NMM-100P Mini Monitor Module: Compact Monitoring Excellence

The NMM-100P Mini Monitor Module is a versatile device designed for intelligent two-wire systems, where individual module addressing is achieved through rotary switches. It excels in providing a two-wire initiating device circuit for normally-open-contact fire alarm and security devices. Here are its notable features and specifications:

Key Features:

• Built-in Type Identification: This module is automatically recognized as a monitor module by the panel, simplifying installation.
• Direct Power Supply: Powered directly by the two-wire SLC loop, eliminating the need for additional power sources.
• High Noise Immunity: Offers robust resistance to electromagnetic interference (EMF) and radio-frequency interference (RFI).
• Convenient Wiring: Tinned, stripped leads for easy and efficient wiring.
• Direct-Entry Addressing: Users can directly dial an address within the range of 01 – 99 on FireWarden-100-2 and 01 – 50 on FireWarden-50.

Applications:

• Ideal for monitoring single devices or zones containing four-wire smoke detectors, manual fire alarm pull stations, waterflow devices, and other normally-open dry-contact devices.
• Suitable for monitoring normally-open supervisory devices, providing special supervisory indication at the control panel.
• Monitored circuit/device wired in NFPA Style B (Class B) Initiating Device Circuit configuration.
• Equipped with a 47K Ohm End-of-Line Resistor (included) to terminate the circuit.

Operation:

• Each NMM-100P occupies an available module address on an SLC loop.
• It responds to regular polls from the control panel, reporting its type and the status (open/normal/short) of its Initiating Device Circuit (IDC).

Specifications:

• Nominal Operating Voltage: 15 to 32 VDC.
• Average Operating Current: 350 µA, 1 communication every 5 seconds, 47k EOL; 600 µA Max. (Communicating, IDC Shorted).
• Maximum IDC Wiring Resistance: 1500 Ohms.
• Maximum IDC Voltage: 11 Volts.
• Maximum IDC Current: 450 µA.
• EOL Resistance: 47K Ohms.
• Temperature Range: 32°F to 120°F (0°C to 49°C).
• Humidity Range: 10% to 93% non-condensing.
• Dimensions: Compact dimensions of 1.3" (3.302 cm) in height x 2.75" (6.985 cm) in width x 0.65" (1.651 cm) in depth.
• Wire Length: Minimum wire length of 6" (15.24 cm).

The NMM-100P Mini Monitor Module packs monitoring excellence into a compact form, making it ideal for discreet mounting in single-gang boxes behind monitored devices. Its reliability, ease of use, and versatility are well-suited for a range of applications.
