NOTE
This equipment has been tested and found to
comply with the limits for a Class A digital device,
pursuant to part 15 of the FCC rules. These limits
are designed to provide reasonable protection
against harmful interference when the equipment is
operated in a commercial environment. This
equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in
accordance with the instruction manual, may cause
harmful interference to radio communications.
Operation of this equipment in a residential area is
likely to cause harmful interference in which case
the user will be required to correct the interference
at his own expense.
Section 1: INTRODUCTION
The Liebert RCM8CE and RCM8DO Remote Contact Monitors
Contact Liebert Environmental
Service & Support at
800-543-2778 regarding
installation, operation, or
warranty issues.
annunciate alarms by monitoring eight contact-closure points,
each point wired directly to the RCM8.
When the RCM8 receives an alarm signal, a piezoelectric siren
sounds and the LED illuminates for the corresponding contact
point (1 through 8). A text interface to a video terminal or PC
emulating a terminal session is used to configure the operating
parameters, and can remain connected to receive userprogrammed alarms messages.
In addition to monitoring alarm signals from locally-connected
equipment, the RCM8 can also dial out via modem to: remote
computer; another RCM8 acting as a repeater; numeric pager; or
alphanumeric pager. The RCM8DO features 8 additional
contact-closure outputs that mimic the state of the alarm LEDs.
Up to four RCM8 units can be connected in a local, multi-point
monitoring configuration. This gives added flexibility to monitor
up to 32 contact points. The RCM8 also communicates with the
Liebert SiteScan centralized monitoring system.

Display and Controls
Environmental Conditions:
Operating Temp: 5°C to 40°C
Operating Relative Humidity: 0%-95% (non-condensing)
Operating Altitude: up to 2,000 meters
Pollution Degree: 2
Enclosure Type: NEMA 1 (for indoor use only)
Enclosure Protection: IP30 (protection against solid foreign
objects 2.5mm or greater, no protection from water)
Alarm LEDs (Red)
For all unit configurations except Master Repeater units, each
alarm LED corresponds to an input and illuminates on alarm
(after the programmable alarm delay expires). For Master
Repeaters, its LEDs illuminate with the corresponding alarm
point from the unit in alarm: ie, Master Repeater alarm 1 will
illuminate when any of points 1, 9, 17 or 25 is in alarm. When a
connected unit goes off-line from the EIA-485 bus, all eight
LEDs flash, indicating a problem.
You can disable the audible
beeper by removing the P1
connector on the RCM8
circuit board. See Figure 3
in Chapter 2.
2 • User Manual (7/99)
Normal LED (Green)
When input power is OK, the Normal LED illuminates (solid). If
the RCM8 is running on the NiCad backup battery, the Normal
LED blinks.
Audible Alarm
When any alarm is active, an audible alarm sounds. If alarms are
non-latching (not requiring acknowledgment to reset), the beeper
stops when the alarm situation no longer exists. If the alarm is
latching, the beeper continues to sound until an operator
acknowledges the alarm condition and resets the beeper.
Silence/Reset Switch
The Silence/Reset switch turns OFF the audible alarm. If DIP
Switch SW1-8 is ON, the common alarm relay output will reset
with the Silence/Reset switch.
ON/OFF Switch
The RCM8 has a power ON/OFF switch located inside the
enclosure. Refer to Figure 1 below. When wiring the dry contact
connections, this switch should be in the OFF position. For
normal operation, the switch should be in the ON position.

Communications Ports
The RCM8 has five physical connection ports:
Refer to Chapter 2 of this
manual and the section
immediately following for
information on installation and
configuration using these
communications ports.
Common Alarm Relay
Output
• EIA-232 (PC/Terminal) Port (DCE)—Accommodates a
personal computer or VDT for setup and message display
• EIA-232 Modem Port (DTE)—Accommodates a modem
for alarm reception and remote message transmission
• EIA-485 Port—Allows multiple RCM8 units to be "daisy-
chained" together using twisted-pair wires
• EIA-422 SiteScan Port—Accommodates a Liebert
SiteScan connection
• Common Alarm Relay Output—Accommodates a
secondary warning device
Refer to Figure 1 Component Arrangement, and Figure 3
Physical Connections and DIP Switches.
The common alarm relay output is used to connect to a
secondary warning device -- such as a horn or light, up to 3
Ampere @ 24 Volts DC -- that activates on alarm. When an
alarm is present, the contacts close and the external warning
device is activated. The common alarm relay may be reset using
the Silence/Reset switch.
Alarm Relay Outputs
(RCM8DO only)
4 • User Manual (7/99)
On RCM8DO models, one relay output corresponding to each
alarm channel is provided. There is no additional programming
logic or setup involved: each Form-A Normally Open (N.O.)
relay will energize when the corresponding channel goes into
alarm and the front panel LED is illuminated. The relays are
rated for up to 1 Ampere @ 24Volts DC.
Section 2: Installation
Unpacking and
Inspection
This section describes the installation procedure for monitoring
systems using the RCM8. Installation includes:
• Unpacking and Inspection
• Mounting the RCM8 at the designated site
• Making RCM8 physical connections based on application
needs
• Configuring the modem
Inspect the package when delivered by the freight carrier. If the
shipping container is damaged, check for internal damage and
file a claim with the carrier if necessary. If the container is
undamaged, unpack the RCM8 and inspect it for obvious
damage. If it is necessary to ship the RCM8, use the original
shipping container if possible to ensure safe transportation.
Mounting Instructions
After the DIP switches and jumpers are set correctly (as
described in the section entitled Settings and Connections),
mount the RCM8 on a wall at the selected location. THIS
DEVICE IS FOR INDOOR USE ONLY!
Mounting Requirements:
Enclosure Type: NEMA 1
Hole Pattern: 15.44" x 7.00" (392.23mm x 177.80mm)
Fasteners: Use four 1/4" (6mm) bolts
Weight: 15 lbs. 8 ozs. (7.2kg)
Figure 2 describes the physical dimensions of the RCM8.
Physical Connections
The RCM8 can be installed and configured at the hardware level
to your specific application according to several configurations:
• A single RCM8 (with or without a PC or video display
terminal connected)
• Multiple RCM8 units (Master, Slaves, and Repeaters) in a
local configuration
• RCM8 with SiteScan central monitoring system
Liebert RCM8 • 5
• RCM8 with local, short-haul modems
• RCM8 with dial-up modems to remote locations and pagers
• RCM8 monitoring multiple remote locations from a central
location
Diagrams in Appendix B at the end of this manual describe
possible RCM8 configurations.

DIP Switch SW1 Descriptions
• Address (1 and 2)—Addressing allows up to four RCM8
units to be linked together. Overlapped addresses are
allowed only for dial-up operation without SiteScan.
• EIA-485 Master or Slave (3)—If ON, the Master unit polls
the EIA-485 Slaves and has dial-out capability for the
connected units. For Slave units at the ends of each EIA-485
string, set P4 jumper to IN. For all other units, set the P4
jumper to OUT. Modems do not directly attach to slave
units.
• EIA-485 Baud (4)—9600 baud works for most multiple-
unit applications. If communications are not working: check
cable distance; check for a noisy communications
environment; or try using 1200 baud.
• Latching Alarms (5)—When ON, alarms will not clear
until the Silence/Reset switch is pressed and held for two
seconds.
• Repeater (6)—A repeater RCM8 unit is connected at a
different location to echo alarms received by the primary
unit(s). When ON, the eight inputs of the repeater unit are
disabled and the display echoes incoming alarms. Master
repeaters display all alarms. Slave repeaters display alarms
only from RCM8 with a matching address.
