Switch S3-3 (DET3 VENTL) 
Switch S3-3 configures DET3 for low pressure switch (LPS) monitoring or LPS and/or 
vent monitoring.   When the switch is in the left position, the control panel requires a two-
wire loop connected to terminals 24 and 27.  The loop connects the LPS of each HRD 
extinguisher in series.  The opening of an LPS will cause an open condition on DET3 
and put the control panel in a trouble condition. 
When the switch is in the right position, the control panel requires two 2-wire loops.  One 
loop is connected to terminals 24 and 25 and the other loop is connected to terminals 26 
and 27.  Extinguisher low pressure switches are series wired in either loop for low 
pressure monitoring.  In addition, the normally closed contact of a vent monitoring limit 
switch is wired into the four-wire circuit as shown in Figure 9.  If the vent panel ruptures, 
the normally closed contact opens signaling the control panel to actuate the suppression 
system. 

 

Figure 9: DET3 Vent Monitoring Wiring Schematic 

 
Switch S3-4 (DET2 IRL) 
Switch S3-4 configures the function of DET2.  When the switch is in the left position, 
DET2 functions as a normal detection circuit.  The input signal is processed in the same 
manner as DET1.  When the switch is in the right position, DET2 signal is recognized by 
the control panel as a pre-alarm signal.  The pre-alarm signal only causes the ALARM 
indicator to flash, the horn to sound continuously, the Alarm relay to energize and the 
Trouble relay to de-energize.  It does not activate the EED and Firewolf™ devices. If an 
Alarm occurs on DET1 simultaneously with or following a Pre-Alarm on DET2, an Alarm 
will be generated and the EED and Firewolf™ devices WILL be activated. 
 
 
Switch S3-5 (LATCH TRL) 
The control panel trouble relay can be programmed as non-latching or latching as best 
suited for the application.  With the switch in the left position, the trouble relay is non-
latching such that if a trouble condition that was present is cleared, the FAULT indicator 
would turn off and the trouble relay would energize without manual intervention.  With 
the switch in the right position, the trouble latches.  The FAULT indicator remains on and 
the trouble relay remains de-energized, even if the trouble is cleared, until the control 
panel is manually reset.
