5. Replaying Messages

Once the phrases have been recorded it is possible to play them back through the built in

loudspeaker.

The following example shows how to play back "Message A" (Phrase 0 + Phrase A):

Ensure that the SD1 is initialised and the

display is showing "READY".

After a short delay the display will show

"PLAYING PHRASE 0", then "PLAYING

PHRASE A".

Repeatformessages BandC,asrequired.

6. Call Acknowledgement Procedure

When the call is answered, the message is played. At the end of its message the SD1 sends

an audible "beep" which must be answered within 2 seconds using the tone generated by

pressing the [8] button on a standard telephone. On hearing the [8] tone the SD1

immediately sends another "beep" which must be answered in the same way. If successful,

a multi-tone confirmation signal is then heard, if not then the message is repeated with the

acknowledgement "beeps" again.

Points To Note:

1. The SD1 will not acknowledge signals from Pulse Dialling telephones or those with

short duration tones. Check all recipients phones by calling them and getting them

to press their [8] button. If a series of clicks is heard (or the tone cannot be

sustained by holding down the button) then a Tone Dialling Simulator will be needed

to successfully acknowledge the SD1 messages (Contact your installation company

for details).

2. No harm is done by not acknowledging the message as the unit simply repeats it

four times and then aborts the call.

3. The procedure is fast and should be practised by all recipients under test conditions.

The [8] button must be pressed within 2 seconds of each "beep" and should be

held down for between

to 1

seconds. If either tone is not 'seen" by the SD1 the

message is repeated again.
