3.8.3 Field Wiring an Auxiliary Relay Module
The figure above shows terminal assignments for ARM-4 module control relays K1-K4, which
control nonpower-limited circuits. Power-limited and nonpower-limited circuit wiring must remain
separated by at least 0.25 inch (6.35 mm) within the cabinet and exit the cabinet though different
knockouts, conduits, or both.
Note: For more information, refer to Section 3.6 “UL Power-limited Wiring Requirements”.
The table contains contact ratings for relays K1-K4 on the ARM-4 module:
3.9 Installing Remote Printers and/or CRT
3.9.1 Custom Cable Fabrication
A custom cable needs to be fabricated to connect the PRN-5 Printer, Keltron Printer or the CRT-2
Monitor to the system. Length of the cable will vary with each installation, but should not exceed a
maximum length of 50 feet (15.24 meters). Printer must be installed in the same room as panel.
Construct cable as follows:
1. Using overall foil/braided-shield twisted-pair cable, properly connect one end to the DB-25
Connector using the wiring specifications shown in the table below. (Custom cable kit P/N
90106 is provided.)
2. Tighten clamp on connector to secure cable.
3.9.2 Installing and Configuring the PRN-5 Printer
When connected to the Control Panel via an EIA-232 interface, the PRN-5 prints a copy of all
status changes within the control panel and time-stamps the printout with the time of day and date
the event occurred. It provides 80 columns of data on standard 9" by 11" tractor-feed paper.
Note: You can also use the EIA-232 printer interface with UL-listed I.T.E. equipment, such as
personal computers, to monitor the control panel for supplementary purposes.
This section contains information on connecting a printer to the control panel and for setting the
printer options.
Connecting a Remote PRN Printer
Remote printers require a 120 VAC, 50/60 Hz primary power source. If required for the fire alarm
system configuration (for example, a Proprietary Fire Alarm System), a remote printer requires a
secondary power source (battery backup). Because a secondary power source is not provided, use a
separate Uninterruptable Power Supply (UPS) that is UL-listed for Fire Protective Signaling. You
