key-removed is the closed position; it should be located inside the same backbox as the UDACT, as
close to the UDACT as possible.
Note: During testing when the key switch is turned, the panel will report a communication failure for
the UDACT’s address.

3.18 Installing Printers
This section contains information on connecting a printer to the CPU and for setting the printer options.
The basic steps are as follows:
1. Make custom cable & connect it from printer to EIA-232 terminal on the CPU.
2. Connect printer’s power supply.
3. Configure printer settings as described in printer documentation.
Overview: PRN Printer
The PRN provides a printed record (80 columns on standard 9" x 11"
tractor-feed paper) of all system events (alarm, trouble) and status changes
within the system. The control panel can be configured to time-stamp the
printout with the current time-of-day and date for each event. The printer
can be located up to 50 feet (15.25 m) from the control panel. Installation
and configuration instructions follow.
Overview: Keltron Remote Printer (Model VS4095)
The VS4095 is a two-color (red and black), 40-column, 24 VDC printer that can
print up to 50 messages in 90 seconds. This printer connects to the EIA-232 TB5
on the CPU and to the +24V screw on TB6 of AMPS-24/E, and mounts in a
separate cabinet next to the control panel. The VS4095 meets UL fire and
security requirements for an ancillary device; it is not ULC-listed. For more
information on the Keltron printer, contact the manufacturer (Keltron Corp.,
Waltham, MA). Installation and configuration instructions follow.
3.18.1 Printer Installation Sequence
1. Fabricate a custom cable to connect a printer 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. Using overall foil/braided-shield twisted-pair cable, properly
connect one end to the DB-25 Connector (provided) using the wiring specifications shown in
Figure 31.
2. Tighten clamp on connector to secure cable. Connect the four open leads of the custom cable to the
TB5 terminal block on the CPU as shown in Figure 31.
