General Network Alarm: Raise, Cancel, Mute
A general network alarm can be initiated from a Display Console and may be used to
alert the crew that there is a problem onboard a vessel.
Raising a General Alarm
1. Press and hold the ALARM button on the Display Console for 3 seconds.
While the button is being pressed the router emits up ramping tones and the
STROBE flashes quickly; or
2. Activate an external alarm system that has been wired to the Display
Console's switch input (i.e. press an emergency button).
When a general network alarm is activated the following events occur:
·
The STROBE on all active Tags starts to flash and the Tags start to vibrate.
·
The STROBE on the Display Console and any Internal Routers starts to flash
twice per second and the routers emit loud repetitive tones.
·
The STROBE on all External Routers starts to flash.
·
Any external safety or alarm warning systems that are attached to a router will
also be activated (when using factory default relay settings).
Network Mute/Acknowledgement of a General Alarm
Press the ALARM button on the Display Console. This mutes the general alarm
across the Crewsafe network.
Once muted:
·
The audio alarm is reduced to a single beep every 5 seconds on the Display
Console and Internal Routers.
·
Active Tags continue to vibrate.
·
The STROBE light on all routers and Tags will stop flashing, so that night
vision is not affected.
