Remote Monitoring, Autochangeover and Leak Detection Equipment

The Liebert RCM4
contact common alarm relay output (rated at 24 VAC, 3 Amp) is provided. Four red LEDs illuminate
on the respective alarm and the alarm buzzer is silenced by a front panel switch. The RCM4 requires
a 24VAC or 24VDC power source. Power supply is not included.
The Liebert AC4
control for up to four Liebert Mini-Mate2 units within a room. The Liebert AC4 will enable redundant
units in an alarm condition, balance usage and test standby units at programmed intervals. Two
common alarm relay outputs are available. A built-in LCD and RS-232 port for direct PC/terminal
connection provides two options for configuration and monitoring of the product. The Liebert AC4
requires 24VAC input power.
The Liebert AC8
enables redundant devices during an alarm condition, balances usage of devices and tests standby
devices at programmable intervals. Supports four zones and can use the 4-20mA temperature sensor
(TW420) for temperature staging in each zone. Two programmable output control relays are available
for auxiliary control such as humidity lockout. Emergency power operation input provided for device
control during an emergency. Two common alarm relay outputs are available. A built-in LCD and
RS-232 port for direct PC/terminal connection provides two options for configuration and monitoring
of the product.
The Liebert ENV-DO
major alarm conditions of Environmental units. The Liebert ENV-DO-ENCL1 packages one
Environmental DO interface card in its own steel enclosure and the ENV-DO-ENCL2 packages two
Environmental DO interface cards in one enclosure for installation external to the Liebert
Mini-Mate2. The self-contained kit includes an external 120VAC-to-24VAC power transformer.
Wiring harnesses are not provided. Power and communication wiring is field-provided.
The Liebert Liqui-tect
liquid using a pair of corrosion-resistant, gold-plated probes mounted in a painted, height-adjustable
enclosure. Dual Form-C, dry contact common alarm relays (rated at 24VAC, 3A) signal a leak
detected as well as loss of power and cable fault. The Liebert Liqui-tect 410 requires an external
24VAC or 24VDC power source.
Liebert LT460 Zone Leak Detection Kits include one LT460 sensor, a specified length of
LT500-xxY cable (maximum length is 100 ft [30.5m]) and a corresponding number of hold-down clips.
The Liebert LT460 requires an external 24VAC, 0.12A power source, such as EXT-XFMR or XFMR24.
Liebert SiteScan
manage the equipment critical to your business.
Liebert SiteScan enables communication from Liebert environmental and power units, as well as
many other pieces of analog or digital equipment, to a front-end software package that provides
real-time status and alarms so you can react quickly to changing situations.
Liebert SiteScan is designed with flexibility for both small systems and large, complex systems such
as those in computer rooms, telecommunications facilities or industrial process control rooms.
Contact your local Emerson representative for assistance with a Liebert SiteScan system.
The NIC-ENCL1 and NIC-ENCL2 package one or two Liebert IntelliSlot
Adapters, respectively, in one steel enclosure for installation external to the Liebert Mini-Mate2. The
Liebert IntelliSlot Web/485 Card with Adapter provides communication with the Liebert
Mini-Mate2 ™ via SNMP, HTTP, RTU Modbus 485 and BACnet IP. The self-contained kit includes an
external 120VAC-to-24VAC transformer as a power source. Wiring harnesses are not provided. Power
and communication wiring are field-provided.
