Illuminated when the interlock input (e.g. from dampers, doors etc) is off
during the discharge sequence
–
meaning the dampers, doors etc are not closed as they should be or a fault
exists. The “Interlock” is overridden after 10 seconds and the agent is released
Note:
The Interlock is a Monitored Input and can be defaulted to the ON position by terminating the
input (TB2 7 & 8) into a 2K2
resistor.

RESERVE AGENT
(Yellow)
Illuminated when the “Reserve Agent” is selected.

–
a manual release sequence of the
agent is started.
The MCP is fitted with a protective flap
–
so two actions are required to release the agent

lift the flap and
activate the MCP
