The programming of jumpers for the output relay is shown below. Consult FIGURE 3 page 7 for the 'J3'
jumper and the 'J4' jumper location.
Number of Digits to Decode:
The 3185E is factory set to decode a 4-digit 'ON' code sequence and a 4-digit 'OFF' code sequence.
The first three digits of the code sequence are the same for both 'ON' and 'OFF'. The fourth digit for the
'ON' code sequence is factory set to '*', and the fourth digit for the 'OFF' code sequence is factory set to
'#'. The number of digits to decode is determined by jumpers 'J6' and 'J5'. Consult FIGURE 3 page 7 for
the location of 'J6' and 'J5'.
The programming of jumpers for the number of digits to decode is shown below:
Fourth Digit ON/OFF:
The fourth digit of the 'ON' code sequence and the fourth digit of the 'OFF' code sequence are factory
set at '*' and '#' respectively. To enable user selection of the fourth digits, it is necessary to remove
resistor 'R8" and install two additional selection switches, S4 and S5, plus IC A3. When ordering the
switches, please use Digital Alert Systems part number '9200002' for each of the two switches and part
number '9120375' for the IC required.
Consult the PC board layout in Figure 1, on Page 4, for the location of the parts to be removed and
inserted.
