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. NOTE When the following symbols are displayed, they indicate: a. Earth grounding conductor b. Alternating Current Figure 1. Typical System Configuration Section 1: INTRODUCTION The Liebert RCM4 is a basic alarm panel. This device monitors four sets of non-powered, normally open (N.O.) contacts. In response to detection of an alarm, the RCM4 activates a LED; optionally, it also activates an audible alarm and a common alarm output. All interconnections are Class 2 circuits. The unit is configured for latching or non-latching operation, and the Form-C common alarm output can operate in supervised or unsupervised mode. The only user control is the Silence/Reset button. The RCM4 may monitor contact-closures from a Liebert unit, or any generic sensor or signalling device that provides N.O. contacts as output. Specifications Electrical Specifications: Voltage: 24 VAC/DC, +/-10% of nominal Power: 6 VA Phase: 1 Frequency: 50/60 Hz Environmental Conditions: Operating Temperature: 5°C to 40°C Operating Relative Humidity: 0% to 95% (non-condensing) Operating Altitude: up to 2000 meters Dimensions: 6.5”H x 6.5”W x 3.1”D 165mm x 165mm x 78mm 3.2 lbs 1.45 kg Agency Approvals: UL873 - Temperature-Indicating and Regulating Equipment Liebert RCM4 • 1 Section 2: INSTALLATION Mounting The RCM4 is designed for wall-mounting on a finished interior wall. Separate the display module from the base plate by removing (3) screws -- (2) on top, (1) on bottom of unit. Save screws for use later in re-assembly. Using appropriate tools, remove conduit knock-outs as necessary. Knock-outs are provided on the top and rear surfaces. Using the base plate as a template if necessary, locate and drill (2) mounting holes. Refer to Figure 2. Using #10 screws, affix base plate to interior wall. Ensure base plate is secure and level. Pull all necessary power and signal wires through knock-outs on base plate prior to connecting to display module. Refer to subsection on Electrical Connections. Ensure all interconnects are in place before re-attaching the display module to base plate. Call Liebert Environmental Support at 1-800-543-2778 if assistance is required for the installation or operation of the RCM4 remote contact monitor. Figure 2: Enclosure and Mounting Dimensions Liebert RCM4 • 3 Electrical Connections Wiring considerations for the RCM4 can be partitioned into (3) categories: alarm inputs; common alarm output; power. Refer to Figure 3. Note: Minimum 20AWG wiring recommended for all field connections. Alarm input #1 is wired to TB1-1 and TB1-2; alarm input #2 is wired to TB1-3 and TB1-4; alarm input #3 is wired to TB1-5 and TB1-6; alarm input #4 is wired to TB1-7 and TB1-8. Each input is connected to a normally-open (N.O.) contact; upon closure of this contact, the RCM4 signals an alarm condition. It is recommended that the RCM4 be placed no further than 300 feet (100 meters) from the signalling device. The RCM4 provides a Common Alarm Output, at TB3. This Form-C dry-contact is rated for Class 2 circuits 24VAC @ 3A. Note that the common alarm can be wired for supervised or unsupervised operation. Power for the RCM4 is supplied to TB2-1 and TB2-2. Maximum current draw is 0.25A at 24V AC/DC. It is strongly recommended that the RCM4 be powered independently by an external transformer.

Position 1 6 OFF Alarm #1 Unlatched Alarm #2 Unlatched Alarm #3 Unlatched Alarm #4 Unlatched Audible Alarm Disabled See Note 1 7 See Note 1 8 Normal Mode of Operation 2 3 4 5 ON Alarm #1 Latched Alarm #2 Latched Alarm #3 Latched Alarm #4 Latched Audible Alarm Enabled Unsupervised Common Alarm Output Supervised Common Alarm Output Test Mode See Note 2 Table 1: DIP Switch Settings Notes: 1. Position #6 and #7 cannot be ON at the same time. If 6 and 7 are both OFF, common alarm relay is disabled. Supervised common alarm relay is energized on power up; unsupervised relay is energized on detection of alarm. 2. Position #5 must be ON to test audible alarm. LEDs and Audible Alarm Tested (only the LEDs that are in the latched mode). Liebert RCM4 • 5 Section 4: OPERATION There are two basic modes of operation for the RCM4 – latched or unlatched. The following subsections detail the respective operation sequences. Latched Operation When an external alarm contact closes, the RCM4 latches the alarm indicator (LED), latches the audible alarm, and activates the common alarm output. The audible alarm will continue to sound until the SILENCE/RESET button is pressed, regardless whether the alarm condition has cleared itself or not. The common alarm output always tracks the status of the inputs. However, the behavior of the alarm LED is more complex; the following two examples illustrate the subtle differences. Example 1: Latched/Silence before alarm clears. When the SILENCE/RESET switch is pressed while an alarm is active, only the audible alarm will be silenced. The alarm indicator will remain on until the input alarm condition is cleared. Event Alarm Input 1 2 No Alarms Contact Closes Alarm Active Alarm Stays Active; SILENCE/RESET pressed Alarm Clears 3 4 NORMAL Status LED Green Unlit ALARM Status LED Unlit Red Common Alarm Not Active Active Audible Alarm Off On Unlit Red Active Off Green Unlit Not Active Off Example 2: Latched/Silence after alarm clears. When the alarm condition clears itself before the SILENCE/RESET switch is pressed, the alarm LED and audible alarm will continue to be active until user acknowledgement. The common alarm output tracks the alarm input; thus it will be de-activated when the alarm condition clears. Event Alarm Input 1 2 No Alarms Contact Closes Alarm Active Alarm Clears 3 4 SILENCE/RESET pressed NORMAL Status LED Green Unlit ALARM Status LED Unlit Red Common Alarm Not Active Active Audible Alarm Off On Green Red Not Active On Green Unlit Not Active Off Liebert RCM4 • 7 Unlatched Operation The common alarm output, alarm indicators, and audible alarm track the input alarm condition. If an alarm is present and the Silence/Reset switch is pressed, then only the audible alarm is silenced. If a new alarm is detected, the audible alarm is retriggered for the new occurrence. Example 3: Unlatched/Silence before alarm clears. When the SILENCE/RESET switch is pressed while an alarm is active, only the audible alarm will be silenced. The alarm indicator will remain on until the input alarm condition is cleared. There is no functional difference between latched and unlatched modes when alarms are acknowledged while they are active. Event Alarm Input 1 2 No Alarms Contact Closes Alarm Active Alarm Stays Active; SILENCE/RESET pressed Alarm Clears 3 4 NORMAL Status LED Green Unlit ALARM Status LED Unlit Red Common Alarm Not Active Active Audible Alarm Off On Unlit Red Active Off Green Unlit Not Active Off Example 4: Unlatched/Alarm clears prior to Silence. When the alarm condition clears itself before the SILENCE/RESET switch is pressed in the unlatched mode, the visible and audible alarms will automatically reset without user intervention. This is the main difference between the latched and unlatched modes of operation.
