Every system is controlled and powered individually and operates on a stand-alone basis. Each system comprises a twin-channel audio amplifier, power supply unit, a microphone and speaker for the staff and a microphone and speaker for the customer. The microphone and speaker modules are supplied in various formats to enable the system to be installed in differing locations. The system operates on an “Open Duplex” basis, i.e. microphones and speakers are live simultaneously, similar to a telephone, with no manual or automatic switching of the voice. This means that clipping of speech is not encountered whilst still allowing users to operate the system “Hands-Free”. Sophisticated electronic circuitry in the amplifier and purpose designed speaker and microphone modules ensure that the risk of acoustic coupling or “Feedback” is kept to a minimum. Securicom also offers an induction loop facility which is built into the system for users of hearing aids. SecuriCom is offered either in a system kit format, or as individual modules, thus allowing maximum flexibility to “tailor” systems to individual requirements. 4 SECURICOM SPEECH TRANSFER SYSTEM 1 Part No. STS-K001 SYSTEM COMPONENTS Bridge Bar System Amplifier STS-A20 Power Supply STS-P41 or STS-P42 1a Bridge Bar System with Loop Facility STS-K001-L STS-A30 STS-P43 2 Surface Mounting System Part No. STS-K002 Amplifier STS-A20 Power Supply STS-P41 or STS-P42 2a Surface Mounting System with Loop Facility STS-K002-L STS-A30 STS-P43 3 Part No. STS-K003 Customer Unit STS-B80 Audio Bridge STS-F70 Staff Unit STS-B80 Audio Bridge Induction Loop IL-E97 Induction Loop Sign Staff Unit STS-F70 Staff Unit Customer Unit STS-M54 Microphone and STS-S60 Speaker STS-F70 Staff Unit STS-M54 Microphone and STS-S60 Speaker Induction Loop IL-E97 Induction Loop Sign Staff Unit STS-F70 Staff Unit Customer Unit STS-M56 Microphone and STS-S61 Speaker STS-F70 Staff Unit STS-M56 Microphone and STS-S61 Speaker Induction Loop IL-E97 Induction Loop Sign Flush Mounting System Amplifier STS-A20 Power Supply STS-P41 or STS-P42 3a Flush Mounting System with Loop Facility STS-K003-L STS-A30 STS-P43 4 Staff Unit STS-F70 Staff Unit Staff Unit (common to all systems) The STS-F70 Staff Unit comprises loudspeaker and close talking gooseneck microphone in one discreet unit.

The Amplifier connects on a plug and socket basis to other system components via individual cables. The Amplifier should be mounted on a flat surface within close proximity to the other system components and conveniently to hand for the operator. For example, on the staff side under the desk-top or counter-top would be suitable. Ensure there is also access to the Microphone and Induction Loop gain controls located on the side of the amplifier and also to the rear connection sockets before fixing. Twin flanges each with two screw holes are formed at the top of the amplifier housing.These are used to fix the amplifier under the counter top with small self tapping screws.. The Amplifier housing need not be opened as all connections are external. Siting and Installing Microphones and Speakers Customer Microphones and Loud Speakers may be flush or surface mounted depending on individual requirements. See following pages for fitting instructions. Surface mounted components are best sited at the junction between the counter-top and the glass partition. For best performance, the Microphone should be mounted at least 30 centimetres away from the Loudspeaker. Each component comes with a 3 metre lead and two-way plug. It is advisable to remove the plug before fixing as this enables a neater installation to be achieved using smaller diameter holes through which to feed the cables. However, the cables and plugs must be re-connected correctly or the system will not operate. If in doubt, identify and mark the wires before disconnecting the plug(s). SECURICOM SPEECH TRANSFER SYSTEM Siting and Installing the Staff Unit Amplifier Connections INSTALLATION The STS-F70 Staff Unit is a self standing module for the Staff Side. It should be placed conveniently on the counter top so the cashier can hear the loudspeaker and talk into the gooseneck microphone to the customer. The microphone is of the close talking type so background noise is not picked up. A ‘Mute’ switch is located on the front of the Staff Unit. In the absence of a cable port, a suitably sized hole should be drilled into the counter top at the rear of the Staff Unit to take the reinforced cable. Disconnect the 2 two-way plugs before introducing the cables for a neater installation. Ensure these are re-connected correctly or the system will not operate. 1 2 3 4 5 6 7 LED/Tone (+) LED/Tone (-) Staff Unit Mic 1 (+) Staff Unit Mic 1 (screen) Customer Mic 1 (+) Customer Mic 1 (screen) Staff Mic 2 (+) 8 9 10 11 12 13 14 Staff Mic 2 (screen) Customer Mic 2 (+) Customer Mic 2 (screen) Staff Unit Speaker (+) Staff Unit Speaker (-) Customer Speaker 1 (+) Customer Speaker 1 (-) 15 16 17 18 19 20 Staff Speaker 2 (+) Staff Speaker 2 (-) Customer Speaker 2 (+) Customer Speaker 2 (-) Induction Loop Aerial (+) Induction Loop Aerial (-) Rear of Amplifier showing two-way connections for components Power in Contacta Communication Systems Limited Tel: 0181 858 2123 Induction Cust Staff Loop Spk 2 Spk 2 - + - + - + 20 19 18 17 16 15 Cust Spk 1 - + 14 13 Staff Spk 1 + 12 11 Cust Staff Mic 2 Mic 2 Sc + Sc + 10 9 8 7 Cust Staff Mic 1 Mic 1 LED Tone Sc + Sc + + 6 5 4 3 2 1 Connection plugs - + Connection to Induction Loop Aerial Connecting Components to the Amplifier Controls - + - Optional connections to second loudspeakers + - + - + Connect Connect to Staff to Unit customer loud speaker Sc + Sc Optional connections to second microphones + Sc + Sc + Connect Connect to to Staff customer Unit microphone - + Connection to LED or tone signal (optional) Each component (Microphone, Loudspeaker, Staff Unit or Induction Loop) comes fitted with two-way connection plug(s) which locate into the appropriate socket(s) at the rear of the Amplifier. The plugs connect to the cables by screw terminal connections so cables can be removed and fed through small, neat apertures for an unobtrusive, discrete installation. However, the cables and plugs must be re-connected correctly or the system will not operate. If in doubt, mark the wires before disconnecting the plug(s). If there is a suitable cable port on the cashiers side, the Staff Unit cables can be diverted through this without the need to remove and re-connect the 2 two-way plugs. Controls are provided on the front of the Amplifier. The latching push switch marked ‘power’ switches the unit on or off, a red LED indicates when the unit is on. Two rotary volume controls marked ‘customer’ and ‘staff’ adjust output from the loudspeakers. The volume of the system may be adjusted by turning the rotary volume controls clockwise (to increase the level of sound) or anticlockwise (to decrease the level of sound).

STAFF OMER CUST 20/30 STS-A Induction Loop Facility Adjusting the Induction loop facility If the SecuriCom System has been supplied with optional Induction Loop Facility, the package will contain an STS A30 audio amplifier, a P43 Power Supply Unit, a suitable Induction Loop Aerial, (either IL-E93, IL-E94 or IL-E95) and a self adhesive yellow induction loop sign (IL-E97). The principle of the system is to transmit sound via an electro-magnetic field which is picked up and amplified by a telecoil fitted inside customers’ hearing aids. Correct positioning of the Induction Loop Aerial is critical to ensure the loop performs to its full potential. It should be fixed under the desk-top or counter centrally so customers wearing hearing aids receive the signal. In the case of the IL-E94 (Loop Pad Aerial), for best results, this can be folded so that half is mounted horizontally under the counter and the other half mounted vertically, facing the customer. Make sure that the Induction Loop self adhesive yellow sticker is displayed in a prominent position. The Induction Loop Aerial connects to terminals 19 and 20 on the Amplifier using the appropriate plug and socket. The control for adjusting the Induction Loop gain is located on the side of the amplifier and output may be adjusted by using the trim tool and an induction loop tester. Turn the gain potentiometer clockwise (to increase gain) or anticlockwise (to decrease gain). ta contac power R CUSTOME STS-A STAFF 20/30 Fix Induction Loop pad to underside of counter in horizontal and vertical plane 12 SECURICOM SPEECH TRANSFER SYSTEM Bridge Bar System STS-K001 STS-B80 Audio Bridge STS-F70 Combined Staff Unit FITTING INSTRUCTIONS Glass security screen Knurled point cup screws for fixing bridge bar Drill suitable hole in counter for cables Surface mounted Bridge Bar pod (left hand position accommodates all cabling) Cash Cash Tray Surface mounted Bridge Bar pod (right hand) 625 mm wide Drill twin pilot holes for fixing screws Figure 1 Bridge Bar with Gooseneck Microphone Glass security screen Tighten knurled point cup screws to fix bridge bar at both ends All cables exit left through counter top Use small pipe cutter if cutting bridge bar to length to avoid damage to internal cables Cash Tray Figure 2 Glass security screen Connect first loudspeaker and fit to pod Cash Tray Connect second loudspeaker and fit to pod Figure 3 Use existing cable port or drill suitable hole through counter top to feed cable from Staff Unit STS-F70 Staff Unit Microphone Surface mounted Bridge Bar system utilising twin loud speakers and gooseneck microphone Glass security screen Loudspeaker Cash Tray Retaining m/screw Loudspeaker Customer side Figure 4 13 SECURICOM SPEECH TRANSFER SYSTEM FITTING INSTRUCTIONS Surface Mounting STS-K002 STS-M54 Microphone STS-S60 Speaker STS-F70 Combined Staff Unit Glass security screen Surface mounted speaker or microphone pod Drill suitable hole in counter for cable Figure 1 Drill twin pilot holes for fixing screws Cash Tray Glass security screen Fix pod to counter top with 2 (No) self tapping screws Cash Tray Figure 2 Run cables from speaker or microphone through counter top and fit unit to pod.

It communicates visually and audibly with your customers, directing them to the next available position in an orderly manner with no confusion. As a result, quality of service is improved and staff can concentrate solely on their immediate customer’s requirements. Q-Control is particularly effective where financial and confidential matters are being dealt with. Research has indicated that customers are happier and more relaxed with an efficient queue management system. It’s fairer because they can be served in the correct order, there’s no jostling and the next customer is not ‘breathing down their neck’, – a safety factor that is particularly appreciated when money is changing hands. Contacta Q-Control system in use at Tottenham Hotspur’s Ticket Office At the centre of the system, and usually located in a prominent position at the head of the queue, is the Main Display Board. This provides audible and visual information concerning the queue direction. The visual information is shown on three LED panels. The Central Control Module contains all central system circuitry and is linked to the other system components by the system cable network. Each staff position is identified by an LED display denoting the counter position number. In addition each member of the staff has a switch which can be depressed when the position becomes free. The Q-Control system interfaces with other Contacta equipment such as the SecuriCom Speech Transfer System and InfoLoop Induction Loop system to provide the optimum in customer care at service and cashier positions. Contacta InfoLoop The InfoLoop Induction Loop System from Contacta is a loop based voice amplification Hearing Aid Induction Loop Systems system to assist customers who use hearing aids. By simply switching their aid over to the “T” or “Telecoil” position, their aid reduces air transmitted sound signals and receives speech via the Induction Loop and the Telecoil located within the hearing aid. InfoLoop gives clear hearing and understanding for those with hearing disabilities. It is designed for ticket offices, bank and building society counters, bureaux de change and interview and meeting rooms. InfoLoop is the perfect answer for high background noise areas where confidential discussions take place or when clear speech is restricted by glass security screens; traditionally “difficult” areas for hearing aid users. Each system is controlled and powered individually and operates on a stand-alone basis The system essentially comprises a microphone, an amplifier which drives the induction loop and a power supply unit. Various types of microphones and loop aerials are available to meet the precise, acoustic and logistic needs of each location. In addition, a portable, self powered Induction Loop System is available for more flexible use. 19 L I M I C O M M U N I C AT I O N S Y S T E M S T • D SECURITY SOLUTIONS Sales Office: 50 Churchill Square, King’s Hill, West Malling, Kent ME19 4YU.
