3.3 Function

The linear smoke detector smoke detector consists of a transmitter and a receiver and works according to the principle of light attenuation by smoke. The transmitter transmits to the reflector a highly focused, pulse-shaped infrared ray. If no smoke is present, a large part of the infrared ray reaches the reflector and is returned to the receiver. The incoming light generates an electric signal on the receiver's photo diode.

Fire Safety 2012-09-07

Page 21

Structure and function

Function

When smoke is present, part of the infrared ray is absorbed when it encounters the smoke particles, while another part is scattered by smoke particles. The rest reaches the reflector and is returned to the receiver. The infrared ray is attenuated further. Only a small part of the infrared ray initially transmitted reaches the receiver, and the electrical signal becomes weaker.

Function of the linear smoke detector with smoke

1 Absorption 4 Smoke particle

2 Scattering 5 Infrared ray

3 Attenuated infrared ray

The linear smoke detector measures the distance, which enables an exact alignment of the smoke detector to the reflector when the detector is commissioned.

Due to distance measuring, the smoke detector recognizes when the measuring section is crossed by a reflecting object. In this case, the smoke detector sends a fault signal to the control panel.

3.3.1 Infrared ray

Setup of the infrared ray

The infrared ray is scattered, giving it a conical shape. The radiation energy decreases outwards. The infrared ray is divided into the following three ranges:

 Effective range (1): The effective range is the connection between the

transmitter, reflector and receiver.

 Core range (2): In the core, enough radiation energy is present to operate the

system.

 Scattering range (3): The radiation energy in the scattering range is insufficient

and does not ensure the functionality of the system.

Example of calculating the diameter of the core range depending on the detection distance:

Known: Detection distance l = 100 m

Wanted: Diameter d of the core range

Adjustment options for the infrared ray

The infrared ray can be adjusted horizontally by a maximum of 10° in either direction and vertically by a maximum of 5° in either direction. This adjustment range can be used for an optimum positioning of the devices. In the case of detection distances greater than 50 m, position the detector and reflector as close to opposite one another as possible. This makes adjustment easier.

One turn of the knurled screw moves the infrared ray by approx. 0.8 m per 100 m distance.

3.3.2 Reflectors

Retro-reflectors reflect rays of light that reach them in parallel. The reflector does not necessarily have to be installed at a right angle to the ray of light. Vibrations and distortions on the installation surface do not interfere with this. Interfering light is also reflected in parallel and does not therefore reach the receiver.

The reflectors must be installed at an maximum inclination angle of 20° in all directions.

Reflector for long distance (prism) DLR1191

The reflector for long distance consists of a prism and a housing. The retroreflecting prism has the shape of an even pyramid, the lateral surfaces of which are made up from isosceles, right-angled triangles. Light rays coming in through the base surface are completely reflected thrice by the lateral surfaces and are than scattered back through the base.

The reflector for long distance is fitted with a heating unit and can therefore be used in environments with a danger of moisture condensation. The heating unit must be connected to a 24 V supply.

Reflector for middle distance (foil) DLR1192 and reflector for short distance (foil) DLR1193

The reflectors for middle distance and for short distance consist of a foil with microprismatic elements, which are formed in a transparent, synthetic resin, sealed and mounted on a plastic base. The foil has the same principal effect as the prism.

3.3.5 Diagnosis levels

Information displayed on the detector exchanger and tester

For the most part, the linear smoke detector monitors its functionality autonomously.

The following diagnosis levels are derived from the different control measurements:

 Normal

 Observe information

 Fault

For details, see table below.

When a fatal error (one which impairs the detector's function) occurs, a fault message is signaled. To correct the cause of the fault, additional information is available in the detector. This can be displayed by the detector exchanger and tester FDUD292 or the intelligent detector tester FDUD293, for example.

'no deviation' Normal, no fault is present

The detector is fully functional

'maybe excha.' 1 Observe information

3.3.6 Signal processing

The signal processing of the detector efficiently distinguishes between fire events and deceptive phenomena. The basis for reaching a danger level is not only given by measurements below a certain response threshold; moreover, the smoke density progression is observed over a longer period of time and evaluated with ASAtechnology (ASA = Advanced Signal Analysis). The detector processes the signal according to internal diagnoses and reports the result to the control panel.

Correction value

The compensation value is the reference value for the current signal. All response thresholds and evaluations are based on the current compensation value.

The first compensation value is defined during initialization. The compensation value is updated approximately every 60 minutes to compensate for any slow signal drifting. This drift may be caused by dirt on the detector, for example.

The current compensation value is saved in a non-volatile memory every 23 hours and is not lost in a power cut.

The compensation value can be a minimum of 50 % of the compensation value during initialization.

Standardized signal value

The standardized signal value is the signal value (as a percentage) of the current compensation value. If the signal value is the same as the compensation value, the standardized signal value is 100 %. The standardized signal value is displayed on the adjustment device.

Response threshold

The response threshold corresponds to the standardized signal value for danger level 3. When the signal drops below the response threshold, algorithms are activated that trigger an alarm after a certain amount of time. Depending on the sensitivity level of the parameter set selected, the response threshold may be higher or lower:

 Very sensitive: Response threshold is 30 % below the compensation value.

 Sensitive: Response threshold is 50 % below the compensation value.

 Standard: Response threshold is 65 % below the compensation value.

Examples of fields of application of the linear smoke detector

4.2 General planning information

 Between the detector and the reflector therer must be permanent, undisturbed

visual contact.

– The infrared ray must not be interrupted by moving objects, e.g. cranes,

ladders, transportable objects, cobwebs.

– Vision impaired by dust, vapor or smoke generated as a result of operation

may impair the system.

 The detector's installation location must be absolutely statically stable, as the

admissible deviation of the infrared ray is max. 0.1°. Examples:

– Concrete and brick walls are suitable.

– Wood and steel girder constructions are unsuitable, as temperature and

humidity fluctuations, wind or snow pressure influence on such constructions.

 The detector and reflector must be securely installed on the installation surface.

 In the case of detection distances greater than 50 m, position the detector and

reflector as close to opposite one another as possible. This makes adjustment easier.

 Position the detector near the ceiling, as the smoke is generally only sufficiently

think to trigger an alarm in the mushroom cloud.

 Avoid bringing the detector into direct contact with sunlight, halogen lights etc.

Planning

Planning in rooms with flat ceilings

 The infrared ray must be at least 30 cm away from ceilings, walls, fittings and

goods in stock to avoid unwanted reflections. You can use the adjustment device to check for unwanted reflections. Instructions for this can be found in the chapter 'Testing detectors [➙ 77]', in the 'Testing detection distance' section. If the standardi

zed signal value is greater than 5 %, you must increase

the distance by the infrared ray.

 Ensure there is sufficient space around the detector such that the infrared ray's

entire adjustment range can be used.

 If you use covers or enclosures for the detector, you must ensure sufficient

space around the detector such that e.g. the following work can be carried out efficiently and without hindrance:

– Connect the adjustment device

– Set the detector optics

– Mount hood

 After commissioning for the first time, the service personnel must be able to

access the detector safely and with ease, e.g. for maintenance and adjustment work.

Type and number of reflectors depending on the detection distance

If you are using more than one reflector, always position them close together and in a square shape. The detection distance details are guidelines. They depend on detector and reflector tolerances and may vary by a few meters. It is important that a sufficiently high signal intensity is reached.

If there is a danger of moisture condensation, always use the reflector for long distance and the built-in heating unit, even for short distances. You may not use the reflectors for middle distance and short distance if there is a danger of moisture condensation.

4.5.1 Measures for long distances

Long distances can be split into smaller ones for monitoring. Detectors positioned opposite one another can however have a negative influence on one another. In such a position, install a sufficiently large plate between the reflectors, such that it is not possible for detectors to influence those opposite them.

Planning

Subdivision of a longer distance

To check whether two detectors are influencing one another, proceed as follows:

1. Commission the first detector and use the adjustment device to measure the

standardized signal value.

2. Commission the second detector.

3. Use the adjustment device to once again measure the standardized signal

value of the first detector.

- If the standardized signal value has not changed since the first measurement, the two detectors are not influencing one another.

- If the standardized signal value has changed since the first measurement, the two detectors are influencing one another. Install a larger plate between the reflectors or take other suitable measures.

4. Completely cover the reflector and for each detector use the adjustment device to measure the standardized signal value. Measure the signal value once when the the detector opposite is switched on and once when it is switched off. The two signal values measured must not differ.

4.5.2 Measures for short distances

In the case of a short detection distance between 5 and 10 m, you must also use a short distance filter. The following filters are available:

In order that the detector can detect smoke, the infrared ray must be positioned immediately below the heat accumulation. Detectors and reflectors must therefore be positioned at an ever-greater distance from the ceiling as the room height increases. The steeper the angle of a gable roof, the greater the distance must be between gable and infrared ray positioned in gable.

4.9 Installation surface

The detector must be installed on a stable and vibration-free surface. Remember that large fluctuations in temperature (e.g. between day and night) can cause slight deformations to iron girders etc. If the detector is installed on an unstable surface, the infrared ray may not reach the reflector and therefore causes an alarm or fault. The following are examples of unstable installation locations:

 Walls of non-insulated rooms with steel constructions. These move due to the

lengthwise expansion of steel.

 Bricked walls, on which a steel roof construction is placed.

In such cases, the detector must be installed on a stable surface, while the reflector can be installed on the unstable wall.

Example

The example below illustrates how the infrared ray is deflected by the influence of heat on a hall roof's steel construction.

4.11 Arrangement with girders

The detector can be positioned in the ceiling panel between the girders or below the girders.

Girders include building elements (e.g. air conditioning ducts) installed at a distance of at maximum 15 cm below the ceiling.

Position in the ceiling panel between girders

The detector must be positioned in the ceiling panel between the girders if the height of the girders is more than 20 % of the total room height. In this case, the girders are considered as partition elements, and each ceiling panel must be considered as a separate room.

Detection through glass panes is only possible under certain circumstances. Please observe the following points:

 Glass panes must be smooth, clear, and stably fitted.

 A maximum of two glass panes, each max. 5 mm thick, may be penetrated. It is

however better to only penetrate one glass pane.

 The detection distance is reduced by 20 m per glass pane.

 Detection is faultless when the standardized signal value is less than 5 % when

the reflector is covered.

 Glass panes may never be at a right angle to the infrared ray (see example

below).

 Glass panes must never be installed at an angle to the infrared ray, in which

the glass pane acts as a mirror and can reflect the infrared ray to the receiver (impact angle = angle of reflection).

Mounting reflectors on glass plates

When reflectors are installed on glass panes, there is danger of the glass panes, not the reflector, reflecting the infrared ray. This may even occur after commissioning, when the glass plate is slightly shifted. However, this is not the case when the infrared ray does not hit the glass pane at a right angle, but at a slight angle.

Recommendation: The infrared ray should reach the reflector at an angle of 5 to 10° to avoid unwanted reflection.

4.13 Measures against moisture condensation

Moisture condensation on the detector or reflector can cause faults and false alarms. Moisture condensation can occur e.g. when the detector or reflector is installed in a room with cool outer walls, where high air humidity and rapid temperature increases can be expected as a result of sunshine on a non-insulated roof, for example.

 Use the detector heating unit DLH1191A for the linear smoke detector if there

is a danger of moisture condensation.

 If there is a danger of moisture condensation, always use the reflector for long

distance and the built-in heating unit, even for short distances. You may not use the reflectors for middle distance and short distance if there is a danger of moisture condensation.

4.15 Determine parameter set

A parameter set can be used to set the linear smoke detector perfectly to the ambient features.

Two types of parameter set, each with three sensitivity levels, exist. The parameter sets with open line and with British Standard Alarm differ in the way the smoke detector responds to a signal interruption.

Parameter sets with interruption Parameter sets with British Standard Alarm

Planning

In the case of a signal interruption (signal less than 10 % of the compensation value), the 'Signal interruption' fault occurs. An alarm is suppressed.

In the case of a distance interruption (signal less than 40 % of the compensation value), the 'Distance interruption' fault occurs. An alarm is suppressed.

After canceling the fault, any possible alarm is delayed for 40 s.

With distances of less than 7 m, the distance is not evaluated.

The table below shows the parameter sets in three sensitivity levels and sample applications of the parameter sets.

Standard Alarm

In case of a signal interruption (signal below alarm threshold), an alarm is actuated.

In the case of a distance interruption (distance measuring less than 40 % of the initialization distance), the 'Distance interruption' fault occurs. An alarm is suppressed. When the signal drops below the alarm threshold during the fault, an alarm is actuated after 40 s.

With distances of less than 7 m, the distance is not evaluated.

Switching detector over to collective operation

5.1 Switching detector over to collective operation

When supplied, the detector is set for operation on an FDnet/C-NET detector line. When operating a collective detector line, the control panel normally switches the detector to collective operation automatically.

Some collective control panels do not however automatically switch from FDnet/CNET operation to collective operation. In these cases, you must switch the detector over manually. If you are not certain whether the detector is switched over automatically, switch it manually to collective operation before installing.

The detector always switches automatically from collective operation to FDnet/CNET operation.

Procedure

Note the positive and negative poles.

 The detector base must not be connected to the detector line.

1. Connect the detector base to a DC 12 V to 28 V source of DC voltage, e.g. a battery, according to the connection diagram shown below. Use a screwdriver to remove the load from the spring clip so you can slide in the wire.

2. Insert the detector unit into the detector base.

3. Wait around 15 seconds and then remove the detector unit and source of DC voltage.

 The detector is switched over to collective operation and can be connected to a

collective detector line.

Checking the standardized signal value and detection distance

Checking steps Criteria Measures

Maintenance / Repair

Performance check

Use the adjustment device to check the standardized signal value and the detection distance.

Compare the values with those of the last commissioning session. Enter the values on the label in the hood and in the system documentation.

Cover the reflector and use the adjustment device to check the standardized signal value.

 The standardized signal value

must be 100 % ±3 %.

 The distance indication must

not deviate by more than ±10 % from the effective detection distance.

The signal value on the adjustment device must not deviate by more than ±10 % from the value entered under 'Signal value' on the label.

The standardized signal value on the adjustment device must not deviate by more than ±3 % from the value entered under 'Deviate signal' on the label.

The distance indication on the adjustment device must not deviate by more than ±5 % from the value entered under 'Distance' on the label.

The standardized signal value must be less than 5 %.

 Repeat initialization.  Check the coverage area for changes, e.g.

obstacles, reflections, structural adaptations.

 Check the signal value during initialization.

 Check the coverage area for changes.  Ensure that the detector and reflector are

secure.

 Check the coverage area for short-term

changes, e.g. dirt, smoke, vapor, insecure installation or installation surface. It is possible that the compensation value has not yet been updated.

 Check the coverage area for changes, e.g.

obstacles, reflections, structural adaptations.

 Check the coverage area for extraneous

light.

 Remove or cover reflecting objects.  If necessary use the extraneous light filter

DLF1191-AC.

 Check whether the detector is aligned

correctly.
