Description

The Siemens ZR-MC-R Strobe P/N: 500-636169 Red is a visible fire alarm notification appliance from the Siemens Z Series. It is a red wall-mounted strobe with FIRE marking, a clear lens, and field-selectable candela output.

The ZR-MC-R uses xenon strobe technology and operates from compatible 24V notification appliance circuits. Its separate snap-on mounting base allows circuit wiring to be completed and tested before the finished strobe is attached.

Product Functions

• Provides visible fire alarm notification
• Strobe-only notification appliance
• Designed for wall mounting
• Red housing
• FIRE marking
• Clear strobe lens
• Provides four selectable candela settings
• Supports synchronized visual notification
• Operates on compatible 24V notification circuits
• Uses xenon strobe technology
• Uses a separate snap-on mounting base
• Designed for conventional fire alarm NAC circuits

Multi-Candela Strobe

The ZR-MC-R provides four field-selectable visual output settings:

15 cd

30 cd

75 cd

110 cd

The selectable design allows one appliance to accommodate different visual notification requirements without changing the entire strobe.

Xenon Strobe Technology

The ZR-MC-R uses a xenon flash tube enclosed behind a clear Lexan lens.

The strobe produces approximately:

1 flash per second

throughout its specified operating voltage range.

The appliance is a visible-only notification device and does not contain an electronic horn or speaker.

Wall-Mount Configuration

The ZR-MC-R is specifically designed for wall mounting.

Its configuration is:

Model: ZR-MC-R

Part Number: 500-636169

Function: Strobe

Color: Red

Marking: FIRE

Lens: Clear

Mounting: Wall

Candela: 15 / 30 / 75 / 110 cd

The corresponding white wall model is ZR-MC-W, P/N 500-636170.

Synchronized Notification

The ZR-MC-R supports synchronized visual signaling with compatible Siemens fire alarm equipment.

Synchronization allows multiple strobes within the same field of view to flash together rather than independently.

Compatible Siemens control panels, synchronization modules, and NAC extenders can provide the required synchronization protocol.

Snap-On Base Design

The ZR-MC-R uses a separate Z Series mounting base.

The corresponding red base is:

ZB-R / ZBB-R — P/N 500-636193

The base allows field wiring to be installed and tested before the finished strobe appliance is attached.

Shorting contacts provide circuit continuity during initial wiring. Installing the appliance opens these contacts so normal notification circuit supervision can begin.

Product Status

The Siemens ZR-MC-R / 500-636169 is a discontinued Z Series notification appliance. Siemens’ November 2025 product-status documentation identified it as a discontinued red wall FIRE xenon strobe with clear lens and low multi-candela output.

For replacement applications, candela output, 24V circuit compatibility, synchronization protocol, mounting orientation, and existing base compatibility should be considered.
