Service explanation for JA-68
1 The JA-68 universal output module
The JA-68 is a universal output module designed for the Jablotron systems of the JA-80 OASiS, JA-63 Profi and JA-65 Maestro series. The module provides eight factory pre-programmed semi-conductor outputs and a switch-over relay output. The relay can be configured using 10 DIP switches that allow you to command multiple functions. There is no limit to the number of JA-68 modules used in the system. The JA-68 can be combined with GSM, LAN or PSTN (landline) dialers.
The module is designed to be placed in the control panel housing.
2 Semi-conductor outputs
All semi-conductor outputs are switchable to a common terminal marked "C". The switch ON/OFF logic can be reversed by setting a jumper JP1 to the NC position (the default setting is NO).
Description of the codes:
| Code | Function |
| +U | Positive power supply from the digital bus (limited to 200 mA) |
| GND | Negative pole of the diet |
| c | Common code (for all semi-conductor outputs) |
| POOR | All-set status (A or AB or ABC) |
| ALM | Burglary alarm |
| FIR | Fire alarm |
| TMP | Sabotage alarm |
| PNC | Panic alarm |
| FLT | Fault notification (general faults, radio communication faults, backup battery faults |
| AC | Socket (230V) power supply error |
| L.B | Low battery indication (applies to wireless devices, such as detectors, control panels, sirens or thermostats) |
Table 1
3 Relay configuration
The relay is adjustable via a set of 10 DIP switches (see Table 2). The relay works with OR logic: It switches on if there is at least an activated preset function.
Example: Setting switches 2,3,4 and 5 to ON causes the relay to indicate: burglary, fire, tamper or panic alarms. The relay switches ON when any of the four mentioned states of alarm are activated.
DIP switches commands:
| Number | Tag | Function |
| 1 | POOR | Everything set |
| 2 | ALM | Burglary alarm |
| 3 | FIR | Fire alarm |
| 4 | TMP | Sabotage alarm |
| 5 | PNC | Panic alarm |
| 6 | FLT | System disruption |
| 7 | AC | Power supply error |
| 8 | L.B | Low battery |
| 9 | PGX | Central PGX output |
| 10 | PGY | Central PGY exit |

Description of the relay codes:
| Tag | Description |
| NC | Normally closed relay |
| c | Common relay contact |
| NO | Normally open relay contact |
Note: There is a minimum output activation time of 10 seconds for each of the 8 + 1 outputs
