20)  Product Coding for Fault Resistor and Customer EOL Resistor 

 
The customer is able to identify the resistor values chosen on purchase from the product code. 
This is represented by the last three characters:  

D1xS1FDC024AB1S1R-

AFZ

 

 

 

The first A character denotes the value of the Fault Resistor (FR) Default value is 2.2 k

Ω (Code = A) 

unless an alternative value is requested 

when ordering. 

 

 

The second F character denotes the value of the Current Sense Resistor (CSR) Default value is 3.3 k

Ω (Code = F) unless an alternative 

value is requested when ordering. 

 

 

The third Z character denotes the value of the unit End Of Line Resistor (EOL) By default no EOL is fitted (Code = Z) A factory fitted EOL 
resistor can be specified when ordering. 

 
The values of resistors available are shown in table 7 below.

Default resistor coding as follows.

Example of a custom requirement resistor coding:

Where the (FR) Fault Resistor is (G = 3.9 kΩ)

 

(CSR) Current Sense Resistor is (E = 2.7 kΩ)

 

(EOL) End Of Line resistor is (F = 3.3 k

Note

: To utilise the full monitoring functionality the 4-wire configuration is recommended. An EOL resistor is not required for this configuration. 

 
The alternative 2-wire configuration requires an EOL resistor to be fitted. The EOL resistor can be specified during ordering and factory fitted or selected 
and fitted during the alarm horn sounder installation. 
 
See section 9 for EOL resistor location and wattage requirements. E2S recommends a value of 2.2K Ohm. If an alternative value is required, please 
see section 16-2. 
 
Both the (FR) Fault Resistor and (CSR) Current Sense Resistor are factory fitted and cannot be user replaced.
