Operation
Monroe Model 988 interfaces a two-wire (POTS) telephone service with control
switching and audio control signals to an FCC approved encoder/decoder.
Upon answering, the unit begins playing back the message stored by the operator,
and looks for a series of DTMF tones corresponding to the three-digit access code.
After picking up the telephone line, if no activity is detected for a period of 1
minute, the unit disconnects the telephone line. If the user does not enter the
correct access code within a period of 1 minute, the unit will disconnect the
telephone line.
Once the telephone caller enters the three-digit access code, the unit will cease
playing the message and proceed to the next stage of operation.
Additionally, after the access code has been entered, two separate relays will
actuate. Contacts are available on the screw terminals of the connector as Switch
1 and Switch 2.
The Caller must select the FIPS code(s) to be sent out with this alert.
To select individual FIPS codes (previously stored in the 988) type their stored
number Ex. 1,2,3, followed by the # key to accept. If an incorrect number is
entered three beeps will be heard and the user must start the selection over. The
user has three tries to enter correct values or the unit will disconnect. To send all
of the stored FIPS codes, simply press the # key.
After a tone, approximately 10 seconds long, speak the audio message you wish to
broadcast with the local alert.
When done, press the # key or hang up the telephone.
