Appendix C: Engineering Specifications

C. Voice Messages
The system shall have the ability to record, store and reproduce
voice messages to articulate the location and status of the moni-
tored channels. In absence of user-recorded messages, the system
shall articulate channel status using the internally resident vocabu-
lary. All digitized speech message data shall be stored in nonvolatile
memory with a 3V lithium battery backup. Such battery backup shall
be capable of protecting speech memory for at least 5 years of
complete power outage.
There shall be one recorded identification message for the system, a
recorded message for each temperature input and 1 recorded
message for the auxiliary input. Message length shall be 5 seconds
per input channel and 10 seconds for the identification message.
D. Beeper/Pager Dial out
The system shall be capable of intelligently dialing out to a numeric
beeper or pager. The dialing sequence shall be programmable such
that the pager number is dialed, the system waits for the telephone
to be answered, and then additional identification Touch Tones™ are
transmitted.
IV. Programming
A. Local Programming
The system shall contain an integral, sealed keypad for the purpose
of locally programming all system data. All programming parameters
as well as system status information shall be displayed on the LCD.
V. Remote Operational Features
A. Status Report
The system shall allow the user to call into the unit at any time using
any standard telephone to obtain a full status report of all monitored
channels including present temperature and listening-in to on-site
sounds. The status report shall be articulated using the resident
digitized vocabulary in combination with user-recorded voice
messages.
B. Acknowledgment
An alarm on any monitored channel may be acknowledged remotely
by pressing tones on a Touch Tone™ telephone keypad. An alarm
may also be acknowledged locally using the built-in keypad.
