User manual ADVANTOR AV60 AUDIO VERIFICATION UNIT

[. . . ] Each central station will have there own particular procedures for dealing with audio verification and you should consult your central station for details. The AV unit has the ability to comply with every existing procedure, you will have to program the unit in specific ways to comply with the requirements of some central stations (see application notes) 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") The Alarm trigger is used to activate the system. 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" ) AL C/S Note : The AV60 will only answer an incoming call when the AL input is active. [. . . ] Relay The relay can be either controlled from the Central station or it can be programmed to switch when the AV unit receives an incoming call, this can be used to silence local sounders. 1: Auto switch relay after answering a call (auto switch back after shut down) 2: Pulse for approx. two seconds (central station control) 3: Switch ON ( Central station control). 4: Switch OFF (Central station control) Switched outputs The switched O/P's operate in the same way as the relay (except auto switching). two seconds (central station control) 2: Switch ON ( Central station control). 3: Switch OFF (Central station control) Talkback With the AV60 Two way talk is possible (talkback). To use this facility refer to the instructions provided with the AV60 Talk back unit. 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. Site Announcement The AV unit has the facility to record on site an announcement which is then replayed when the central station dial in to the site. This acts as a conformation that they are listening to the correct site. Function Announcement The A. V unit has pre-recorded function announcements, these provide verbal conformation to the central station operators that the function they have selected is now in operation. when the central station selects replay recorded audio, the message "STORED" will be played before the actual recorded audio is played. This will provide evidence that the central station carried out a particular function as all calls are recorded at the central station. Site Access Pass Code The AV Unit has the ability to use a pass code which must be entered by the central station before they can gain access to the audio on site. The pass code function is normally disabled to use this facility refer to "programming" on page 9. The pass code will be retained even if the power is removed from the AV unit and can only be programmed or changed "on site" LED Indicators There are 4 LED's to provide information regarding the status of the AV60 Unit during the various operating sequences. Indicates the unit is "on Line" or in Commission mode Indicates that the first control tone has been accepted and is now waiting for the second tone. 7 Programming The AV unit can be programmed on site by using the option switches fitted to the unit. SW1 No 1 2 3 4 5 6 7 8 Option Input Type Recording Relay Star Services Audio sequence C/S Not used Test Mode ON Positive Start on SET Remotely Controlled Not in use "Live" audio on answer Not Used Off OFF Negative Start on ALARM Auto switched on "Answer" Active "Stored" audio on answer Active Test mode Since the outputs available from Alarm Control Panels are varied, the AV60 can be programmed for control by either positive or negative voltages. The "Jumper link" is used to select either pull up (to 12v) or pull down (to Gnd) Control inputs Switch 1 Provides the option to activate the Control Inputs by applying +ve or ­ve voltages. Control Panel Outputs Switched to +12V on activation Normally +12v, removed on activation Switched to 0V on activation Normally 0V, removed on activation Note : Switch 2 ON OFF Switch 1 ON OFF OFF ON Jumper link Pull Down Pull Down Pull Up Pull Up Any unused Part Set Inputs must be linked to +12v Any unused Part Set inputs must be linked to 0V Selects the recording Start Time Records all the time while the system is SET Starts recording only when an alarm as activated. 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) Selects the use of BT Star Services. (refer to page 6) ON Star Services not in use OFF Star Services enabled Selects the audio available to the monitoring station immediately the AV60 answers following their Dial up and "listen in" to site. Commissioning Switch 4 Switch 5 Switch 6 Switch 7 Switch 8 Note : Unit must not have AL or Set inputs activated (i. e. [. . . ] 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. 4 Note : The AV Unit is not intended to be used to answer naive callers. A naive caller is a caller with no special knowledge of the characteristics of the autoanswering system who would not have reason to expect an answer to be unusually delayed or who would be uncertain how to act without guidance from the answering system. (Refer to BS6789 Section 3. 2, Clause 2. 6) CONNECTION REQUIREMENTS Safety All terminal connections are SELV (Safety extra-low votage) type circuits and only SELV type circuits must be connected to these ports (for definition refer to EN60950 : 1992 clause 2. 3) Supply The AV Unit requires a Fused (1A) nominal 12V d. c.
