Optical Beam Smoke Detector Guide Description Ex d Optical Beam Smoke Detector is used for fire detection in explosive atmospheres consists of a standard Controller combined with rugged flameproof dustproof Transmitter Receiver heads The Transmitter and Receiver heads are designed to be mounted within protected hazardous area whilst the Controller is housed outside it installed the Transmitter head projects a modulated infra red beam inherently safe radiation across the protected area to the Receiver head mounted opposite The signal strength is monitored and analysed in the Receiver and should the signal fall below the preset threshold for more than the fire delay selected by the user a fire is signalled to the Controller Statement of Intended Use system is intended for use as a Smoke Detector only in Exd IIC IIIC or lower grade areas must not be used in areas with a greater hazard rating It must be installed and tested by competent personnel in accordance with all regulatory and local codes of practise liability shall be accepted for installations not conforming to this requirement equipment is covered by certificate number Sira 15ATEX1260 and the following apply The equipment may be used with flammable gases and vapours with apparatus group II and temperature class T6 in the ambient temperature range 20 to 55 The equipment is only certified for use in ambient temperatures in the range 20 to 55 should not be used outside this range Installation should be carried out by suitably trained personnel in accordance with the code of practice Inspection of this equipment shall be carried out by suitably trained personnel in accordance the applicable code of practice The equipment does not have any user serviceable parts and must be returned to the for servicing or repair This Installation Guide contains the system Principle of Operation system Specification Precautions Installation Setting Up and Testing Installation diagrams The certification of this equipment relies upon EMH29 Enclosure Component typically Alloy Certificate No TRAC13ATEX0058U from JCE Europe Ltd If the equipment is likely to come into contact with aggressive substances then it is the of the user to take suitable precautions that prevent it from being adversely thus ensuring that the type of protection provided by the equipment is not substances e g acidic liquids or gases that may attack metals or solvents that affect polymeric materials precautions e g regular checks as part of routine inspections or establishing from material data sheets that it is resistant to specific chemicals Label details area into which the parts are to be fitted must be made safe before attempting any work on system It must also be checked thoroughly prior during after commissioning to it cannot compromise the safety of the area in which it is fitted Note that only the and receiver parts may be installed in the hazardous area NOT the controller unit the flamepath of the enclosure is damaged in any way the unit must be returned to the and a new unit purchased General Information clear line of from Receiver Transmitter Unit IMPORTANT NOTE The infrared beam path MUST be kept clear of obstructions at all Failure to comply may result in the system initiating a Fire or Fault signal All installations should comply with local regulations For installations approved to UL 268 refer to NFPA 72 for installation guidance In such it is advised that the maximum distance of Transmitter and Receiver from the must be 10 of the distance between floor and ceiling Ensure a clear line of sight from Receiver to Transmitter Mount on solid surfaces structural wall or girder and ensure fixing is rigid Position beam as high as possible but with a minimum distance of 30cm from to ceiling Mount Receiver and Transmitter directly opposite each other Do NOT position where personnel or objects can enter the beam path Do NOT install the Transmitter or Receiver in environments where condensation or icing are to occur 100m Wiring Diagrams two Receivers onto two zones 1 2 1 COM N C 1 COM N C 2 COM N C 2 COM N C to 36V DC note 1 note 1 1 1 2 2 1 1 connection of two Receivers to one

ALWAYS use a separate 2 core cable for each Receiver head CAUTION For system monitoring Do not use looped wire under any terminals Break wire to provide monitoring of connections Components not supplied End Of Line EOL component supplied by Fire Control Panel manufacturer Fire Resistor After installation check operation of Fire and Fault connection on Fire Panel Apply a voltage of 5V to 40V to RST contact for at least 2 seconds to clear a latched condition For wiring to other types of Fire Control Panel or to wire multiple Controllers onto one Zone to additional installation instructions

initial installation or when adding or removing Receivers seconds will be the number of found enable Receivers Press Any unused Receiver channels are switched off Press re scan if the number is incorrect Select Receiver to be Accessed All Receivers need to be aligned separately Steps 8 and 9 explain how to align individual Receivers LASER Targeting The LASER in the Receiver head is used to align the Receiver with the Transmitter The LASER can be activated using the LASER icon in the ENGINEERING MENU as shown Move the LASER as close to the Transmitter as possible by moving the Receiver bracket The system will signal Fault while in this mode LASER TIMEOUT MIN 1 min mins may be or in 1 min by using RADIATION AVOID EYE EXPOSURE OUTPUT 5mW 3R LASER 630 680 nm Elapsed it is not possible to see the LASER because of the installation environment for example if is high ambient light then align the Receiver by eye so that it is pointing at the Alignment Alignment Mode y
