ALARM-UNIT AL8-2 船舶报警装置 探测回路故障

ALARM-UNIT AL8-2是一种船舶报警装置，其维修方法包括以下几种情况：
主电源故障：检查输入电源是否完好，检查熔丝有无烧断、接触不良等情况。
备用电源故障：检查充电装置、电池是否损坏，连线有无断线。
探测回路故障：检查该回路至火灾探测器的接线是否完好，有无火灾探测器被取下，终端监控器有无损坏。
误报火警：应勘察误报的火灾探测器的现场有无蒸气、粉尘等影响火灾探测器正常工作的环境干扰存在，如有干扰存在，则应设法排除。
不能与主机通讯：
线路未正确连接，需要重新连接线路并测试。
探测器地址重号或超过主机容量，需要排除重号后重新搜索。
设备损坏，需要更换设备。
通讯故障：
线路短路或断路，需要检查线路并排除短路或断路后重新进行通讯测试。
连接线松动，需要检查线路连接处是否有松动情况，排除后重新进行通讯测试。

ALARM-UNIT AL8-2

Alarm-unit AL8-2 is a ship ALARM device, and its maintenance methods include the following situations:
The main power supply is faulty: Check whether the input power supply is intact and whether the fuse is burned or in poor contact.
If the standby power supply is faulty, check whether the charging device and battery are damaged, and whether the cable is disconnected.
Detection loop failure: check whether the wiring between the loop and the fire detector is intact, whether the fire detector is removed, and whether the terminal monitor is damaged.
False fire alarm: should investigate the scene of the false alarm of the fire detector for steam, dust and other environmental interference affecting the normal operation of the fire detector, if there is interference, you should try to eliminate.
Cannot communicate with host:
The line is not connected correctly, you need to reconnect the line and test.
The probe address is heavy or exceeds the host capacity. You need to exclude the heavy number and search again.
The device is damaged and needs to be replaced.
Communication failure:
If the line is short circuited or broken, check the line and remove the short circuit or broken circuit before re-testing the communication.
If the connection line is loose, check whether there is any loosening at the connection point of the line. After the removal, conduct a communication test again.
The detector address is repeated, and the double sign must be excluded and searched again.
