Test 

 

General checks on NK8237 

The power supply, vital functions, and diagnostic state of NK8237 can be checked 
on the front panel. Refer to 4.1 at p.12.  

On the Modbus interface, the 

LifeCheck

 register provides a incremental counting 

as long as the NK8237 communication with the fire system and with the Modbus 
station works properly. 

For more advanced diagnostics, see 9.1 at p. 54. 

Checking the Modbus connection 

The serial line state can be monitored from the LEDs of the NK8237 front panel. 

A complete check can be done from the Modbus unit. 

Checking the fire system 

If the Modbus communication works, detailed information is provided for each fire 
control unit. A complete check of the fire detection points is required before hand-
ing over the system. 

For a complete documentation of the fire point mapping, refer to the 

NK8237 Mod-

bus Interface Specifications

 (document no. A6V10316242). 

 

 

 

 

 

Please be aware of the potential consequence of a configuration mismatch be-
tween the fire system and the Modbus master station that deals with the safety 
alarm presentation and treatment. Such a mismatch can actually result in a fire 
alarm being missed. 

Whenever a configuration change occurs in the fire system and/or in the NK8237 
gateway, make sure to thoroughly and consistently import and set up a corre-
sponding configuration into the Modbus head-end system. 

Note that the configuration inconsistency between the fire system and the 
NK8237 is detected and reported in the Modbus map (refer to the 

NK8237 Points

 

register documented in the 

NK8237 Modbus Interface Specifications

.)
