Communication Options
Fax Modem Option (FAX)
The Computer Fax Modem is
an option that automatically
notifies the user of system test
results and alarm conditions.
This is accomplished by sending a detailed fax to up to six
preprogrammed phone numbers. Fax Modem can establish
communication via RS232 to perform any system function. The
Fax Modem Option is comprised of a single board computer
with factory-installed software, modem card and associated
cables.
The Fax Modem Option allows for remote monitoring via
modem connection, notification of alarm conditions by fax to
technical support and five additional fax machines, and faxed
reports of all UL 924-required system tests of the system.
Entire system is factory installed.
 ●
Requires customer supplied dedicated analog phone line
 ●
Fax machine phone numbers can be programmed locally
using the unit keypad or computer terminal or remotely
via modem. Numbers can also be programmed at time
of installation
The facsimile-modem automatically sends a fax to the numbers
programmed whenever:
 ●
The unit performs a monthly or annual system test
 ●
The unit sounds an alarm
Remote Status Panel (RSP)
The Remote Status Panel provides
remote annunciation for the Spectron
LSN to indicate inverter and alarm
status. The Remote Status Panel is
supplied in a 4-inch x 5
3
/
4
-inch electrical
box. It consists of five LEDs and an
alarm beeper.
Criteria for installation:
 ●
Must be installed within 1,000 feet of the Spectron LSN
 ●
Seven-conductor-minimum, 22AWG wire for connection
from options board to Remote Status
Panel must be
supplied by installer
System Monitoring Terminals (SMT)
The SMT option provides three functional terminal blocks:
 ●
Connection points for Inverter and Alarm relays. Low power
contacts change status with either inverter or alarm events.
 ●
Connection points for a Remote Status Panel to allow the
addition of an RSP at any time.
 ●
Connection points for an Emergency Power Off (EPO)
switch to allow for safe remote shut-down of system
regardless of operating mode.
Alternate Runtime (AR)
Runtimes other than the standard 90 minutes may be specified.
When ordering alternate runtimes, specify discharge time
required in minutes. Example: AR30
Short Battery Cabinet (SBC)
For applications where headroom is
limited, the Short Battery Cabinet (SBC)
can be used to reduce the overall
installation height by 15 inches. The
Short Battery Cabinet is available on
systems with ratings from 1.0kVA to
6.6kVA. Dimensions are 31” H x 30” W
x 18
5
/8” D.
Circuit Breaker Options
Output Circuit Breakers with Alarms
A maximum of 14 positions (20 positions without alarms) are
available for all models. Single pole, 120VAC and 277VAC
breakers occupy one position each. Double pole 240VAC
breakers occupy two positions each. See page 10 for ordering
information.
Normally-Off Output Circuit Breakers
Used when connected loads are to be energized only during
emergency inverter operation. Normally-off circuit breakers are
user programmable for a delay of up to 999 seconds. Single
pole, 120VAC and 277VAC breakers occupy one position each.
Double pole 240VAC breakers occupy two positions each. See
page 10 for ordering information.
Internal Bypass Switch (IBS)
The Internal Bypass Switch is a three-
position “make before break” service switch
mounted inside the cabinet. The IBS is
compatible with all input/output combinations
and works with any combination or quantity
of output circuit breakers.
Accessories
Multiplexer (MX)
The Multiplexer is an external device that enables a single
phone line to communicate with up to 16 Spectron LSN
units via their built-in RS232 communication ports. This is
accomplished by installing a phone line and FAX option in only
one of the systems to be monitored. Systems can be installed
up to 100 feet away from the Master without the use of Short
Haul Modems. The use of a Multiplexer reduces the number of
phone lines needed for remote communications, dramatically
reducing the cost.
Communications with the Multiplexer are identical to those of a
Fax Modem.
Short Haul Modem (SHM)
Short Haul Modems are devices that boost signal levels when
RS232 communications are installed more than 100 feet
away from Spectron LSN. One device is installed next to the
Spectron LSN and the other is installed next to the computer
communicating with Spectron LSN.
Maintenance Bypass Switches
The Maintenance Bypass Switch is a device that enables power
to be removed from the inverter system and remain connected
to the load. This allows the inverter system to be completely
removed, replaced or repaired without interruption to the load.
External Bypass Switch (MBB and
BBM)
The External Maintenance Bypass Switch
is supplied in a wall mounted, NEMA 1
type enclosure which cannot be used in
conjunction with more than one single-
pole output circuit breaker, on units with
dissimilar input and output voltages or on
models with mixed output voltages.

= Make-before-break
BBM = Break-before-make
