Dantel 46210 User manual

CAUTION
•Install or remove modules from the shelf only when the power is off.
If you install a module in the shelf with the power on, the internal
circuitry may suffer damage and the product warranty will be void.
•Remove and install circuit boards only in a static-safe environment
(use antistatic wrist straps, smocks, footwear, etc.).
•Keep circuit boards in their antistatic bags when they are not in use.
•Do not ship or store circuit boards near strong electrostatic, electromag-
netic, magnetic, or radioactive fields.
•For more complete information on electrostatic discharge safety
precautions, refer to BellcoreTM Technical Reference # TR-NWT-000870.

ORDERING INFORMATION
GENERAL DESCRIPTION
The 46210-00 Alarm Block and 46220 Alarm and Control Block are available in three options. Refer to the Ordering
Information section above.
Ground signals activate the alarm inputs. The units convert
alarm information into TBOS, DCP, DCPF, or DCM protocol and
send it to alarm reporting equipment. Printer Syntax is also
available for maintenance purposes.
CIRCUIT DESCRIPTION
The 46210/46220 Alarm and Control Block functional sche- matic is shown in Fig. 1.
The microprocessor converts alarm and control information to
TBOS, DCP, DCPF, DCM, or Printer Syntax protocol. The
information is sent and received through the UART (Universal
Asynchronous Receiver/Transmitter) and the master and auxil-
iary ports.
A watchdog circuit resets the microprocessor if it malfunctions
temporarily.
Switches on the unit select the following:
♦Data rate (baud)
♦Method of alarm reporting
♦Protocol
♦TBOS display size
♦Beginning TBOS display
♦DCP, DCPF, or DCM address
♦Length of time for operating relays
WARNING:
When connecting or removing
the quick-disconnect power plug
to any Smart Block, it is neces-
sary to ensure that there is no
power present at the plug itself.
Remove power at either the cir-
cuit/bay fuse or remove the fuse
from the Smart Block itself be-
fore connecting the power plug.
Failure to do so will cause dam-
age to the Smart Block and may
void any Dantel warranty.
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.

LEDs indicate:
♦If the unit is transmitting or receiving data through the mas-
ter or auxiliary ports,
♦If the microprocessor is operating,
♦If the power is on,
♦If the power fuse has blown.
The unit operates on -21 to -56 VDC.
In addition to the fuse failure LED, an external light or bell can
be connected to the power supply to indicate fuse failure.

NOTE: When the unit is used without an optional
communications subassembly, the auxiliary port has an
RS-422 interface and the master port has an RS-422/485
interface. When the unit communicates via an optional
communications subassembly, the port with the subassembly
installed becomes the master port and the auxiliary port
communicates via an RS-422/485 interface. The auxiliary
port with the RS-422 interface only is not used.

When using DCM protocol, the starting address set with switch
S1 determines the addresses for all the alarm points on the
block. Sixteen alarm points are assigned to each address. There-
fore, the 46210 Alarm Block, which has 256 alarm points,
requires 16 addresses (16 x 16 = 256). If the starting address is
17, the DCM addressing for a 256-point block would be ad-
dresses 17 through 32. The following table shows the number of
addresses required for each type of block.

The highest address that can be used is 128, which is a limita-
tion of the DCM protocol. Thus, the highest starting address for
a 256-point block would be 113 (113 through 128 = 16 ad-
dresses). If an address higher than 113 is used, addresses above
128 will not be polled. The following table shows the highest
starting address for each type of block.

The same starting address that is used for alarms also is used
for controls. The 46220-01 has 16 controls. If the starting ad-
dress of the block is 17, then the address for controls on a
46220-01 would be 17. The 46220-00 has 32 controls. If the
starting address of the block is 17, then the addresses for the
controls on a 46220-00 would be 17 and 18. The 46210 does not
have any controls.

Wire the power, alarm inputs, control outputs, and the commu-
nications ports as described below. Connector P1 is not used.
1. On the power supply board, wire negative battery (-21 to -56 VDC)
and ground to connector TB1 (refer to Fig. 13). Remove the connec-
tor for easier access. Do not turn on the power until instructed.
2. Wire an external fuse alarm indicating device, such as a light or
bell, to the ALM output of TB1 (optional). When the fuse fails, the
external device operates as well as the ALARM LED on the front
panel.
3. Push the power supply and CPU boards back into place and close
the unit.

4. Open the plastic cover (refer to Fig. 14).
5. Wire the alarm inputs (refer to Fig. 15 or the template inside the
plastic cover).
There are two pins for each alarm input. One is for ground and the
other is for the alarm input. The dark-colored columns are grounds
and are wired together. Wire one of the ground pins to signal
ground on your equipment.
Leave enough slack in the wires to open the unit easily.

6. Wire the control outputs of any 46220 units (refer to Fig. 15 or the
template inside the plastic cover).
There are two pins for each normally open relay. Wire the pins for
either a battery or ground output when the relays are closed. Pin
pairs for the relays are A-B, C-D, E-F, G-H, J-K, L-M, N-P, and
R-S.
7. Wire the master and/or auxiliary ports at column 32 (refer to
Fig. 15 or the template inside the plastic cover).
If no communications subassembly is used, pins A-D are the auxil-
iary port connections and pins E-H are the master port connec-
tions.
If an RS-232 or 202 Tone Modem subassembly, pins E-H are the
auxiliary port connections and pins J-S are the master port connec-
tions.
To wire to a Digital Alarm Scanner (DAS) unit, refer to Fig. 16.
