FOREWORD
A Word to the Owner of the BR-500
Congratulations on your choice of the FURUNO BR-500 Bridge Navigational Watch Alarm System
(BNWAS). We are confident you will see why the FURUNO name has become synonymous with
quality and reliability.
For over 60 years FURUNO Electric Company has enjoyed an enviable reputation for innovative
and dependable marine electronics equipment. This dedication to excellence is furthered by our
extensive global network of agents and dealers.
Your equipment is designed and constructed to meet the rigorous demands of the marine envi-
ronment. However, no machine can perform its intended function unless properly operated and
maintained. Please carefully read and follow the operation and maintenance procedures set forth
in this manual.
Thank you for considering and purchasing FURUNO.
We would appreciate feedback from you, the end-user, about whether we are achieving our pur-
poses.
Features
The BR-500 monitors the Officer of the Watch’s (OOW) presence on the bridge to prevent mari-
time casualties. The system sends an alarm to the quarters of the backup officer if the OOW fails
to respond to the active alarm or emergency call.
• Complies with IMO MSC.128(75).
• Watches for unattended bridge and operator disability.
• Transmits alarm to backup officer if the OOW fails to respond to active alarm or emergency call.
• Motion Detector (option) detects motion on the bridge to confirm operator fitness.
• Flash Beacon (option) flashes to remind OOW to confirm presence (by operating equipment in
the system).

Usage precautions
Back-up power supply
The BR-500 is not equipped with a back-up power supply. Use an external back-up power supply
(24 VDC) when the main or auxiliary power fails.
Motion Detector (BR-560)
zThe Motion Detector judges motion by the amount of temperature change within the detection
area. If the area has source(s) of heat other than personnel or the temperature change is too
small, detection of motion may not be possible. Keep the following points in mind:
Motion is mis-detected when
• movement in sleep is judged as motion.
• movement by small animal(s) is judged as motion.
• equipment that circulates air (air conditioner, etc.), steam-generating warmers and the like
causes temperature change.
• sunlight or shade in the detection area causes temperature change.
Motion cannot be detected if
• the temperature change in personnel or detection area is too small.
• personnel motion is too fast or too slow
• there is an impedance between personnel and the Motion Detector.
zThe Motion Detector can be affected by sunlight. Install it in a place well away from sunlight.
Alarm ACK signal
The BR-500 receives the Alarm ACK signal in contact signal format only. It cannot receive the sig-
nal in serial format.

1.7 Watch Alarm Sequence
The watch alarm checks for the presence of the OOW on the bridge. If equipment on
the bridge (Main Alarm Panel, Timer Reset Panel, Backup Navigator, Autopilot, or Mo-
tion Detector) is operated within the selected watch time interval, no alarm is given. If
no equipment is operated within the selected watch time interval, the system contin-
ues in the sequence shown below.
1. The watch alarm timer starts when the system is started. The length of the watch
time interval countdown timer bar (color is light-blue at this time) decreases as
time progresses. (The timer interval is set on the Administrator Menu, which is un-
der the control of the Administrator.)
If the equipment connected to the system is operated before the timer reaches
zero, the timer countdown is restarted.
2. If the equipment connected to the system is not operated within the watch time
interval, the PREWARNING phase begins:
• Main Alarm Panel shows a 15-second visual alarm (in yellow)
• Timer Reset Panel flashes its ALARM LED 15 seconds
• Flash Beacon flashes
