DTC-300A DACT Dialer Installation and Operation Instructions
Industry Canada and FCC Notice
Notice for all DTC-300A Sold in the U.S.A.
Note: The Ringer Equivalence Number (REN) for this product is X.X.
Mircom's DTC-300A Digital Communicator described in this manual is listed by Underwriters Laboratories Inc.
(ULI) under Standard 864 (Control Units for Fire Protective Signalling Systems). These Communicators comply with
the National Fire Protection Association (NFPA) performance requirements for DACTs and should be installed in
accordance with NFPA 72 Chapter 4 (Supervising Station Fire Alarm System). These Communicators should be
installed in accordance with this manual; the National Electrical Code (NFPA 70); and/or the local Authority Having
Jurisdiction (AHJ).
FCC Notice
This equipment complies with the Federal Communications Commission (FCC) rules and regulations governing
telephone equipment and the Technical Requirements for Connection to the Telephone Network published by the
industry’s Administrative Council for Terminal Attachments (ACTA). On the door of this equipment is a label that
contains, among other information, a product identifier in the format US:XXXXXXXXDTC-300A. If requested, this
number must be provided to the telephone company. This equipment is capable of seizing the line. This capability is
provided in the hardware.
The Ringer Equivalence Number (REN) assigned to each terminal device provides an indication of the maximum
number of devices that may be connected to a telephone line. Excessive REN’s on a telephone line may result in
the devices not ringing in response to an incoming call. In most, but not all areas, the sum of REN’s should not
exceed five (5.0). To be certain of the number of devices that may be connected to a line, as determined by the
total REN’s contact the local telephone company. The REN for this product is X.X.
Telephone Company Procedures: The goal of the telephone company is to provide you with the best service it
can. In order to do this, it may occasionally be necessary for them to make changes in their equipment, operations
or procedures. If these changes might affect your service or the operation of your equipment, the telephone
company will give you notice, in writing, to allow you to make any changes necessary to maintain uninterrupted
service.
In certain circumstances, it may be necessary for the telephone company to request information from you
concerning the equipment which you have connected to your telephone line. Upon request of the telephone
company, provide the FCC registration number and the ringer equivalence number (REN); both of these items are
listed on the equipment label. The sum of all of the REN’s on your telephone lines should be less than five in order
to assure proper service from the telephone company. In some cases, a sum of five may not be usable on a given
line.
If Problems Arise: If any of your telephone equipment is not operating properly, you should immediately remove it
from your telephone line, as it may cause harm to the telephone network. If the telephone company notes a
problem, they may temporarily discontinue service. When practical, they will notify you in advance of this
disconnection. If advance notice is not feasible, you will be notified as soon as possible. When you are notified, you
will be given the opportunity to correct the problem and informed of your right to file a complaint with the FCC.
Contact your telephone company if you have any questions about your phone line. In the event repairs are ever
needed on the Communicator, they should be performed by Mircom Technologies Ltd. or an authorized
representative of Mircom Technologies Ltd. For information contact Mircom Technologies Ltd. at the address and
phone numbers shown on the back page of this document.

Introduction and Features
Introduction and Features
The DTC-300A is a single board Digital Communicator (DACT) that can connect to any Fire Alarm Control Panel
(FACP). It can transmit Alarm, Supervisory, Waterflow Alarm, Common Trouble, AC power trouble and Battery
Trouble information on two telephone lines to a Digital Alarm Communicator Receiver (DACR).
Features:
• Scans up to 6 configurable input zones. The input zone type may be alarm, waterflow alarm, supervisory,
trouble, AC trouble or Battery trouble.
• Reports to a DACR using Ademco Contact ID or SIA DCS reporting protocols.
• The DTC-300A has the ability of disconnecting the incoming and outgoing calls and capturing the line for
transmission to the DACR.
• Provides telephone line monitoring and reports status via LED indication on-board.
• Provides LED indication for AC Power, Common Trouble, CPU Fail and Ground Fault.
• User configurable locally with on-board keypad and a CFG-300 Configuration Tool or using a UIMA and
computer with serial port or USB. Remotely configurable via a personal computer, modem and telephone line
connection.
• Provides event logs of 500 entries each to save events from local dialer or remote fire alarm panel. These logs
can be reviewed locally with the CFG-300 Configuration Tool or remotely via modem.
• Requires 24V DC filtered or 24V DC Full Wave Rectified (FWR) power supply.

Connections and Settings
DTC-300A MAIN BOARD
There are FOUR jumpers on the DTC-300A for operation/configuration purposes and 8 LEDs for status indication.
Jumper JW1 is used to reset the default passcode. Jumper JW2 is required for configuring
JW3 is used for enabling/disabling Ground Fault detection and JW4 is used to set the Trouble Relay. Refer to
Figure 2 for the location of jumpers, cable connections, pushbutton and LEDs. Table 1 provides a description of the
status LEDs on the DTC-300A and Table 2 provides information on the use of jumpers JW1 to JW4.

Table 2: DTC-300A List of Jumpers for Operation and Configuration
JUMPER NUMBER JUMPER FUNCTIONS
RESET PASSCODE: Default is normally open. TO RESET PASSCODE: Place
JW1
jumper here and power down the DTC-300A by disconnecting the 24V power source
or power down the fire alarm panel (AC and Batteries), then power back up to revert to
the default passcode. After the passcode is reset, remove the jumper.
JW2
JW3
JW4
BLOCK REMOTE CONFIGURATION: Default is normally open to BLOCK remote
configuration via modem, PC with a UIMA converter module or using the LCD and
keypad at the DTC-300A. A trouble is initiated when the jumper is ON showing that
the DTC-300A is in configuration mode. Place jumper here to ALLOW any type of
configuration. Remove jumper once configuration is complete, trouble will restore.
GROUND FAULT DETECTION: Default has jumper pins normally shorted allowing
ground fault detection on the DTC-300A. Remove this jumper to DISABLE ground
fault detection (Ground Fault LED on the DTC-300A will not operate). The Fire Alarm
Panel Ground Fault is not affected.
TROUBLE RELAY: Short pins 1 and 2 to select the TROUBLE OUTPUT relay
contacts as normally closed(N.C.) or short pins 2 and 3 to select the TROUBLE
OUTPUT relay contacts as normally open (N.O.). Default has pins 2 and 3 shorted,
check fire alarm panel for proper setting required for the TROUBLE OUTPUT
contacts.

DTC-300A MAIN BOARD INPUT ZONE WIRING
There are terminals for six input zones. Zones 1 to 6 are configurable. The default zone settings are as follows:
Table 3: Zone Default Functions
ZONE DEFAULT FUNCTION
Z1 Common Alarm Input
Z2 Common Supervisory Input
Z3 Common Trouble Input
Z4 Waterflow Alarm
Z5 AC Power Trouble Input
Z6 Battery Trouble Input
Input zones 1 through 6 can be connected to the form C relay contact outputs of an associated Fire Alarm panel.
These relay outputs show the status of the Fire Alarm panel as Alarm, Supervisory, Waterflow Alarm, Common
Trouble, AC Power Fail Trouble and Battery Trouble. Each input zone is supervised by an 820 ohms End of Line
Resistor or equivalent MP-820R/W which is a resistor on a white or red plate.

Notes:
• Maximum loop resistance should not exceed 100 ohms.
• Maximum capacitance of 0.5uF total on each zone.
TROUBLE OUTPUT WIRING
The trouble output is wired to a Fire Alarm Trouble Only monitor zone. This is done to monitor the DTC-300A. The
E.O.L resistor required for this zone is to be placed on the terminals marked E.O.L. below the Trouble Output. The
value of the E.O.L. resistor depends on the FACP used. For the Mircom FACP, use 3K9 ohms. The Trouble Output
terminals are dry contacts. Use JW4 to select either normally closed (pins 1 and 2) or normally open (pins 2 and 3).
