MS-9200UDLS Trouble Codes

The automatic 24-hour communicator test failed or was attempted while the system was in an off-normal state.

The control panel has lost its primary AC power source.

The panel has detected that the primary AC power has dropped too low or failed, causing the AC POWER indicator to extinguish and the system trouble indicator to activate.

Communication failure with an ACS Annunciator device.

Supervisory operation indicates a condition that is similar to an alarm but typically monitors system components like sprinkler valves or pressure switches to ensure they are in their normal state.

This condition indicates that the Notification Appliance Circuits (NACs) have been silenced by pressing the Alarm Silence key while an alarm condition exists.

A general fault related to the system standby batteries.

The internal battery charging circuit is not operating within normal parameters.

Indicates a communication failure between the panel's internal Digital Alarm Communicator/Transmitter (DACT) and the central station.

The communicator failed to successfully transmit a report to the central station using line 1.

The communicator failed to successfully transmit a report to the central station using line 2.

A point (detector or module) has been manually deactivated in the system programming, which causes a system trouble condition until the point is re-enabled.

A duct smoke detector has entered a supervisory state.

The panel is in Walktest mode, which is an off-normal condition.

A ground fault indicates that a portion of the system's circuitry has an unintended connection to the earth ground, which can compromise the panel's immunity to transients.

Communication failure with an LCD-80F remote annunciator.

The standby battery voltage has fallen below the required threshold.

A device requires maintenance or a presignal delay is active.

The panel has detected a checksum error or corruption in its internal memory.

A monitor module programmed for supervisory operation has been activated.

Notification Appliance Circuit 1 has been manually disabled.

A fault condition (open or short) has been detected on Notification Appliance Circuit 1.

A fault condition (open or short) has been detected on Notification Appliance Circuit 2.

A fault condition (open or short) has been detected on Notification Appliance Circuit 3.

A fault condition (open or short) has been detected on Notification Appliance Circuit 4.

A fault related to the internal NAC activation logic or hardware.

The control panel does not detect any batteries connected to the charging circuit.

The panel is programmed for addressable devices but does not detect any on the SLC loop.

The system is in a state other than normal standby, such as programming or test mode.

This condition indicates that the control panel has detected a break in the wiring or a missing end-of-line resistor on a Notification Appliance Circuit (NAC).

An open circuit exists on a control module's Notification Appliance Circuit (NAC) or a monitor module's Initiating Device Circuit (IDC).

A circuit is electrically open and cannot monitor for alarms.

The panel has lost communication with an internal option module.

An addressable point has been manually disabled by the user.

A general fault condition associated with a specific addressable device.

A monitor module assigned to power monitoring has detected a loss of power.

The panel has lost communication with the local printer or the printer is in an error state.

A monitor module assigned to process monitoring has been activated.

A fault has been detected on the remote synchronization output circuit.

A break in the wiring of the Signaling Line Circuit (SLC) loop has been detected.

This trouble indicates that a short circuit condition has been detected on the Signaling Line Circuit (SLC) loop, which prevents normal communication with addressable devices.

An output device is assigned to a software zone that contains no input devices.

This condition indicates the system is undergoing a reset process to clear latched alarms and troubles, reset power to 4-wire detectors, and perform a lamp test.

This condition indicates that a sensor or expansion module has been tampered with, typically involving the opening of a device enclosure or activation of a tamper switch.

The panel has detected a loss of voltage or failure on telephone line 1.

The panel has detected a loss of voltage or failure on telephone line 2.

The communicator has failed to report on all available telephone lines.

A failure occurred during a programming upload or download session.

A fault has been detected in the voice evacuation subsystem interface.

A condition indicating that water is flowing through the fire sprinkler system, typically detected by a monitor module or waterflow circuit.

A software zone has been manually disabled.
