General Emergency Alarm System
General emergency alarm system, complies with the latest regulations and rules of CCS and SOLAS is designed for the distribution of optical and acoustical alarm signal of the general alarm and can be connected with the PA system which makes the alarm signal covers the whole vessel through the loudspeaker. The system controller adopted with a large scale of IC and micro-processing technology can distributes many kinds of alarm signals.
Overview
Features
Dimming function
power-failure alarm
alarm priority control
When being interrupted by the public radio, the board have actions to avoid an permanent interruption.
Typical signals
G/A signal:
7 short pluses followed by a long pulse
Short pulse:1S±0.1S
Long pulse:5S±0.5S
Manual Alarm signal: output based on the switch on or off
Fire alarm: continuous frequency modulation signal
Input interface
The GENERAL EMER. ALARM and MANUAL ALARM switch on the alarm panel. It also can connect button.
Output interface
Alarm bell output are normal open contacts without voltage. The large current contact can be provided according to the users' requirement.
PA: alarm audio signal to all speaker spread over the vessel through the PA system.
E/R alarm indicator column: the alarm signal extend to E/R, and the outputs are normal open contacts without voltage.
Fog horn control panel: control the fog horn to send signals according to tone. Outputs are normal open contacts without voltage.
Entertainment device interface: during alarm, close the entertainment device; outputs are normal open contacts without voltage
(Note: capacity of the output contractors are AC250V/1.5A or DC24V/1,5A)
Technical parameters
Power supply: DC24V±30%/20%, AC220V, 200mA(not include bell current)
Mounting size: 126×222(mm)
Flush type: 124×210×86(mm)
