4 Configuration and Programming 
4.1  Selecting connected device options (DIP switches) 
A series of DIP switches are used to configure devices connected to the fire alarm control panel. DIP 
switches are located in the lower right corner of the panel. 
DIP Switch 9  Description of Disabled States 
(Switch to left side) 
Description of Enabled States 
(Switch to right side) 
1. B1 Strobe  NAC 1 devices are silenceable.  NAC 1 devices are non-silenceable – 
requires panel reset to silence. 
2. B1 Temporal  NAC 1 rings constant  NAC 1 rings for 3 pulses and then stops 
for 1 pulse (1/2 second per pulse) 
3. TRBL-REM ALM  Remote alarm trouble disabled.  Remote alarm trouble enabled. 
4. ANNUNC DISC  Remote annunciator is not used or 
annunciator input is ignored. 
Remote annunciator is used and 
annunciator input is accepted. 
5. Z1- Waterflow  Zone not waterflow switch (silenceable)  Zone waterflow switch (not silenceable) 
6. Z1- Verify  Zone not verify  Zone verify 
7. Z1- Class A  Zone Style B (Class B)  Zone Style D (Class A) 
8. Z2- Waterflow  Zone not waterflow switch (silenceable)  Zone waterflow switch (not silenceable) 
9. Z2-Verify  Zone not verify  Zone Verify 
10. Z2- Class A  Zone Style B (Class B)  Zone Style D (Class A)

2. Z3- Verify  Zone not verify  Zone verify 
3. Z3- Class A  Zone Style B (Class B)  Zone Style D (Class A) 
4. Z4- Waterflow  Zone not waterflow switch (silenceable)  Zone waterflow switch (not silenceable) 
5. Z4- Verify  Zone not verify  Zone verify 
6. Z4-Class A  Zone Style B (Class B)  Zone Style D (Class A) 
4.1.1  B1 Strobe device 
Place the B1 STROBE switch in the “on” position (right side of the switch) when NAC 1 is a non-
silenceable circuit (for devices such as strobes). When enabled, the circuit cannot be silenced during 
alarm except by resetting the panel. 
4.1.2  B1 Temporal pattern 
Place the B1 TEMPORAL switch in the “on” position (right side of the switch) when you wish NAC 1 to 
ring a temporal pattern. A temporal signal consists of three rings and one pause as defined by NFPA 72, 
Section A-3-7.2 (2).
