Whilst any Detectors are in a Backup Alarm condition the Accept key is inoperative until the oil 
mist level drops below 3.0mg/l. 

It is possible for a healthy Detector to produce a Backup alarm if the level of oil rises very rapidly. 

NOTE - The Backup Alarm will not operate the Slowdown/Shutdown Relay 

3.17

 

RELAY OPERATION 

Communication  of  alarm  and  fault  conditions 
Management System (AMS) is via a series of volt free contact relays. Individual relays are provided for 
Pre-Alarm,  Slowdown/Shutdown  Alarm,  Backup  Alarm  and  Fault.  For  each  output  connections  are 
provided to the relay common, normally open and normally closed contacts providing the flexibility to 
meet the interface requirements of the AMS. 

The actions of the relays are detailed below: 

Pre-Alarm Relay 

Activated  when  the  oil  mist  level  of  a  detector 
rises above the configured pre-alarm level. 

Slowdown/Shutdown Alarm Relay 

Activated  when  the  oil  mist  level  of  a  detector 
rises  above  the  configured  slowdown/shutdown 
alarm level. 

Backup Alarm Relay 

Activated when oil mist level of a detector rises 
above 3mg/l for a period of 5sec or more. 

Operation of the Backup Alarm Relay is software 
independent and cannot be reset until the oil mist 
level falls below 3mg/l.  

Fault Relay 

The  Fault  Relay  is  normally  activated  and  de-
activated when a fault occurs on the Control Unit 
or Detectors. 

In the event power is lost to the Control Unit the 
relay is de-activated ensuring a fault is indicated 
to the AMS. 

 

A graphical representation of the relay operation is shown below:
