Gorman-Redlich 257 West Union Street, Athens, Ohio 45701 Phone: (740)-593-3150; Fax: (740)-592-3898 http://www.gorman-redlich.com; email: jimg@frognet.net USING THE TELEPHONE INTERFACE on the EAS-1 ENCODER/DECODER NOTE: In these instructions, when there are brackets around a word, number or symbol, e.g., , it is referring to a key on the EAS-1 keypad or the telephone keypad. Anything in a four-line format (or less) with the top line bracketed by triple hyphens (--- ---) refers to the EAS-1 4-line, 40-character LCD display. 1. To initiate an EAS-1 telephone session, first make sure that the telephone line is plugged into the jack in the back of the unit. 2. Check the EAS-1 phone support in the EAS-1 menu. To do this, first press the button (<7> on the EAS-1 keypad). Using the keypad, enter the four-digit technician code. When the menu appears, press the down arrow to scroll down until you reach the menu item 16 on the third screen, PHONE SETUP. Press on the EAS-1 keypad. You will then see this screen: --- SETUP PHONE SUPPORT --- ARROW TO SET, EXIT TO EXIT > PHONE SUPPORT IS ON , ENTER TO CHANGE PHONE PARAMETERS, ENTER TO CHANGE If the third line is PHONE SUPPORT IS OFF. . . then press on the keypad to turn it on. Press the down arrow on the keypad to the fourth line, PHONE PARAMETERS. . . then press . You will then see this screen: --- SET PHONE PARAMETERS --- EXIT KEY TO EXIT, SELECT 1 OR 2 1 # RINGS TO ANSWER 1 2>3 4 5 6 7 8 9 2 # SECONDS TO HANGUP 10 20>30 40 50 60 These are the default values: 3 rings to answer (the EAS-1 will establish the phone connection after three rings) and 30 seconds to hangup (the EAS-1 unit will disconnect the phone connection if no signal is received on the phone line for 30 seconds). Press either <1> or <2> on the EAS-1 keypad, then use the down arrow or the up arrow <^> to re-select the desired value. Then press three times to return to the operational screen. 3. Dial the appropriate number from a telephone. At this time, the EAS-1 display should include the phrase "incoming phone." 4. The unit will establish the phone connection after the prescribed number of rings, as set in EAS-1 menu item #16, submenu phone parameters (see second screen, above). The default is three rings. When the unit answers, wait for a brief ACK tone ("acknowledged", a short burst of 2083 Hz.). 5. After you hear this tone, enter the four-digit passcode (operator password for your EAS-1) from the telephone keypad, followed by the <#> sign. You should then hear another ACK tone acknowledging the connection. If you hear a NAK tone ("not acknowledged", a burst of dual tones 853 and 960 Hz., slightly longer than the ACK), the passcode was not accepted; try again. 6. After the passcode is accepted and the connection is established, you may use the phone interface. Pressing the <*> sign at this time should return a NAK tone. 7. The following operations may then be done from the phone (preceeded by their phone pad codes): <1><#> Send weekly test (RWT). 1# is all that's needed. The unit will automatically generate the three FSK header tones and the three EOM tones. <2><#> Send monthly test (RMT). Automatically generated, including FSK header -> ATT tone -> recorded voice message -> EOM. A voice message MUST be recorded first (4#). If no new message has been recorded during the CURRENT phone session, a NAK tone will be returned. <3><#> Send civil emergency message (CEM). Automatically generated, including FSK header -> ATT tone -> recorded voice message -> EOM. A voice message MUST be recorded first (4#). If no new message has been recorded during the CURRENT phone session, a NAK tone will be returned. <4><#>. . .<#> Record voice message. Press 4#. After you then hear the short ACK tone, speak into the phone to record your message. When the message is finished, pause briefly, then press the <#> key again. You should hear another ACK tone that confirms completion of the voice message. A voice message must be recorded during the CURRENT phone session before you can send an RMT (required monthly test, 2#) or CEM (civil emergency message, 3#). <5><#> Play back voice message. Press 5#. You will hear a short ACK tone, followed by the currently-recorded voice message, followed by another ACK tone on completion of the message. This message may be from the previous phone session; if so, you must record a new message before an RMT (required monthly test, 2#) or CEM (civil emergency message, 3#) may be sent. <6><#>. . .<#> Direct voice link. Press 6#. You should hear a double ACK tone. After the double tone, the connection is established and anything spoken into the phone will be put out over the air. Press <#> again to end the session. To confirm completion of the direct phone link you will hear another ACK tone. In cable mode only, 7#, 8# and 9# also establish a direct voice connection. <0><#> Disconnect (hang up). Press 0#. This should be done before physically hanging up the phone; otherwise the EAS-1 unit will not promptly disconnect from the phone session, but will wait for the number of seconds to hangup selected in EAS-1 menu item #16. After pressing 0#, you should hear an ACK tone. CAUTION: In the menu item for the phone connection on the EAS-1, there is a hangup time specified, with a default of 30 seconds (but you may modify it for intervals from 10-60 seconds). The EAS-1 will automatically disconnect if no signal is sent over the phone line for this period of time. Therefore, if you are connected in a phone session but must pause for longer than this period, pressing the <*> key on the telephone keypad periodically (returning a NAK tone) will prevent hangup.
