- Page 2 The suffix X at the end of the certificate numbers indicates that there are special clauses added for safe use of these units. 3.0 Types of Approval and Standards Applied The Klaxon IS Sounder product has been approved to the following standards: IEC 60079-0:2011 / EN 60079-0:2012 + A11:2013 IEC 60079-11:2011 / EN 60079-11:2012 EN 54-3:2001+A1:2002+A2:2006 www.acornfiresecurity.com...
- Page 3 4.0 Zones, Gas Groups and Temperature Classifications The Klaxon Intrinsically Safe Sounder-Beacon Range is certified to the following: Ex ia IIC T5 Ga, Ex ia IIIC T100C Da, Ex ia I Ma. This means that the units can be installed in locations with the following condi-...
- Page 4 www.acornfiresecurity.com 5.0 Installation The TimeSaver base enables quick and easy installation of these units with no extra cabling to be made to the head of the unit. Connections are made to the base during the initial wiring phase which results in a faster and more reliable installation.
- Page 5 www.acornfiresecurity.com • The location of the Sounder-Beacon should be chosen with due regard to the area over which the signalling device must be audible/visable. • These units are suitable for wall or ceiling mount only. • Environmental exposure conditions during installation should be dry. Moist or wet conditions should be avoided.

Each unit must be powered via an approved Zener Barrier or Galvanic Isolator with entity perameters that do no exceed: Uo:28v, Io: 93mA, Po:660mW, Ci:0, Li:0 The combined Sounder Beacon can be operated in 3 ways, Sounder only,...
- Page 7 www.acornfiresecurity.com Connection into the unit must be via a suitably rated Zener Barrier/Galvanic Isolator, the connections for combined operation are below. Independant Sounder/Beacon Alarm When the Sounder and Beacon are required to operate independantly, this is done by switching the negative connections as shown in the table on page 6. There are a number of ways for this to be accomplished through the suitable barriers, a number of methods are shown below: For this application, a barrier with 2 Diode return paths is required as shown in...
- Page 8 www.acornfiresecurity.com Galvanic Isolator The TCC-00XX Intrinsically Safe Sounder Beacon Range is compatible for use with suitably rated Galvanic Isolators. The Glavanic Isolators have the advan- tage of not requiring an isolated high integrity earth to be installed to connect the Zener Barriers. These Isolators are often more expensive per unit but may reduce installation costs as the earth is not required.
- Page 9 www.acornfiresecurity.com End of line monitoring is applicable to the Sounder Product. For this to func- tion correctly, the resistor must be connected between the IN+ terminal and the Sounder Negative Supply. A suitable Zener Barrier which can allow reverse polarity monitoring to take place and a fire panel compatible with Intrinsically Safe products must also be used.
- Page 10 7.0 Maintenance Little or no maintenance is required during the normal working life of the product. The Klaxon Intrinsically Safe enclosures are resistant to most acids, alkalis and chemicals and have been designed to withstand severe weather conditions. However it is suggested that continuous supervision and periodic inspections may be required in relation to the requirements of the installation as per IEC 60079-17.
- Page 11 www.acornfiresecurity.com As previously stated in the installations sheet, the Intrinsically Safe Sounder Beacon Range must be powered via a suitable Zener Barrier or Galvanic Isolator whose characteristics do not exceed: Uo:28v, Io: 93mA, Po:660mW The value for Uo must be between 16v and 28v, and Io should not be below 50mA.
