14 1X-X3 Operation Manual
Mode A: When the MCP Hold is activated, the actuator delay countdown
continues, but the panel is prevented from entering the extinguishing activation
state. When the MCP Hold is deactivated, the delay countdown determines when
the panel enters the extinguishing activation state.
In Mode A, activation of the MCP Hold turns on the MCP Hold LED, which stays
on until the panel is manually reset. The yellow Preactivation LED flashes to
indicate that the panel is being prevented from entering the extinguishing
activation state. The Preactivation LED flashes to show when the MCP Hold is
on; it turns off when the MCP Hold is off.
Mode B: When the MCP Hold is activated, the actuator delay countdown stops,
putting the extinguishing release process on hold. The sounders emit a unique
sound pattern (1 second on, 4 seconds off) while the extinguishing release
process is on hold. When the MCP Hold is deactivated, the delay countdown
restarts and the sounder pattern changes to the tone configured for extinguishing
activation. The MCP Hold LED turns off when the MCP Hold device is
deactivated.
Extinguishing released
The control panel is in this state when:
• The actuator output to release the extinguishing agent has been activated
and the agent flow confirmation is not configured or is disabled.
• The actuator output to release the extinguishing agent has been activated
and the agent flow has been confirmed, when agent flow confirmation is
configured.
Consult your system installer to determine the option configured in your system.
An extinguishing released state is indicated as follows:
• Released LED: Steady.
• Extinguishing Agent Flow LED: Steady, if confirmation is configured.
• Preactivation LED: Steady red, unless extinguishing agent flow confirmation
configured and received, but no extinguishing activation event occurred.
• General Fire Alarm LED: Steady. The Alarm relay activates.
• MCP Start LED: Steady if the alarm was activated by a start extinguishing
manual call point.
• Extinguishing Sounders On LED: Flashing (for intermittent tone) or steady (for
continuous tone) according to your system configuration.
• Optical Panel On LED: Steady to indicate that the output to activate the
optical warning panel or sign is active.
• Reset LED: Flashing slowly, to indicate that manual reset is disabled until the
configured delay expires.
