CDR-3 Bell Coder
PRODUCT DESCRIPTION
SPECIFICATIONS
The CDR-3 Coder is a microcomputer-based module that provides
coded outputs in response to alarm conditions. The CDR-3 is used with
systems that require either march time, temporal, or unique coded
outputs for separate zones. The CDR-3 decodes alarm codes
embedded in printer messages that it receives through its RS-232
input.

WARNINGS
INSTALLATION INSTRUCTIONS
This module will NOT operate without electrical power. As fires
frequently cause power interruption, we suggest you discuss further
safeguards with your local fire protection specialist.
Disconnect power before installing or removing the module.
Dangerous voltages may be present at terminals even when power
is disconnected.
NOTES
If a printer and a CDR-3 are connected to the system:
Program both devices as enabled.
•
•
•
Connect both devices in parallel or to separate ports (if available).
Program the same baud rate for both devices when they share the
same port.

To mount the CDR-3:
1. Secure the plastic spacers to back of the main board with the
screws and washers provided.
2. Snap the main board onto the snap-top standoffs of any half
footprint in the enclosure.
Note: Mount the CDR-3 so that its terminal blocks do not face the corner
of the enclosure. Terminal blocks must face out for wiring to be installed
and removed easily.

1/4 inch (6.4 mm)
Strip 1/4 inch from the ends of ALL wires that connect to the terminal
blocks of the module.
Exposing than 1/4 inch of wire may cause a ground fault.
Exposing than 1/4 inch of wire may result in a faulty connection.
