6.1. GENERAL ALARM I
NTERFACE TO SHIPS WHISTLE / SIREN
In order to use the ships whistle as a part of the General Alarm system the MPA 1600 is providing a
dry closing contact (NO) output that generates a control output signal synchronised with the GA tone
sequence. Ref. document 03118-025-EC.
6.2. MUTE OF EXTERNAL GENERAL ALARM DURING EMERGENCY PA
During an active Emergency PA the MPA 1600 outputs a dry closing contact (NO) output as a mute
signal for an alternative external GA system. This signal is activated together with the internal GA
mute functionality.
Ref. documents: Ref. documents 03118-025-EC and 03118-000-OP, Section 2 (OPERATING
DESCRIPTION) / Chapter 2.1 (Emergency Paging)
6.3. GENERAL ALARM WARNING (FLASHING) LIGHT
An active General Alarm in the MPA 1600 system is also indicated with a dry closing contact (NO)
output for activation of external GA warning lights. This is mandatory in high noise environments.
Ref. document 03118-025-EC.
6.4. ENTERTAINMENT MUTE, PA/GA
In case the MPA 1600 system has integrated entertainment functionality or this is an external system
this is of very low priority and shall be muted during GA and Emergency PA. The internal MPA 1600
mute functionality is working together with a dry closing contact (NO) output for external use.
Ref. documents:
- 03118-000-OP, Section 2 (OPERATING DESCRIPTION) / Chapter 2.1 (Emergency Paging)
- 03118-000-OP, Section 2 (OPERATING DESCRIPTION) / Chapter 2.3 (Alarm)
- 03118-025-EC
6.5. VOLUME OVERRIDE
In addition to the entertainment mute functionality, the MPA 1600 is equipped with a volume override
signal as a relay driver output (Open Collector source/sink) which is activated during both GA and
Emergency PA. This signal is used for resetting local entertainment (etc.) volume control settings
related to the GA/PA system.
Ref. documents:
- 03118-000-OP, Section 2 (OPERATING DESCRIPTION) / Chapter 2.1 (Emergency Paging)
- 03118-000-OP, Section 2 (OPERATING DESCRIPTION) / Chapter 2.3 (Alarm)
- 03118-025-EC
6.6. POWER FAILURE
The MPA 1600 is supplied from two different sources: primary and backup. The system is equipped
with a dry closing contact (NO & NC) output that is activated whenever one of these sources fail,
either primary or backup. This signal can either be used as an interface to external surveillance and
monitoring systems or for direct signals, as rotating/flashing lights or light columns.
Ref. document 03118-025-EC.
