2 Introduction The Audio Verification Unit (PR107) is designed to enhance security alarm systems by adding audio verification without changing the existing control panel. It has been designed to be used with either standard digital communicators ,Red care, Modems or as a standalone device. Features Eight microphone inputs each capable of using 4 microphones. Audio expander (sold separately) providing up to 128 microphone capability Audio storage circuit capable of storing up to 30 seconds of audio.
3 SYSTEM OVERVIEW Before the operation of the unit is described, it is essential to understand three fundamental features. Audio Verification. Audio verification is achieved by connecting microphones, fitted throughout a protected premises, to the AV Unit.
4 Connection Details Control Inputs SET The SET terminal is used to start the recording cycle, when input is activated the recording starts ( Option Switch 2 must be “ON”) AL The Alarm trigger is used to activate the system. C/S The Communication Successful input is used for confirmation that the alarm signalling equipment has communicated its’ alarm signals successfully. (A C/S output is available from most “Digicoms” ) Note : The AV60 will only answer an incoming call when the AL input is active.
5 System Features Explained Audio Recording. The A.V Unit can Record 30 seconds of audio received from all microphone inputs. When an alarm is triggered the A.V unit will store half the time programmed before the alarm and half the time programmed after the alarm, IE 15 seconds pre and 15 seconds post alarm. (this facility will only function if the AV unit is programmed to record after the system is set. The recorded audio can be replayed by the central station during alarm condition.
6 Broadcast An output is provided to allow the central station to directly talk to the site through loud speakers (AV60 Broadcast speaker system). Part Set The 4 part set inputs are used to enable 4 pairs of microphone inputs, The polarity and control of these inputs is programmed by SW1 switch 1 (see page 8) This facility can be used to provide a system with area setting facilities or, if used in a domestic system, a night set facility.
7 Programming The AV unit can be programmed on site by using the option switches fitted to the unit.
Switch 3 8 Selects how the Relay is to be controlled ON Controlled remotely by the monitoring station using DTMF Tones OFF Automatically switches when AV60 answers incoming call (refer to page 6) Switch 4 Selects the use of BT Star Services. (refer to page 6) ON Star Services not in use OFF Star Services enabled Switch 5 Selects the audio available to the monitoring station immediately the AV60 answers following their Dial up and “listen in” to site. ON All channels open and listening to Live Audio.
9 MICROPHONE UNIT (PR086) Detect LED : Live LED : Features This led illuminates as the unit responds to audio detection (primarily used for commissioning) This led is illuminated when the AV Unit is in "listen in" mode and cannot be disabled by the user. 0V, Out, 12V : Connections connected to 0V, Audio in and 12V of Audio channel of AV Unit Active Input : connected to "SW WHEN LIVE" terminals of AV Unit.

11 SYSTEM REQUIREMENTS Always refer to reference manual of host equipment before connection The Audio Verification unit is primarily controlled by the security system. i.e unless the system is in an alarm condition, no "listen in" facility can be initiated. Host equipment Please ensure that the host equipment (i.
12 Suitability for use The AV Unit is suitable for household, office and similar indoor use when connected to direct exchange lines using Loop-disconnect or Multi-frequency dialling. It is not suitable : (i) as an extension to a payphone (ii) for use on shared services or a leased line system. Note : Apparatus is treated as connected directly to the PSTN line if it is connected to the PSTN via a Relevant Branch System (RBS). For definition of an RBS refer to BS6789 Section 6.1, Clause 2.
13 INSTALLATION REQUIREMENTS In order to maintain the independent approval of this unit, it must be installed such that clearance and creepage distances shown in the table below are maintained between The unit and any other assemblies that either use or generate a voltage shown.
