ADEMCO 678 Installation Instructions Manual

digital communicator that transmits coded messages over ,the telephone system to a digital receiver located at a central monitoring station. Special leased lines are not required. (There is a 9th channel dedicated to user test and optional low ba=y reporting.) To accommodate various receivers, the 678 can transmit in three formats: I) Ademco (and Silent Knight), 2) Ademco High Speed or 3) Sescoa/Franklin/DCI. The 678 consi sts of a printed ci rcuit board chassis Bnd cover that may be in&a I led in any suitable enclosure, such as the Nos. 204 or 205 Cabinets, or the lower section ...

is activated; transm as follows: . iss ion to the central monitoring station occurs , I. After the normal 150 millisecond response time (or I6 seconds delay if so programmed) the 678 executes line seizure and forces .a 1.6 second hang-up to insure a disconnect if an outqoinq call was beina made. @: The 678 has a built-in ACTIVATION LED which lights wh&ever the unit is activated. 2. Next, the 678 checks for dial tone. To shorten the time required for contacting the central monitoring station, the 678 can sense internal dial tone as well as external (telephone company) dial tone’. 3. If dial tone is detected, the 678 immediate ...

Subscriber 1890 go into alarm, the 678 will respond as follows in conjunction with an Ademco 660 (or Silent Knight; SESCOA, Frahkiin or DCI) Receiver: 890 3 890 3 “kiss-off” 890 6 890 6 Final “kiss-sff” (No. 678 hangs up) Note : Only the last 3 digits of the subscriber identification number will in this case be sent. The full 4 digits will be used in conjunction with an Ademco No. 685 High Speed Receiver (available soon). If the 678 does not receive the “kiss-off” code(s) by the time it has sent its message(s) four times, it hangs up and dials again. Up to a total of 8 attempts *or “Un I i m i ted Attempts� ...

Reports all information to the second, telephone number after receiving kissoff from the receiver at the primary number. In the event that 8 attempts are made, but no “kiss-off” is received from the primary number, the No. 678 will then make 8 more’attempts to report to the secondary number. c-3 :, ,: Note: When Dua I Report is’ used, xbe programmed. Unlimited Attempts (System Option 7)should Alternate by Pairs: The dialer will’attempt to fall the primary number twice, then, if “kiss-off” has not been received, it will make two attempts to reach the receiver at the secondary number. It w i I I a I ter ...

code 9. For example, for subscriber No. 1890 the No. 678 will report: 890 9 890 9 “Ki ss-off “------hang up If a channel is selected as both an Open/Close Channel and a Delay Channel, the delay applies to the input being applied and the in- being removed. Since Code?9 can also mean test, use caution.Tso since the channel is not identified upon removal of input, restrict’this method to one channel. 3. Restore,ChanneIs: Channels so designated will not only report when the input voltage goes high (alarm) but will report aga ...

tie the inputs of channels 4 and 5 together and then to the control unit. Program channel 4 (input going low) for inverted operation. In this case DO N’OT program either channel 4 or 5 for Open/Close or for Restore. Note: I6 set delay, if selected, will apply when signal is removed from thexerted channel. Channels 4 and/or 5 or any other combination used this way may be programmed for Long Delay or Second Number Only (as desired). The “Kiss-off” (Ring-Back) Feature is an important tool when transmitting test or opening/closing si, ...

eliminates the ambiguities present in the LOW SPEED format between channel 8 (code 8 in LOW SPEED) and low battery (also code 8 in LOW SPEED). In HIGH SPEED, low battery is reported as a channel 9 status, thus freeing use of channel 8 for alarm reporting (its use in LOW SPEED having been precluded when I’ow battery reporting was selected). .I- .: Similarly, OPEN/CLOSE programming is restricted to a single channel when standard LOW SPEED Ademco (or SESCOA) format is used (to avoid confusing code 9 “close” with code 9 “test”).~ When HIGH SPEED format is used, however, this rest ...
