3.4.4.1 Meaning and Use of E&C Equation
1. Use of E&C Equation
An E&C consists of conditions, relation character and results. By setting the E&C
equation, the FACP can be programmed to activate some equipment on an alarm.
Note: Definition of E&C has to be done after device definition.
2. Structure and Meaning of E&C
A condition item can consist of several trigger conditions, the relationship among the
trigger conditions is
“or”. Each individual trigger condition consists of several triggering
devices. Only when all these triggering devices alarm, will the trigger condition be
satisfied.
Below is an example:
00100101&00100201
＋
00100101&00100301
＋
00100201&00100301
＋
00100101&00100201&00100301
＝
00100441
In this E&C equation:

The part before the
“=” sign is the condition

The part after the
“=” sign is the result
 “&” means “and”
 “+” means “or”

001 001 01
The 7
th
and 8
th
digit represents device type
The 4
th
, 5
th
, and 6
th
digit represents the device code.
The 1
st
, 2
nd
and 3
rd
digit represents zone number.
Meaning of this E&C equation: Any two of the three detectors (001, 002 and 003) in Zone
1 alarm, Sounder 4 of Zone 1 will be activated.
3. Meaning of asterisks
“*” in E&C equation and how to set up an E&C.
Example: 00100*01&00101*01+00103*01&00104*01
＝
00100441
 “*” represents any number between 0 ～
9, which can be entered by pressing the *
key;

Input of
“&” mark: The software will automatically add a “&” mark after 8 digits
