ORDERING INFORMATION
GENERAL DESCRIPTION
The 41072 Aisle Pilot Alarm Unit provides 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 100 ground inputs from the 460 ACS equip-
ment. The inputs are arranged into four groups of 25 to activate
the different alarms.
Critical and major alarms are reported to a MAJ lamp on the
front of the unit. Minor alarms are reported to a MIN lamp on
the front of the unit. Critical, major, and minor alarms also can
be reported to external audible or visual indicating equipment.
Buttons on the front panel test the critical, major, and minor
alarm relays and external alarm indicating devices.
CIRCUIT DESCRIPTION
The schematic diagram for the 41072 Aisle Pilot Alarm Unit is
shown in Fig. 1.
♦Ground alarm inputs are connected to the three relay coils --
K1, K2, and K3 -- through the four banks of isolation diodes.
♦When a relay is energized, the corresponding lamp lights and
activates any external alarm indicating devices connected to
the unit.
♦Each of the relays has a set of contacts for sending remote
alarms.
♦The front panel test buttons provide grounds to operate the
relays and test the front panel lamps and any external alarm
indicating devices.
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.

APPLICATION INFORMATION
The Alarm Display Unit can be installed wherever audible alarm indicators are needed (for example, at the end of an
equipment aisle).
The 41072 Alarm Display Unit can be used with the following
devices:
MULTIPLE ALARM 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 the MAT Practice
for pin-outs.
SUMMARY AUDIBLE ALARM MODULE:
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 the
SAAM Practice for pin-outs.
SUMMARY ALARM 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
the SAM Practice for pin-outs.
CONTROL POINT MODULES:
Dantels 46028 and 46029 Control Point Modules (CPMs) can
echo alarms from MATs. If you use this application, you can
connect the outputs of the CPMs to the Alarm Display Units
inputs for alarm indication. Refer to the CPM Practice for pin-
outs.
STATUS MONITOR:
The audible and visual alarm outputs from Dantels 46001
Status Monitor can be wired to the Alarm Display Units inputs.
Refer to the Status Monitor Practice for pin-outs.

This section describes the steps necessary to install the 41072 Alarm Display Unit.
1. Open the cover.
Open the unit. The hinged access cover requires 3/8" of forward
movement, then a downward rotation of approximately 180
degrees.
2. Mount the unit.
Mount the unit using the four mounting holes in the rear of the
unit. Use #6 hardware (not supplied). If the A16-41076-00
mounting bracket is used, refer to the mounting bracket docu-
mentation.
3. Wire the ground inputs.
Refer to Fig. 2.
♦To facilitate the installation of the wire-wrap connections,
temporarily disconnect the connectors P1 and P2.
♦Route the wiring through the large hole in the top of the unit.
♦Wire the ground outputs from the relays of the MATs,
SAAMs, SAMs, or CPMs to the wire-wrap pin terminals on
the diode boards as required. Connect the alarm inputs to the
anode (+) sides of the diodes.
♦Jumper the cathode (-) sides of the diodes that are minor
alarms together.
♦Jumper the cathode (-) sides of the diodes that are major
alarms together.
♦Jumper the cathode (-) sides of the diodes that are critical
alarms together.
♦Wire-wrap the cathode side of the critical alarms to the first
terminal of P1. Wire-wrap the cathode side of the major
alarms to the second terminal of P1. Wire-wrap the cathode
side of the minor alarms to the third terminal of P1.
♦Reconnect P1 and P2.
4. Wire the relay pins to the battery.
♦Wire relay pins K1B, K2B, and K3B to the battery (-48VDC)
pin.
Terminals K1C, K2C, and K3C are used when additional
resistance is required in the operating path of the relays.
5. Wire the relay outputs, if needed.
♦Connect the external audible or visual alarm indicating de-
vices to P2.
♦The external devices must accept a ground input.
