Function F52 Physical Input Trigger Configuration
You can configure the Input to trigger on normally open (N.O.) or normally closed (N.C.)
contacts. The pull-ups may be changed to pull-downs by moving the appropriate Input channel
jumper (see Jumper Settings in the Installation section). Any unused Inputs must be treated as
normally open.
The EDAC 222-02 can latch an Input so that, even though the physical trigger is removed or gone
back to its normal state, the EDAC 222-02 continues to make alarm notification calls. The Input
latches after the latch time as defined in function F09. Function F96 determines how the time in
function F09 is applied and in what units (Seconds or Minutes).
By default the Input triggers are set up to be non-latching. This means that when the Input trigger
is removed, the EDAC 222-02 will stop making alarm notification calls.
By default the Input is set up for normally open. Connecting the Input terminal to negative supply
will trigger the EDAC 222-02.
Alternatively the Input can be set up for normally closed, Input terminal connected to negative
supply. Opening the connection will trigger the EDAC 222-02.
The trigger type for Input one is set as follows:

52
 
0 = Normally open and Input will not latch.
1 = Normally open and Input will latch.
2 = Normally closed and Input will not latch.
3 = Normally closed and Input will latch.
Default: 0 (Normally open)
By default both Inputs are set to normally open and Input will not latch. Both Inputs must be
programmed separately to change them from normally open non-latching as follows:
 Use F52 for Input 1, as in the example above.
 Use F62 for Input 2.
