1 Description

The AEL02 Active End of Line Device enables ASL amplifier systems to monitor either single or dual loudspeaker circuits without the need for DC blocking capacitors in the loudspeakers. This makes it ideal for retrofitting into existing installations where it is not possible to modify the installed loudspeakers.

The loudspeaker monitoring using the AEL02 is fully compliant with BS EN 5839 Pt 8.

The AEL02 operates by utilising 30 Hz and 20 kHz surveillance tones that are output by the iPAM400 Intelligent Public Address Amplifier Mainframe, or by LSDDC or LSIDC amplifier interfaces in other types of ASL amplifier systems1,2. The AEL02 derives power from the 20 kHz surveillance tone, and monitors the line integrity by detecting the 30 Hz surveillance tone. On detection of the 30 Hz surveillance tone, the unit introduces a periodic signal current which the standard circuit within the ASL amplifier systems unit can detect. If the 30 Hz tone is lost due to open or short circuit, then this periodic signal disappears and a line fault is reported. The earth monitoring circuit within the ASL amplifier system can still detect ‘real’ earth faults.

The AEL02 is fitted at the end on the loudspeaker circuit across the 100 V line, and with an additional connection to earth. This earth is ideally via the loudspeaker drain wire provided that continuity is maintained back to the rack (Figure 1), or can be a local earth3 (Figure 2).

Two AEL02 units may coexist on an amplifier which enables dual A&B loudspeaker circuit monitoring. In this application each AEL02 is set to act for either the A or B circuit by an internal link in order to separately signal to a single LSDDC interface card.

The diagrams in Figure 1 and Figure 2 show the AEL02 in general context in relation to other system components. They also illustrate the possible connections to earth.

Field connections are provided by an internal 3-way ceramic block terminal which together with a thermal fuse prevents any short circuits on the loudspeaker line in the event of extreme temperatures. The unit is housed in an IP65 rated die-cast aluminium enclosure.

1 LSDDC Dual DC Line Surveillance Interface card enables single and dual A/B loudspeaker circuit monitoring. LSIDC Line Sensing Direct Current Interface card enables single loudspeaker circuit monitoring. 2 AEL02 is only supported by recent versions of Router software. Please refer to ASL for details. 3 Differential voltages between earth locations may affect performance. ASL recommends that a site survey be carried out prior to

installation using the local earth method.

4. You will need Config Tool V1.8.3.488 or later in order to be able to configure the surveillance tones required by the AEL Active End of Line Device.



5.1 Configuring the Router Outputs

With the AEL02 the audio path through the rack wiring to each amplifier, and through the amplifiers, is monitored by means of a low frequency surveillance tone with nominal frequency of 30 Hz. Additionally the AEL02 requires the presence of a 20 kHz tone in order to derive the power required by its own internal circuits.

The Router generates both surveillance tones. Each surveillance tone is configurable in terms of level and pulse width. Additionally each Router audio output needs to be configured to have these surveillance tones superimposed as required.

Configuring the Surveillance Tone Settings at the Router Outputs:

1. Configure the surveillance tone overall settings. These settings apply to all Router outputs.

a. Set the 30 Hz surveillance tone overall level in order to ensure a nominal 1.5 V RMS tone.

Menu: Configuration System Router Outputs All Outputs Surv-tone 30Hz(db)=–<db>

Possible values: –63 dB to 0 dB (1dB steps) System default configuration: ‘–12’ (dB) for DAU/VAR8 ‘–6’ (dB) for VAR4/VAR12/VAR20

In a typical ASL system the overall 30 Hz surveillance tone level is set to:

• VAR4/VAR8/VAR12/VAR20: –4 dB

• DAU: –10 dB

b. Set the 20 kHz surveillance tone overall level to ensure a nominal 8 V RMS tone.

Menu: Configuration System Router Outputs All Outputs Surv-tone 20KHz(db)=–<db>

Possible values: –63 dB to 0 dB (dB) System default configuration: ‘–63’ (dB) for DAU/VAR8 ‘–6’ (dB) for VAR4/VAR12/VAR20

In a typical ASL system the overall 20 kHz surveillance tone level is set to:

• VAR4/VAR8/VAR12/VAR20: –16 dB

• DAU: –17 dB

c. Set the 30 Hz surveillance tone pulse width to 1.5 seconds.

Menu: Configuration System Router Outputs All Outputs Surv-pulse Width-30=15

Possible values: 10 to 99 (Divide by ten for time in seconds.) System default configuration: ‘15’

In a typical ASL system the 30 Hz surveillance tone pulse width is set to 1.5 seconds.



d. Set the 20 kHz surveillance tone pulse width to 9.9 seconds.

Menu: Configuration System Router Outputs All Outputs Surv-pulse Width-20K=99

Possible values: 00 to 99 (Divide by ten for time in seconds.) System default configuration: ‘99’

In a typical ASL system the 20 kHz surveillance tone pulse width is set to 9.9 seconds.

e. Set the surveillance tone cycle to 20 seconds.

Menu: Configuration System Router Outputs All Outputs Surv-pulse Cycle=20

Possible values: 5 to 40 (seconds) System default configuration: ‘20’

In a typical ASL system the surveillance tone cycle is set to 20 seconds.

2. Check the system design documentation to find the Router audio output number being used by the loudspeaker line and configure the surveillance tone settings for this output:

a. Set the output surveillance mode to ‘Pulsed’.

Menu: Configuration System Router Outputs Output# <O/P #nn – output name> Surv Mode=Pulsed

Possible values: ‘Pulsed’, ‘Off’, ‘On’ System default configuration: ‘Pulsed’

• ‘Pulsed’

A pulsed surveillance tone is generated by the Router and superimposed on the selected output. The surveillance tone frequency and level required by the AEL02 is specified in the following steps.

• ‘Off’

Disables the generation of the surveillance tone at the selected output, e.g. when the Router output is connected to a non-ASL amplifier system.

• ‘On’

A continuous surveillance tone is generated at the selected output.

b. Set the output surveillance tone frequency to ‘30+20K’.

Menu: Configuration System Router Outputs Output# <O/P #nn – output name> Surv Freq=30+20K

Possible values: ’30Hz’, 20KHz’, ‘30+20K’ System default configuration: ‘30Hz’

• ‘30Hz’

Low frequency surveillance tone with nominal frequency of 30 Hz is superimposed on the selected output. This is required by systems where the loudspeaker monitoring is performed using DC surveillance with EOL10K resistors and ‘DC blocking’ capacitors.

• ‘20KHz’

High frequency surveillance tone with nominal frequency of 20 kHz is superimposed on the selected output, as required by special applications.



• ‘30+20KHz’

Mixed 30 Hz and 20 kHz surveillance tone generated by the Router and superimposed on the selected output, as required by the AEL02.

The AEL02 derives the power from a 20 kHz tone, and monitors the line integrity by detecting a 30 Hz surveillance tone.

c. Set the output surveillance tone level to ‘–6dB’.

Menu: Configuration System Router Outputs Output# <O/P #nn – output name> Surv Level=–6

Possible values: –40 dB to 0 dB (dB) System default configuration: ‘–6’

In a typical ASL system using the AEL02 for loudspeaker line monitoring the surveillance tone level at the output is set to –6dB.

3. The correct set-up of the surveillance tones can be verified via the AEL02 internal LED; see Figure 9 (page 26).

• 1 s pulse (ON) every 20 s: the AEL02 is operating correctly and is set to ‘A’ mode.

• Two 0.5 s pulses (ON) every 20 s: the AEL02 is operating correctly and is set to ‘B’ mode.

• Other indication: a fault has been detected. There may be a line fault, the AEL02 operation mode may incorrectly be set, the surveillance tone settings may incorrectly be set at the Router, or the unit is faulty.



5.2 Commissioning the V400 Amplifier Mainframe and Amplifiers

Each amplifier may be commissioned for AC internal audio path surveillance, AC loudspeaker line surveillance, and Earth Leakage detection, depending on the installed Interface Card and loudspeaker line monitoring method.

In order to monitor a loudspeaker line with an AEL02 unit, commission the amplifier mainframe and amplifiers as follows.

Commissioning the Amplifier Frame:

1. Perform System Learn to allow the system to automatically detect the frame configuration.

Menu: Configuration System Learn

2. Confirm that the Router detected the correct operation mode, which is displayed with the amplifier type:

‘N’: Identifies a single circuit surveillance mode. ‘D’: Identifies a dual circuit surveillance mode. ‘L’: Identifies a loop return surveillance mode. ‘S’: Identifies a standby amplifier. ‘–‘: No amplifier configured in the slot.

The AEL02 requires either a single or dual circuit surveillance mode. Confirm that the amplifier is the required type.

• Single circuit surveillance mode:

The AEL02 unit connected to the loudspeaker line should be set to ‘A’ mode.

• Dual A/B circuit surveillance mode:

The AEL02 unit connected to the ‘A’ loudspeaker circuit should be set to ‘A’ mode.

The AEL02 unit connected to the ‘B’ loudspeaker circuit should be set to ‘B’ mode.

3. Commission the installed/updated frame so that the frame recognises the current amplifier installation as the correct one. In order to commission the frame press the SELECT key after learning the frame configuration.

4. Set the Earth Leakage to ‘EOL A/C Surv’ in order to enable the earth leakage monitoring and loudspeaker line monitoring using the AEL02.

Menu: Configuration Frames Frame #nn Slot #nn Earth EOL A/C Surv

Possible values: ‘Not Surv’, ‘Surveyed’, ‘EOL A/C Surv’ System default configuration: ‘Surveyed’

• ‘Not Surv’

The earth leakage resistance will not be surveyed. Therefore no earth leakage fault will be reported.

• ‘Surveyed’

The earth leakage monitoring is enabled.

Both speaker line phase conductors are monitored for resistance to earth. An earth leakage fault will be reported when the measured resistance is below the threshold value.



• ‘EOL A/C Surv’

The earth leakage monitoring is enabled and loudspeaker line monitoring is performed with one or two AEL02 units.

Both speaker line phase conductors are monitored for resistance to earth. An earth leakage fault will be reported when the measured resistance is below the threshold value.

The speaker line is monitored for short and open circuit using the AEL02. The appropriate fault will be reported in the event of open or short circuit.

5. Ensure that the DC Line surveillance is set to ‘Not Surv’.

Menu: Configuration Frames Frame #nn Slot #nn DC Line Not Surv

Possible values: ‘Not Surv’, ‘Surveyed’ System default configuration: ‘Surveyed’

• ‘Not Surv’

The DC Line surveillance is disabled in order that the loudspeaker line integrity monitoring is carried out using an AEL02 unit.

The Router automatically sets the DC Line surveillance to ‘Not Surv’ when Earth is set to ‘EOL EOL A/C Surv’.

• ‘Surveyed’

The loudspeaker line integrity monitoring is carried out using DC surveillance from the appropriate amplifier. The loudspeakers on the circuit are fitted with DC blocking capacitors, and an open or short circuit fault will be reported on any deviation from the configured number of EOL resistors on the loudspeaker line.

6. Set-up the amplifier surveillance parameters.

a. Set frequency to ‘LF Surv’ in order to select the 30 Hz low frequency surveillance tone.

Menu: Configuration Frames Frame #nn Slot #nn AC Level Frequency LF Surv

Possible values: ‘No Surv’, ‘LF Surv’, ‘HF Surv’ System default configuration: ‘LF Surv’

• ‘Not Surv’

The amplifier health is not monitored.

• ‘LF Surv’

The amplifier health is monitored by means of a low frequency AC surveillance tone with nominal frequency of 30 Hz which is superimposed on the Router output. The surveillance tone level is monitored at the amplifier input and output, and any reduction from the configured threshold levels will be reported as a fault.

In a typical ASL system (with or without AEL02 unit) this is set to low frequency.

• ‘HF Surv’

The amplifier health is monitored by means of a high frequency AC surveillance tone with nominal frequency of 20 kHz which is superimposed on the Router output. The surveillance tone level is monitored at the amplifier input and output, and any reduction from the configured threshold levels will be reported as a fault.



b. Set the input and output AC levels.

Menu: Configuration Frames Frame #nn Slot #nn AC Level Thresholds

The Router presents the input and output AC levels based upon a fixed proportion of the levels being detected. These detected levels can be used as the threshold levels. The user has the option to set other threshold levels. Any reduction from these threshold levels will be reported as fault if the AC surveillance is to be performed.

In an ASL system with the surveillance tone level set as specified in Section “5.1 Configuring the Router Outputs” (page 20), the typical thresholds values reported by the surveillance card are:

• Intellevac DAU200/DAU400:

Input Threshold = 135–202 mV / Output threshold = 900–1350 mV4

• VAR4/VAR8/VAR12/VAR20:

Input Threshold = 270–405 mV / Output threshold = 900–1350 mV4

c. Set the surveillance interval.

Menu: Configuration Frames Frame #nn Slot #nn AC Level Interval

Possible values: ‘00’ to ‘20’ seconds System default configuration: ‘20’ seconds

The system must detect pulses at this interval or more regularly. If pulses are not received within this interval a fault will be reported.

In a typical ASL system the surveillance tone interval is set to 20 seconds.

4 Output threshold value depends on the actual load connected to the loudspeaker line.
