ANALOGUE ADDRESSABLE FIRE ALARM CONTROL PANEL SINGLE LOOP

Overview

The design of the control equipment shall offer a simple, cost effective & reliable product. The system shall be easily configured using ‘plug-in’ addressable loop driver and communication modules. Further ‘plug-in’ modules shall be available to allow the expansion of programmable inputs and outputs.

Analogue Addressable Detection Loop

The control panel shall provide a single analogue addressable detection loop, using one loop driver module.

Supported Detection Protocols

In accordance with the more common types of detection equipment available the supported protocols must include the following as a minimum:

Nittan AS PROTOCOL

The control panel shall support a single analogue loop with the capability to control up to 126 addresses.

Electrical Supply

The Power Supply shall operate on 230 VAC, 50 Hz, and shall provide all necessary power for the control panel.

In the event of a mains electrical failure, the fire alarm control panel shall have the capability of being supported in its intended state by standby batteries. The fire alarm control panel shall be fitted with an integral 0.7 Amp battery charger, current limited with DDP for 24 V lead acid batteries. The battery charger must be capable of being up-graded in capacity to facilitate larger systems.

Sounder Output

A minimum of two on-board sounder circuits shall be provided. The sounder outputs shall be fully programmable, monitored and short circuit protected. Each circuit shall support a load of 1 Amp. with a total panel loading of 1.3 Amps.

In the event that further sounder circuits are required it shall be possible to add further outputs to the panel via the detection loop and the dedicated RS485 peripheral bus. The peripheral bus shall support up to 15 additional 4 way sounder output cards if required.

Auxiliary Relay

The panel shall incorporate as standard 1 x failsafe fault output and 1 x fully programmable fire output each with volt-free changeover contacts rated at 24 V AC/DC, 1 Amp maximum. It shall be possible to add further programmable changeover relay contacts to the panel via the detection loop and the dedicated RS485 peripheral bus. It shall be possible to connect up to 400 fully programmable outputs to the fire alarm control panel in this manner.

Display, Indication and Operation

The panel shall have 14 general panel status LED’s. An alphanumeric liquid crystal display shall give 80 characters of information on a 2-line display. The display will be illuminated to aid viewing under dim ambient light conditions.

20 number zonal fire indicators (LED’s) and 20 number zonal fault/test/disabled (LED’s) shall be provided.

An on-board alphanumeric keypad with 17 keys shall allow the complete control and configuration of the system. Alternatively the panel shall be programmed using PC based upload/download software.

Four separate pushbuttons shall provide control of Sound Alarms (Evacuate), Silence/Resound, Mute/Accept and Reset, and shall be located adjacent to the main LED indication via entry level enable code.

Communication

A communications port with connections for an optional plug-in RS485 module shall be available for connection with peripheral devices. The peripheral bus shall support a further 126 addresses in addition to the detection loop. Peripheral devices shall include; display only and active repeater panels, remote printers, 8-way input cards and 4-way sounder & relay cards.

A dedicated RS232 port shall be available for both connections to a local printer and upload/download of configuration data via the manufacturer’s standard PC programming tool.

User Control Levels

The fire alarm control panel shall have three user control levels.

At all three levels, the LED displays shall indicate the condition of the installation, the zone LED’s shall indicate the location of any fire alarm or fault and the alphanumeric display shall provided detailed fire alarm or fault information.

Level 1 - All displays shall be functional, but the front panel controls shall be inhibited.
Level 2 - All displays and all front panel controls shall be functional. Changes to the system configuration shall not be accessible at this level. User Level 2 shall be reached by entering a unique 4 digit password from level 1.
Level 3 - All front panel controls shall be functional and full system configuration and programming shall be possible. User level 3 shall be reached by entering a unique 4 digit password from either level 1 or level 2. User level 3 shall be for use by the system installer / maintenance contractor.

A level 2 password shall not allow access to level 3 functions.

Up to 10 level 2 passwords shall be definable from level 3.

Commissioning Of Control Panels

On completion of the installation, the system shall be commissioned in accordance with the relevant standards, manufacturer guidelines and requirements of the system design. The fire alarm control panel shall have an auto learn facility that will allow the system to learn the number and type of devices that been installed on the detection loop.

A walk test option shall be provided for convenient testing of detectors and alarm initiating devices without continually having to reset the panel. This facility shall allow selected zones only to be tested without the need to have the entire system in walk test. During the period in which the fire alarm control panel is in the walk test mode, an active scrolling message shall remain on the LCD display at all times, indicating the zones in test mode.

Program Integrity

A program integrity option shall display the panel software version along with ROM and RAM checksums. The RAM checksum shall alter whenever the configuration is changed. For example, the checksum figure shall change when either adding or removing devices or changing text assignments. After the final configuration has been entered the program integrity shall be checked and the RAM checksum figure recorded.

Day Modes

The fire alarm control panel shall have the ability to automatically invoke different operating modes according to the time of day. Each mode shall have adjustable start and finish times. Outside of the designated start and finishing times, the panel shall revert to normal operation. The operating modes will consist of:

Delayed mode - During the day or night the alarm signal from the detection points shall be immediately recognised and identified on the panel display, but no outputs switched on until staged timers have expired. Manual call points shall always override this mode.
Sensitivity mode - Shall allow smoke and temperature detectors to use different pre-alarm and fire alarm thresholds during day and night mode.
Verification mode – Shall allow smoke detectors to tolerate transient alarms according to the programmed verification delay time during either day or night.

Event Log

The fire alarm control panel shall store the last 500 events. It shall be possible to set the event log to either "diagnostic" or "normal" mode. Normal is the default mode.

When in diagnostic mode the log shall record every event including single response failures from a device. The diagnostic mode shall aid the engineer to determine spurious or transient fault conditions including loop wiring and detector problems, particularly if these are intermittent.

Displayed Identification

During normal panel operation, when the fire alarm control panel is operating correctly, the LCD display shall display a message that identifies the system installer / maintenance company, this display shall feature up to 20 characters

If a fault occurs on the fire alarm control panel the LCD display shall automatically show a telephone number to call for assistance, this display shall feature up to 20 characters.

Cause-and-effect programming

The panel shall provide a flexible way of performing complex cause-and-effect programming. This shall include mapping individual detectors and call points to outputs as well as mapping outputs relative to zones in alarm.
