Type 8001



The type 8001 Alarm Annunciator is designed specifically for the marine industry. It is a compact, solid state alarm panel for operation with digital (on-off) sensors. Operating voltage is 12VDC through 32VDC nominal, direct from ships batteries or from regulated power supplies.

Highly visible engraved displays offer a large white engraving surface which becomes a brilliant red when turned on.

Either 16 or 32 alarm points are provided per alarm annunciator. The 32 point annunciator has backlit displays sized 0.85"(22 mm) x 2.5"(63 mm). The 16 point annunciator has backlit displays sized 1.85"(47 mm) x 2.5"(63 mm). Computerized dimming control is provided. The dimmer has been designed to be very adjustable in the low intensity region for greater control at night on the bridge.

The lenses are front removable without tools. The fuse is accessible from the rear of the annunciator. All PC boards have computer generated artwork, and are cleaned, conformal coated and tested prior to shipment.


Remote fault contacts may be normally open (close on fault) or normally closed (open on fault). Also, using an optional end of line resistor, open circuits, line shorts and status changes can be detected. Annunciation of each fault is delayed by an adjustable time period of 1/2 through 99 seconds. Any fault which persists longer than the set time delay is captured until acknowledged. Automatic reset occurs after the fault has been acknowledged and is corrected.

The front display will flash for new faults until acknowledged and will remain on steady while the fault persists. Individual alarm points can be programmed such that their displays do not revert to steady after acknowledgment. This feature can be used to emphasize the critical alarm points.

Faults can be programmed to turn on the internal horn, internal Semi-Essential alarm relay, internal Essential alarm relay, or a secondary open collector output for each alarm point. Individual alarm points can be programmed to turn all, some or none of these devices. The Semi-Essential and Essential relays can be used to control external audible and visual devices.

The Silence button is used to deactivate the external alarms and the internal horn. The Acknowledge button performs the same function as the silence button and also causes the alarm display to change from flashing to steady. If silenced first, the alarm display will continue to flash until it is acknowledged. When a new fault occurs, the silence pushbutton restarts to flash to provide a quick visual indication of which enclosure is annunciating the alarm in multiple annunciator installations.

A test pushbutton is provided which, while it is pressed, will insert a fictitious fault into the input of all points. Internal time delays are also checked by pushing the button. Testing may occur at any time without altering the status of existing alarm displays.

Field Programmable Features

Additional features which are included as standard, and which may be field programmed, include:

The 8001 Alarm annunciator comes complete with an RS-232C or RS-485 serial port for communication with remote computers or alarm repeaters and a Centronics compatible printer port for a log printer.

All programming is done through the rear mounted display. The annunciator is easily programmed through this display and is designed to stand alone, or can be configured to work with a group of alarm panels.


Additional equipment is available to complete the alarm system including: remote group alarm repeaters, single point displays, cabin repeaters, watch keeping systems, air horns, overload alarms, electric horns, rotating beacons, bells, etc.

A repeater panel specifically designed to repeat alarms or groups of alarms from 8001 Alarm Annunciators is available. The Type 8101 Alarm Repeater is based on the 8001 Alarm Annunciator. Up to eight 8001 alarm panels and eight 8101 alarm repeater panels can communicate over a single two wire bus. Using the RS-485 communication standard in the multidrop configuration, transmission distances are up to 4000 feet.
