GENERAL DESCRIPTION
The 41071 Alarm Display Unit provides audible and visual alarm indicators for Dantels 460 Alarm and Control System.
You can wire the unit for critical, major, and minor alarms. The
unit accepts up to 40 ground inputs from the 460 ACS equip-
ment. The inputs are arranged into three groups to activate the
different alarms.
Two red lamps on the front of the display box indicate critical
and major alarms, and an amber lamp indicates minor alarms.
All alarms also activate an audible alarm, which sounds when
the ON/ACO switch on the remote switch box is in the ON
position. You can change the alarm volume by adjusting a screw
on the right side of the display box.
When the ON/ACO switch is in the ACO (Alarm Cut-Off) posi-
tion, the audible alarm is disabled and the clear lamp lights on
the front of the display box.
A push button on the remote switch box tests the lamps and
audible alarm.
NOTE: This section lists the different options available for this product. To order any of the avail-
able options, contact Dantel Inside Sales through our toll-free number, 1-800-432-6835.

ORDERING INFORMATION

41071-1199<90-00037> PAGE 3
The schematic diagram for the 41071 Alarm Display Unit is shown in Fig. 1.
♦Ground alarm inputs are connected to the three relay coils,
K1, K2, and K3 through the two banks of isolation diodes.
♦When a relay is energized, the corresponding lamp lights and
the audible alarm sounds.
♦The audible alarm sounds when there is an alarm if the remote
ON/ACO switch is in the ON position. You can change the
alarm volume by adjusting a screw on the right side of the
display box. When the ON/ACO switch is in the ACO (Alarm
Cut-Off) position, the audible alarm is disabled and the clear
lamp lights on the front of the display box.
♦Each of the relays has a set of contacts for sending remote
alarms. A 500-ohm resistor (R5) is furnished to provide optional
strapping for any one of the relay outputs, if required.
♦A push button on the remote switch box tests the operation of
the lamps and audible alarm.

APPLICATION INFORMATION
T
he Alarm Display Unit can be installed wherever audible
and visual alarm indicators are needed (for example, at the end
of an equipment aisle).
The Alarm Display Unit consists of two parts:
♦The alarm display box
♦A remote switch box with a 12-foot cable
You can mount the display box at ceiling level and the switch box
at floor level.
The 41071 Alarm Display Unit can be used with the following
devices:
MULTIPLEALARM TRANSMITTERS(MATS):
Inputs to the Alarm Display Unit can come from the A through D
alarm level relay outputs from Dantels 46009 and 46010 Multiple
Alarm Transmitters (MATs). Refer to Fig. 2.

SUMMARYAUDIBLE ALARMMODULE:
You can tie alarm outputs from the relays of Dantels 46017
Summary Audible Alarm Module (SAAM) to the Alarm Display
Units inputs. The SAAM has two groups of alarms. Each group
has eight inputs but only one output. As a result, the SAAM can
accept only two levels of alarms, which can come from MATs or
Dantels 46020 Multiple Alarm Processor (MAP). To report all four
alarm levels (A, B, C, D) you need two SAAMs. Refer to
Fig. 3.
FIG.3 - TYPICAL RELAY CONNECTIONS, 46017SUMMARY AUDIBLE ALARM MODULE
SUMMARYALARM MODULE:
Dantels 46019 Summary Alarm Module (SAM) has four inputs to
accept the A-D alarm outputs of a MAP. The SAM relay outputs
are wired to the Alarm Display Units inputs. Refer to Fig. 4.

3. Wire the ground outputs.
Each relay is connected to a lamp to indicate an alarm level as
follows:
♦Refer to Fig. 7 for wire-wrap pin locations and Figs. 2-6 for
examples of how the wiring can be done.
♦Route the wiring through the large hole in the top of the dis-
play box.
♦Wire the ground outputs from the relays of the MATs, SAAMs,
SAMs, or CPMs that will be critical alarms to the anode side
(side of diodes with numbers beside them) of the lowest num-
bered diodes on the top and middle PCBs. For example, 12 criti-
cal alarms can be wired to pins 1 through 6 on each PCB.
♦Jumper the cathode (non-numbered) side of these diodes to-
gether.
♦Wire one cathode to K1A on the bottom PCB.
♦Wire the ground outputs from the relays of the MATs, SAAMs,
SAMs, or CPMs that will be major alarms to the anode side
(side of diodes with numbers beside them) of the middle diodes
on the top and middle PCBs.
♦Jumper the cathode (non-numbered) side of these diodes to-
gether.
♦Wire one cathode to K2A on the bottom PCB.
♦Wire the ground outputs from the relays of the MATs, SAAMs,
SAMs, or CPMs that will be minor alarms to the anode side
(side of diodes with numbers beside them) of the lowest num-
bered diodes on the top and middle PCBs.
♦Jumper the cathode (non-numbered) side of these diodes to-
gether.
♦Wire one cathode to K3A on the bottom PCB.
♦If you are using a 46029 CPM, install the relay jumper, on the
CPMs main board, in the IN position.
4. Wire relay pins to the battery.
♦Wire relay pins K1B, K2B, and K3B to the battery (-48V) pin.
Terminals K1C, K2C, and K3C are used when additional resis-
tance is required in the operating path of the relays.
5. Wire the relay outputs, if needed.
♦Wire pins 1, 2, and 3 of K1, K2, and K3 as needed for remote
alarm sending.
There are two pins labeled 500 ohms that are across a 500-ohm
resistor to provide optional strapping to limit the current of one of
the relay outputs, if required.
♦Wire the resistor, if needed, in series with the relay output.

6. Connect power.
Connect the power source (power off) to the display box:
♦Battery to the -48V pin through a one ampere fuse and ground
to the +48V pin.
7. Mount the display box.

mounting holes on the back or on the left side of the box. Use #
6 mounting hardware (not supplied).
♦Replace the cover on the display box.
8. Mount the switch box.
♦Remove the cover from the switch box and mount it, using the
mounting holes on the back Use #6 mounting hardware (not
supplied).
♦Replace the cover on the switch box.
CHECKOUT
To verify the operation of the 41071 Alarm Display Unit, follow
these steps.
1. Apply power to the unit. Make sure the ON/ACO switch on the
remote switch box is in the ON position.
2. Push the AUDIO-VISUAL TEST button on the remote switch
box.
In proper operation, the four lamps light, and the audible
alarm sounds. To adjust the volume of the audible alarm, turn
the screw on the right side of the alarm display box.
3. Cause an alarm on each input.
In proper operation, the appropriate lamp lights and the au-
dible alarm sounds.
4. To disable the audible alarm, put the ON/ACO switch in the
ACO position.
In proper operation, the audible alarm does not sound when an
alarm occurs.
LAMPREPLACEMENTPROCEDURE
To replace the lamps on the 41071 Alarm Display Unit, follow the
