Input Impedance:

 

Input impedance may be either 10 k

 or 600 

. The 

J2

 jumper determines the input impedance of the 

3185E. Install a jumper at position 

J2 

to terminate the audio input in 600 

. Consult FIGURE 3 for the 

J2

 

jumper location. 

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. 

Momentary Output for ON & OFF:

 

This  setting  provides  a  momentary  output  relay  activation  for  both  the  ON  sequence  and  the  OFF 

sequence. Momentary duration is 1 second. To enable this feature, install both 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 

rece

ived  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.
