1. INTRODUCTION
1.1. THE ASPECT 2010 SERIES
The ASPECT 2010 series of Aspirating Smoke Detectors are highly sensitive for use in computer rooms and other
clean rooms with high demands for early detection of smoke and fire gases. Recommended for use in churches
and office spaces, using capillary sampling points (sniffers) for unobtrusive installation.
Additionally, ELOTEC ASPECT 2010 is built to handle rough conditions with dust, condensation, and ammonium
gases, making it the natural choice for protecting industrial production areas as well as livestock rooms and
greenhouses.
The ASPECT 2010 can be delivered in a number of variations – as a stand-alone system, or for connection to
conventional or addressable fire alarm panels, wired as well as wireless. Several sensor options are also
available.
Each version uses a specially adapted CPU board and firmware for optimal function.
The stand-alone ASPECT is approved as a control panel, and can be supplied with a number of integrated
modules that provide extra functionality.
•GSM transmitter for alarm transmission with voice messages or text (SMS) *
•Network module for remote control or connection to building management systems *
•Control module for approved wireless smoke detectors/alarms and alarm device in the 868 MHz band. *
The ASPECT is manufactured in an anodized aluminum alloy specially developed to maintain its good look even
after extended use in all environments. The top and bottom parts are made of PC/ABS. The closed housing with
overpressure ensures that dust and moisture do not reach the electronics.
The aspirating fan and housing are designed to balance effect and noise, which makes the ASPECT one of the
most silent aspirating smoke detectors available.
•Human speech produces approximately 60 dB, an ASPECT with standard settings produces 55 dB.
•The noise level can be lowered further (5-10 dB) by installing the exhaust kit AU 002.
•Special soundproofing with the fan in “silent mode” can be delivered, lowering the emitted noise all the
way down to 35 dB – the pipeline will naturally have to be shortened correspondingly (see separate pipe
design for dwellings).
A PSU is integrated, but the ASPECT can also communicate with an external 12V or 24 V power supply in cases
where extra capacity is required. (The internal battery must then be removed.)
The ASPECT is also prepared for accepting signals from external filters on the pipeline.
ASPECT has several levels of internal tests:
•Airflow is constantly monitored in order to reveal problems with filters or pipelines.
•Every month, an automatic verification of the flow sensor is performed to ensure that the constant filter
monitor isn’t degraded. By performing this test, the ASPECT achieves a complete test of its internal
processes.
•Sensors run continuous self-diagnosis, and possess an intelligent test system that provides notification
when the sensor needs to be cleaned (CleanMe).
Simple installation and service:
•External flanges ensure that the unit can be installed without touching its internal components, and helps
maintain the integrity of the protective housing.
•The top lid has been designed to allow easy access to the connection terminals in the upper part of the
unit, and can be opened using special tools concealed behind the bottom lid.
•ASPECT allows the door to be opened for inspection and filter replacement for 4.5 minutes with no need
to operate the control panel.
•No manual calibration is required, neither for sensitivity nor filter monitoring. This means the sensitivity
can never be adjusted outside the approved range.
“PipeDraw” planning software provides assurance that EN 54 is followed, and is very easy and efficient in use.
Required components are listed and priced automatically, both for ordering from Elotec and for the offer to the
customer.

1.3. E NVIRONMENTAL ADAPTATION AND SENSITIVITY
When planning an aspirating smoke detector installation, the desired sensitivity class (A/B/C) according to EN
54-20 must be determined. This could be specified by the customer, consultants, authorities, or through
regulations. PipeDraw will indicate if the planned pipeline achieves the required class with the chosen sensor, or if
a different variant must be used.
If smoke or gases are naturally occurring in the secured area, there are several possibilities for adaptation in order
to avoid nuisance alarms.
1. Order Aspect with sensors fit for the environment – three different sensitivity levels per sensor type.
a. Sensor kit can be easily replaced on-site if the wrong choice was made, or the operating
conditions change at a later time.
2. Use the app ASPECT TOOL to set reduced sensitivity for the affected area.
•Medium is used where no special conditions indicate otherwise.
•High may be used to maintain the desired class with long pipelines and many sampling points, primarily in
clean environments where a regular smoke detector can survive.
•Normal is used where other variants are expected to be too sensitive, typically in environments with
extreme amounts of dust or air pollution, as well as certain special applications, like freeze storage.
Remember that by using the companion app, Aspect can be programmed, if the customer wants, to have
higher sensitivity at night than during work hours. See 8.3. Sensitivity, day/night modes, page 35.
Ordering information:
Select one element from each column to find the ordering code for the desired version of Aspect or Sensor Kit.
NB! If ‘Sensitivity’ is not specified, Aspect / Sensor Kit will be delivered with Medium sensitivity.

1.4. I NSTALLATION INSTRUCTIONS
Please read this manual carefully before beginning the installation.
Throughout the manual, there will be paragraphs marked . These are to be considered recommendations or
advice to make the installation easier.
Other paragraphs are marked . These instructions must be followed to ensure that the system will function as
intended.
The symbol may be used to indicate other interesting facts.
In several places in this manual you will find so-called QR codes.
These can be scanned with your smartphone to show items such as
YouTube videos, web pages or apps. If you don’t already have a
barcode scanner installed on your phone, try “QR Droid” for Android
devices, or “QR Reader for iPhone”.
Study the plans made by the project planner, and follow them carefully. The
authorized planner must approve any divergence from the plan. Use cable and
pipe types as prescribed by Elotec. Pipes, bends and fixing sleeves must be
delivered by ELOTEC for the system to be approved. ELOTEC can also supply
a selection of signal cable for wired systems. Other installation materials should
be provided by the electrical contractor.
The connection of mains voltage to the unit must be performed by an authorized electrical contractor, and in
accordance with existing regulations.
Always remember that program settings like the flow window must be adapted to the building mass and
application. See page 48. If unexplained flow faults occur repeatedly, this indicates that the normal air
pressure fluctuates too much to maintain the chosen level of P1 (1-10) and/or time of P6 (1-3).

3. PROCEDURES FOR ALARMS AND FAULTS
3.1. F IRE ALARM
The alarm location is specified through zone indication or device text on the connected fire alarm panel (if any).
A red LED on the ASPECT front indicates the area where smoke has been detected.
Check all rooms that are covered by the indicated pipe area. If no visible smoke can be observed, it is necessary
to inspect the area carefully.
A smoldering fire may not be visible until it bursts into flames at a much later time.
Operation varies, depending on whether the Aspect is connected to a fire alarm panel or not.
Aspect connected to a fire alarm panel:
Alarms are silenced and reset at the control panel – no operation is required at the Aspect
Stand-alone Aspect:
Red button: Deactivate the integrated sounder output.
Green button: Reset the Aspect.
NB! Silencing the attached sounders with the red button will activate the fault output. This is logged as proof of
intentional user operation.
3.2. S ERVICE ALERT
Conditions that require action by the end user or installer are indicated by the generic service LED on the ASPECT
front. To determine the nature of the condition, check the event log.
The purpose of service messages is to make the user aware of internal or external conditions that may affect the
functionality of the aspirating smoke detector system if the condition persists. It is important that the cause is
identified, and any non-conformities are corrected. Please note that certain service messages are normal after
events such as power outages, but may indicate a problem if the message persists after the situation has returned
to normal.
Events are easily displayed in Aspect Tool, but could also be indicated by blinking patterns on the device.
In Aspect Tool: Recommended action for the latest event is displayed.
Operation varies, depending on whether the Aspect is connected to a fire alarm panel or not.
Aspect connected to a fire alarm panel:
Service alerts are silenced and reset at the control panel – no operation is required at the Aspect.
Please note that if the cause of the alert has not been corrected at the device, the alert will return. If an Aspect
loses all power and shuts down, a fault will be displayed at the control panel.
Stand-alone Aspect:
Red button: Deactivate the integrated buzzer.
Green button: Reset the Aspect.
Please note that the fault relay is fail-to-safe, and will trigger if Aspect loses all power.
The event log can be cleared by shorting S100 (Appendix A, item 14 – page 44)
for a moment. This could be done after an annual inspection of the installation.

4. PIPELINE PARTS AND ACCESSORIES
4.1. S AMPLING PIPES
4.1.1. General
Air samples are transported to the detection chamber in ASPECT through pipes. ASPECT systems use pipes with
an outer diameter of 25 mm and an inner diameter of 22 mm.
Original pipes are marked with the Elotec logo to assure that approved pipes are used. Marks are also
applied at one metre intervals to assist in correct placement of sampling holes, as well as a guide line
along the length of the pipe to help avoid twisting the pipeline.
According to VdS/EN54-20, pipe parts must comply with EN61386-1, at least class 1131. Use only
approved original Elotec pipes that fulfil additional demands to rigidity (prevents drooping) and surface
finish. See “IMA 000 109, Pipe layout design and tables”.
Elotec pipes are delivered in 4 m segments that may be cut to length where needed. To ensure clean cuts with no
burrs, use the ELOCUT cutting tool.
Joins are made through special sleeve couplings or bends – no glue is needed, as the sleeves are conical and
supplied with a sealing agent inside.
The entire pipe system is fixed to walls and ceilings using fastening brackets. The standard clamp CL 250 is open,
and the pipes can be pushed straight in. The clamps are spacious enough to allow free movement of the pipes,
which is important where large temperature variations are to be expected. Wire suspension is also an option.
CL 250 CL 255 CL 250 W CL 251 W
Other parts may be used in certain applications.

4.2. AU 002 AIR EXHAUST KIT
4.2.1. Purpose of the exhaust kit
ASPECT can be equipped with an optional air exhaust kit. The AU 002 has three main applications:
1. If ASPECT is mounted in a room with much airborne dust, it is advisable to install the AU 002 with 0,5m lengths
of pipe to lead the exhaust away from the unit. Otherwise, dust may be dragged back into ASPECT because of
turbulence around the exhaust port.
2. If there is a large difference in pressure between the area where air is sampled and the spot where ASPECT is
mounted, the AU 002 must be employed to lead exhaust air back into the protected area in order to negate the
pressure difference. Both areas must draw air from rooms with approximately the same pressure.
3. Sometimes, the ASPECT may be placed in an office, while sampling air from areas with smelly environments.
In this case, the exhaust kit may be used to redirect air to avoid unpleasant smells.
The length of the exhaust pipes must be calculated into the total pipe length. If very long exhaust pipes are
required, it may be necessary to shorten the sampling pipes in order to keep the response time of
ASPECT within the given limits. As a rule of thumb, exhaust pipes shall be no longer than 4m.
The AU 002 can also be fitted to reduce noise from the ASPECT where the sound of the fan is considered
disturbing (like in churches and office environments).
4.2.2. Installing or removing the exhaust kit
The exhaust kit is easily installed without tools. Just set the kit into the slot in the exhaust port as shown in the
picture, and push until it snaps into place.

3. “Key” used for release
The AU 002 accommodates two exhaust pipes, and both must be fitted.
If the kit needs to be removed, one of the “keys” located inside the ASPECT bottom cover may be used to release
the snap as shown in the picture. The AU 002 is then easily pulled free.
