1.4.- External Components
1.4.1.- Conventional Detectors
Smoke Detectors (A30X)
The optical smoke detector (A30XH) is based on the Tyndall effect created in an optical chamber. The
variation of the electrical features in presence of combustion aerosols makes this detector achieve its aim of
detecting fire.
The sensor element is made by an optical chamber with an infrared emitter and receiver. When there is not smoke
the intensity received by the receptor is null due the physical labyrinth between them. In presence of smoke,
infrared reflection in particles males the receiver get a certain light intensity (proportional voltage level according
obscuration level), all this, microprocessor-controlled.
Technical Specifications A30XH
Power Supply 12 – 30V no polarity
Stand by consumption 60 mA (at 18V)
Alarm consumption 40 mA (at 18V)
Activation indicator Doble Red LED
Repeater output Yes
Humidity 20 – 95% HR
Temperature -10º to +40ºC
Sensibility According EN 54-7

6
Heat Detectors (A30XT, A30XV)
Heat detector (DA30XT), gives a temperature alarm produced by a combustion process, independent of
speed, when temperature is 64ºC.
It has a sensor element (thermal function) made with a thermistance (NTC, Negative Temperature Coefficient) and
a comparator circuit with a pre fixed reference value.
Sensor voltage supply and circuit is stabilised, so the detector sensibility is constant in front of variations power
supply. Detector and base are manufactured with ABS plastic thermal resistant.
Rate of rise heat detector (A30XV), has two sensors, one of them gives an alarm according a fast heat
increment produced by a combustion process, and if the speed is not enough fast, then there is the second sensor
that gives the alarm when the temperature is 64ºC. Complying with last EN 54-5.
Sensor voltage supply and circuit is stabilised, so the detector sensibility is constant in front of variations power
supply. Detector and base are manufactured with ABS plastic thermal resistant.

Linear Detector (DL)
Linear Detector is built by an emitter, which projects an infrared beam and a receiver that measures the
beam intensity. Smoke produces a beam intensity reduction that arrives to the receiver.
General Features:
Range: 9 to 100 meters.
Sensibility: The detector has an interrupter with two positions
Position 1: 30% +/- 5% Obscuration total
Position 2: 55% +/- 5% Obscuration total

Once the printer is connected it will be needed to configure the control panel according the communication
parameters specified by the printer manufacturer. The values pre-configured is 9600 bauds, 8 bits for data, 1 bit for
stop and no polarity.
NOTA: It is important to be sure that while the control panel is connected to the printer, it will be necessary to the
communication between repeaters and control panel.
2.4.3.- Repeater.
Connexion will be done with 4 wires. 2 for power supply and 2 for communication trough a RS 485 bus.

Once realised the repeater connection, it will be needed to configure the main control panel according the
number of repeaters (see point 3.2.5.8.) and communication parameters (see point 3.2.3.5.9.). Communication
parameters must be the same with the repeaters and we must be concerned that are used too for the computer. The
pre- configured values are 9600 bauds, 8 bits for data, 1 bit for stop and no polarity.
2.4.4.- Computer.
As we can see in the picture, we can connect a PC to the control panel to configure it with the help of a
programme software (called EASYLondon), with a serial connector. We have to know that when we connect a PC
the printer and repeater exit must be inability.
Communication with computer requires their configuration (see point 3.2.3.5.9.). The pre- configured
values are 9600 bauds, 8 bits for data, 1 bit for stop and no polarity.
If distance is higher than 5 meters, we will have to change the connection to RS485 than RS232 with a maximal
distance of 1,5 km in consequence.
There is an adaptor to change it from RS232 to RS485 needed to connect the computer by a two wires
system to receive and send (half-duplex). The advantage is use the line Tx y Rx without the necessity of a reception
line because this is done directly by the adaptor automatically.
The adaptor has also a protection to assure EMI’s to the communication.
