MPC-6000 / MPC-7000 / RND-2 INSTALLATION, OPERATION AND MAINTENANCE MANUAL

GENERAL DESIGN FEATURES

Environmental

The MPC-6000/MPC-7000/RND-2 panels and subassemblies are suitable for use in a dry,
interior or protected location.

Power Limiting

The AC power, battery wiring and open collector circuits (when MPC-REL is installed) are not
power limited. All other circuits leaving the control unit are power limited, provided the proper
installation rules are maintained.

Ground Fault Detection

The control unit provides system ground fault detection and is annunciated as a trouble
condition on the system. In addition, each addressable loop circuit has its own ground
detection circuitry and indicator.
System (+) Ground Fault Threshold <20kΩ
System (-) Ground Fault Threshold <20kΩ

NAC Operation

The notification appliance circuits are commanded and controlled by a microprocessor.
 Output Sounding Patterns - The notification appliance circuits are operable in different
sounding patterns. Any circuit is selectable to any of five software-generated patterns or
continuous sounding.
 Audible Silence Inhibit - In addition to designation of water flow zones, the entire control
unit may be programmed to inhibit audible silence for 0, 1, 3, or 6 minutes from the last
alarm. System reset may also be inhibited.
All of the NACs are power limited and support synchronization of listed devices. If a NEM-1 is
installed in an MPC-7000 panel, its NACs are synchronized in sets of 4 as follows:
• NAC1, NAC2, NAC3 and NAC4 are synchronized with each other.
• NAC5, NAC6, NAC7 and NAC8 are synchronized with each other.
• NAC9, NAC10, NAC11 and NAC12 are synchronized with each other.
A maximum of one NEM-1 NAC Expander board can be installed per MPC-7000 panel.

Transient Protection

Transient protection devices are provided to meet UL864 requirements.

Security Features

Processor control and addressing allow inclusion of several functions to assure security and
proper programming of the system.
Multi-level password protection of programming functions prevents unauthorized configuration
changes.
Device type supervision: If the type reported by an addressable detector or module does not
agree with the configuration, the system reports a trouble condition.
