Input Balanced/Unbalanced:
The input may be selected to be balanced or unbalanced. The J1 jumper determines whether
the input is balanced or unbalanced. Removing the short from J1 will make the input
balanced. Consult FIGURE 3 for the J1 jumper location.
5 Minute Restoral:
The 3185E may be selected to restore the output status for a power interruption of less than
five minutes. The 3185E is factory set to enable this restoral. The J7 jumper is open. To
disable the five minute restoral install a jumper on J7. Consult FIGURE 3 for J7 location.
20 Minute Reset:
A 20-minute reset is provided to reset the output relay 20 minutes after the 'ON' code was
received or the ‘Set’ input was momentarily connected to circuit common. This option is
factory set disabled. To enable the option install jumpers on J3 and J4. Consult FIGURE 3
page 7 for the locations of J3 and J4.
Output Relay:
The output relay on the 3185E may be set in three different modes of operation; latching,
momentary or alternate action (toggling). The 3185E is factory set to latching.
Being set at latching means the output relay will energize when the pre-programmed 'ON'
code is received or the ‘Set’ input is momentarily connected to circuit common. The output
relay will remain energized until the preprogrammed 'OFF' code is received or the ‘Reset’
input is momentarily connected to circuit common.
When the output relay is programmed to operate in the momentary mode, it will energize for
the duration that the last valid digit is present. In the momentary mode the 3185E will not
respond to its pre-programmed 'OFF' code.
Alternate action programs the relay for latching (toggling) relay output. In this mode the output
relay energizes and de-energizes with the same pre-programmed 'ON' code sequence.
10 Second Pulse:
If both ‘Set’ and ‘Reset’ are low and the relay mode is ‘momentary’, then when a valid ‘ON’
sequence of digits is received, the relay is turned on for 10 seconds then ‘OFF’ – even if the
last tone is still present. The decoder will ignore all tones and ‘Set’ and ‘Reset’ activities
during the 10-second period. Applies only to firmware version 80154-1.10 and later.
