Specifications & features
- An optional system expansion device for use with the EP203/CON three zone automatic extinguisher panel.
- Mounts inside the EP203/CON panel to provide five volt free relay contacts (reset, mode, discharged, hold and abort).
- Reset relay switches during the panel’s reset cycle.
- Mode relay switches when the extinguishant system’s mode is changed to manual.
- Discharged relay switches when a released flow switch input (e.g.
- from the extinguishant pipework) is received to indicate the extinguishant has been released.
- Hold relay switches when a hold input is received at the panel.
- If the panel is in 2nd stage alarm (i.e.
- it is in automatic mode and detection circuits are activated, or it is in either automatic/manual mode and a manual release input is operated) the extinguishant release sequence is halted.
- Abort relay switches when an abort input is received at the panel to cancel the extinguishant release sequence.
- Single pole changeover contacts;
- Rated at 1A 30V DC.
- DO NOT use to switch Mains voltages.
