3 . General AHD 0H is a group alarm and display unit for 0 groups and is mainly used on vessels (bridge). It has three serial inputs over which it can register individual reports per channel, which is reports altogether. Every report can address between zero and two groups. Every group can be programmed as alarm or display. Six subgroup relays with floating transfer contacts are available for control purposes. Each of these relays can be assigned (arbitrarily programmable) to the ten groups, as far as these are designated as alarms. The unit has two serial outputs to address the engineer- and messroom-control-panels. Additionally, it has a further serial output to control a printer.. Construction AHD 0H consists of two electronic cards which are connected by stay-rods. Together with the front panel, they form a plug-in unit. This plug-in unit is located in a housing for switchboard mounting according to DIN 00. It has front dimensions of mm x mm and an installation depth of mm. A 0-pole terminal block that can be mounted on TS or TS and a ribbon cable as plug-in connection between device and terminal block are part of the delivery. The front panel is available in the following two versions (see illustration on page of this description): - with individual LEDs and slide-in text field for illuminated rooms - with surface LEDs and text field as film-negative, e. g. for bridges on vessels.0 Function. Data registration AHD 0H registers the data over three serial inputs. As a source, among others, the following devices are possible: - alarm and monitoring system COMPACT EDA - data distributor AHD W - alarm and safety system AHD A The device receives the data according to the following serial protocol: Startbit (high), data bits out of which the high-bits can be grouped, control bits for serial acknowledgement, 0 to 00 bit stop (low). There are no start- or stop-bits during the transmission. The data rate is 00 baud. There are reasons for this unusual serial format which cannot be explained in detail here. However, it is possible to configure the software if necessary. Entering is done over optocouplers.. Grouping The device has an Eprom C or EEprom C, where the system-program and an area for the systemspecific programming are located. If a print-function is also required, an EPROM C is used, as in this case additional storage space for the texts is necessary. For grouping, further definition of the groups and sub-group relays, there are address fields on page of this description (system-specific programming). For access to the EPROM or EEPROM, the plug-in unit has to be torn out of the housing, after loosening the housing-frame and the fixing screw. The storage is located on the upper card and can be torn out of the IC-socket for programming.. Alarms/Displays Each group can be programmed as alarm or display. An alarm causes flashing of the corresponding measuring point. Simultaneously, the horn and collective alarm relay switch, and, as far as programmed,

Up to three COMPACT EDA can be connected to one group panel. control bits for serial acknowledgement 0 to 00 bit pause (low) Connection to further devices These inputs are usually not needed, as acknowledgement is done serially or over keys in the front panel.. Acoustic acknowledgement The horn relay can be reset with a key in the front panel or over a corresponding input at the terminal block. Furthermore, the horn relay can be acknowledged serially. If the group panel receives its data e. g. from the COMPACT EDA or from the data distributor AHD W, acknowledgement signals are transmitted serially from there, too.

5 . Visual acknowledgement A flashing measuring point changes to steady light by visual acknowledgement. This is also done with a key in the front panel or an input at the terminal block. Serial visual acknowledgement is also possible, which is done, e. g., by COMPACT EDA or the data distributor AHD W.. Repeated addressing of a group A group is usually a combination of several individual reports. In the event of an alarm, a group report that is already active but also acknowledged, is activated again, so that one individual report will not block the remaining alarms of the same group.. Lamp test The key for visual acknowledgement in the front panel of the device has also the function lamp test. All measuring points shine while it is pushed.. Collective alarm and subgroup relays Every alarm also causes switching of the collective alarm relay. In the event of a second alarm, the relay switches into normal position (closed) for app. s and then opens again (collective alarm repetition). A subgroup relay can be assigned to every measuring point, as far as it is programmed as alarm. If several measuring points have an effect on one relay, this relay can operate as first value indicator or, like the collective alarm relay, as new value indicator.. Call engineer If an alarm is not acknowledged acoustically in the engine control room within minutes (and thus serially the group panel, too), the relay CALL ALL ENG. switches. It is led to the 0-pole terminal block as normally-closed-contact and is reset after acknowledgement. In case chamber-/mess-room panels, within the scope of a st.-by alarm system, are connected to the device, this report will be activated there (serially), too..0 System failure AHD 0H has a relay that, under normal circumstances, has switched. The contact that leads to the terminal block is closed. In case of system failure or power failure the contact opens.. Dimming of display elements The construction of the device with a text field illuminated by surface LEDs, has a photo resistor by which the lucency of the LED is dimmed automatically depending on the ambient brightness. The maximal dimming at darkness can also be adjusted with a potentiometer in the front panel. Thus, dazzling or reflecting in the windowpanes is avoided.

Every individual report can be assigned aribtrarily to 0 to groups. The groups can be defined as alarms (flash, horn relay switches) or displays. Additionally, subgroups are available of which each can be assigned to any group displayed in the front panel. If an alarm group is not acknowledged for more than minutes, the relay CALL ALL ENG. switches. A storage area for the texts to be printed ( measuring points with characters each) is located in the EEprom (tear out insertion).
