Sophisticated hardware and software have created a control panel with unprecedented facilities in a compact housing. The control unit is available with or without an integrated control panel.

The control unit communicates fully bidirectionally with the entire range of Argina detectors, manual fire alarms, input/output modules and gas detectors.

Fire alarm installations with from 1 to 10,000 detectors can be connected to the GMC+ control unit.

Control units can have practically unlimited connections to each other or to one or more control panels via the ArgNet.

Where necessary, ArgNet interfaces can be used to enable local connections:

• PC via a USB interface
• Pager via RS232 interface
• Printer via RS232 interface
• LON via ArgLon interface

The control panel can be surface mounted or built in. The control panel has its own 230V power supply/charger and a backup battery. Only a connection to the ArgNet is required.

The control unit has a built-in audio interface, which is used to connect it to a PA system. The

control unit can send pre-recorded messages and even indicate where the alarm has occurred.

It can be equipped with a modem module giving the following options:

• automatic telephone fi re report with voice
• automatic telephone connection to compatible control rooms
• remote maintenance and updating of the control unit
• connection to remote stores, shops, etc.

The bi-directional loops are physical twisted pairs and are fully compatible with short-circuit

isolators. If the loop is confi gured as a closed loop, then it will be fed from both sides in the event of a line break, so that all detectors and manual alarms remain active. If a short circuit occurs, only that part of the loop between the two short-circuit modules where it happens will be disabled.

The loops interface with analogue detectors, which are identifiable measuring devices that continuously send their analogue readings to the control unit via digital communication. The control unit uses several successive readings and specific algorithms to determine whether a detector is sending an alarm or is faulty.

The control unit interprets data in the long term as well so that preventive maintenance can be

carried out. The language the control panel uses for messages can be changed at any time by using a single key. A precise indication of the location is given in each report (this text, provided by the user and up to 40 characters long, remains unchanged).

The control unit has 11 freely-configurable relays as standard. It can have 2 additional relay PCBs fitted as an option, each one having 12 additional relays (1A/relay), Relays can be located remotely by using input/output modules in the loops.

The control unit has 4 universal inputs:

• 2 monitored inputs for connecting, for example, an external reset switch.
• 2 universal optocoupler inputs.

The inputs can be expanded, for example with 4 additional inputs per relay extension PCB, or with remotely-located input/output modules.

The control unit can be confi gured fully and quickly using the ConfiGMC program on a PC.

A laptop PC can be plugged into a control panel for commissioning or during maintenance

without opening the control unit. All internal readings can be retrieved via the laptop, for example the readings from the detectors, the power consumption in the loops and the

power consumption by external users.

Simple settings such as delay times can be entered from the control panel.

The LCD backlight is switched on automatically as soon as a key is pressed or an alarm or a fault is reported.

There are extensive scroll facilities:

• a normalised alarm scroll function for the fire brigade or the user
• a full scroll function with all reports for the user

The various authorisation levels (EN54-2):

• Level 1: Four keys accessible by everyone: alarm scroll, lamp test, buzzer silence, language setting.
• Level 2: The other keys are accessible when the special key is inserted in the keypad and is turned in the right direction.
• Level 3: Some F-key functions are possible only after a code has been entered.
• Level 4: By plugging in a laptop with the Confi GMC program.

The ArgNet network connects to the GMC+ fire alarm control units, the control panels and the ArgNet interfaces. The ArgNet network uses screened twisted pair cables and is not polarised.

A second cable, connected to the ArgNet Backup clips, can be used for increased reliability or if an inspection authority requires it. If communication on the first network is not possible, all units switch over to the backup network, so that the entire system remains operational, even in the event of a line break or a short circuit in a network.

-Argina detectors have an easy-to-fit universal detector base incorporating the necessary connectors, into which the detector head is plugged. The detector head can be fitted to the base and locked without the use of special tools.

-The basic principle of the analogue system is that the detectors are sensitive addressable measuring devices that are in continuous communication with the control unit. The detectors send their measurements continuously to the control unit, which stores them in a data bank. The alarm status can be determined from these measurements, using software algorithms and the specific parameters for each detector (including operating mode and delay. alarm level). In that case both red LEDs light up.

A connection for an auxiliary indicator is provided as standard and is short-circuit protected.

-The detector can be set up via programming to detect according to one or more criteria. This is done partly in position in communication with the control unit and/or using an optical remote control. The detector contains no switches, all on-site parameters being stored in an EEPROM. The detector's address is assigned via the remote control. The status of all measuring devices can be verified at any time via the control unit and/or an optical remote control.

-The unique bi-directional communication protocol between the control unit and its detectors filters out any parasitic interference in such a way that using screened cable is unnecessary. Each detector has short-circuit protection that isolates it in the event of a detector fault.

Working principle:

As an optical detector: based on the Tyndall effect. The measuring chamber contains an infra-red light source and the photoelectric diode that acts as a receiver, located such that they are not aligned optically. If visible smoke enters the detector, the smoke particles reflect the infra-red light, as a result of which the detector sees pulses.

An electronic switch uses these to determine the smoke concentration (conforming to the EN54-7 standard).

As an ionic detector: reacts to visible as well as invisible smoke/gas. The working is based on the ASOS system, in which the ionic measurement is determined in a unique way without a radioactive source. It is less sensitive to airflow than a detector with a radioactive source and has improved working at higher humidity (conforming to EN54-7).

• Combines analogue pointdetector and air-sampling detector
• Utmost sensitive fire detection
• Simple cabling
• Suction through a thin flexible hose
• Deployable in both clean and very dusty environments
• Filters are easily replaceable by means of a cassette system

The detector combines the advantages of an analogue point-detector with those of an air-sampling detector:
- Sensitive fire detection, even when the airflow is low.
- Simple cabling, no piping system: suction through a thin (Ø 6mm) flexible hose.
- Full identification and measurement data per suction point.
- Optical, ionic (without the use of a radioactive source), temperature and CO measurement values.
Compared to other air-sampling systems that detect fire in ‘clean rooms’, the A4S was especially developed to also function in a very dirty and dusty environment.
The detection is individual: There is a single suction point per A4S. Via the bi-directional fire-detection loop, all the measurements and parameters are transmitted to the fire detection
control unit.
It is possible to connect 25 A4S detectors to a single bi-directional fire detection loop.
Each A4S contains an extensive range of fire detection sensors:
- Optical smoke measurements
- Ionic measurements (without a radioactive source)
- Temperature and rising temperature at the suction mouth as an option

- Multi-sensor measurement values (optical detector with increased sensitivity in case of temperaturerise)
- CO detection as an option. The measured values from all these sensors can be retrieved from the fire alarm control unit.
The alarm bars can be adjusted from the fire alarm control unit per sensor type and per A4S.
Each A4S contains extensive operational checks:
- Measuring underpressure: In order to immediately report any blockage or leaks in the suction system.
- Measuring suction capacity: To be able to check the suction system and the suction filter.
- Measuring the filter bore: So that the filters are not replaced too soon nor too late.
- Measuring pump amplitude: A check of the suction system.
- Measuring the power supply voltage and current in the suction system: To be able to check
the power supply remotely.
The A4S is built as an internal modular model.
The filters can be changed manually: They slide into and out of a collector block. Maintenance is therefore simple.

Maintenance:
The design of the filters allow you to carry out maintenance service only once per year. The service period for the internal BOSEC certified IOT detector is every five years. These are realistic figures based on tests carried out in a train tunnel (Kennedy Tunnel in Antwerp). However, the actual maintenance will depend on the specific environment.
If necessary, the modules can be easily and quickly replaced on the spot. Since the fire alarm
control unit receives all the measurements of the operational parameters continuously, the maintenance software can provide detailed warnings.
The suction point is designed as a suction mouth:
The relative small circle-like suction mouth has a diameter of 60 mm. Its form makes it very sturdy.
The stainless steel mesh cupola prevents blockage from flying dirt. There is a nipple for connecting the flexible hose. The cast temperature sensor is connected with a cable attached by casting. There are two fixing holes with 5mm diameter at a centre distance of 50mm.

Suction hose:
The hose is Festo brand, type PU-4-BL (part number 6204); external diameter is 6mm, internal diameter is 4mm. The suction hose can be between 0 and 20m long. The suction hose usually slides into a tube (minimum 5/8”) together with the cable for the temperature sensor.

Minimum tube radius: 8cm
Suction detector:
Connections with the suction mouth:
- Equipped with a fast connection to the flexible hose of the suction mouth
- The cable of the temperature sensor is attached to the connector in the detector.
Other connections:
- Connection on a bi-directional fi re detection loop: 2-polar. Two sets for the sake of simplicity:
two clamps for the incoming loop (E+/E-) and two clamps for the outgoing loop (0+/0-).
- Connection to the power supply voltage 24VDC: 2-polar. Two sets for the sake of simplicity: two clamps for the incoming power supply voltage (P+/P-) and two clamps for the outgoing power supply voltage (P+/P-).

• No broken glass when activated
• Resettable with key supplied
• Installer-friendly fitting
• Good feedback on activation
• Built-in short-circuit isolator
• Addressable via Laserbox remote control
• Easy to test
• Two-wire system
• Operationally reliable

There is no danger of injury by glass splinters: the polycarbonate window does not break but clicks in when operated. There is good feedback upon activation with a tangible click, the illumination of a red LED and the appearance of the text ‘activated’. The module communicates continuously with the control panel and takes care of passing the status
of the manual alarm and enabling or disabling the further loop. If a short circuit occurs in the loop, only that part of the loop between two isolators will be disabled. The location of the short circuit can be found quickly from the indication on the alarm control panel.
The module has its own encoding number, which can be set quickly from the Laserbox remote control. The module can be tested easily by pressing it in, after which the polycarbonate window can be reset with the key supplied. Available with transparent cover, ideal for use in schools, public areas, food-processing areas, and anywhere there is a chance of accidental activation and a need to reset to monitoring mode.
