the internal sounder (e.g. “outputs”, “light indicators” etc.), external sounders
enablement, transmission of notifications to CMS.
5.3.1.2. The following modes are available on the panel: “Standby mode”, “ALARM”, “FIRE”,
“FAULT”, “DISABLEMENT”, “AUTHORIZED USER”, “PROGRAMMING”, ‘TEST”. The
panel can operate in several modes simultaneously.
5.3.1.3. The indicator lights are located on the front of the enclosure giving an overview of the
Panel’s current status (see Annex 1).
5.3.1.4. The 4 access levels are available on the panel.
Level 1 - general user controls. Available functions:
- testing the indicator lights and internal buzzer (called by pressing the TEST button);
- muting the internal sounder in FIRE, FAULT, ALARM modes (by pressing the button “Buzzer
OFF”);
- view of object current conditions;
- view of event log;
- output delay override (by pressing the Disable button).
Level 2 – authorized user controls. The access is limited by actions not requiring special
tools. The level can be accessed by entering the user’s number and his password. Each user has his
unique number and password. The password is drawn from [0] to [9] numbers, from 0 to 8
characters long. Enter buttons [0]…[9] and confirm entering by pressing the [ENTER] button.
For default passwords for all users please refer to Table 8.1.
Each authorized user can access controls under one or a few objects (AL and outputs).
Several users can access the same objects.
The following controls are available on this level:
- enablement/ disablement of certain ALs, available to the user;
- muting and restoration of outputs available to the user;
