The Siemens ZR-MC-R Strobe P/N 500-636169 is a red, wall-mounted multi-candela visual notification appliance from the Siemens Z Series. It is designed to provide visible fire alarm notification using a field-selectable strobe with 15, 30, 75, or 110 candela settings. Siemens identifies part number 500-636169 specifically as the ZR-MC-R Z Series Multi-Candela Wall Strobe, Red.
The ZR-MC-R operates from 16–33 VDC or VFWR notification appliance circuits and flashes at approximately one flash per second across its listed operating voltage range. It uses the Siemens Z Series snap-on mounting system, allowing the base to be installed and wired before the strobe appliance itself is attached.
The ZR-MC-R provides four selectable visual intensities:
The selected candela determines the intensity of the visual flash and should be chosen according to the approved fire alarm design, mounting location, room size, viewing distance, applicable codes, and required visual coverage.
Because higher candela settings generally require more notification circuit current, the selected setting must also be considered when calculating NAC loading and voltage drop.
The ZR-MC-R uses a xenon flashtube enclosed behind a durable lens assembly to provide visual emergency notification.
Siemens specifies:
Flash Rate: 1 flash per second
Operating Voltage: 16–33 VDC / VFWR
Visual Output: 15 / 30 / 75 / 110 cd
The strobe is intended for connection to a compatible supervised fire alarm Notification Appliance Circuit.
The ZR-MC-R is specifically a wall-mount strobe.
Siemens distinguishes the ZR Series configurations as follows:
This model should therefore be used in wall applications rather than substituted for the corresponding ceiling version.
A key feature of the Siemens Z Series is its snap-on mounting base.
The separate base can be installed and fully wired before the notification appliance is attached. This allows electricians and fire alarm technicians to test circuit continuity during construction while protecting the actual strobe from dust, paint, and physical damage.
After construction is complete, the ZR-MC-R snaps directly onto the prewired base.
The compatible red Z Series mounting base is:
ZB-R — P/N 500-636193
Siemens describes the ZB-R accessory package as including:
The same basic Z Series mounting platform is used across compatible horns, strobes, and horn/strobes, allowing more consistent installation and easier appliance replacement.
The ZR-MC-R supports Siemens strobe synchronization when used with compatible control equipment.
Documented compatible synchronization sources include Siemens equipment such as:
Synchronization allows multiple compatible visual appliances to flash together where required by the fire alarm design.
The ZR-MC-R uses polarized inputs for connection to compatible fire alarm Notification Appliance Circuits.
This supports normal reverse-polarity supervision methods used by fire alarm control equipment.
Correct polarity must be maintained during installation for proper operation and circuit supervision.
Part Number: 500-636169
Model: ZR-MC-R
Nominal System Voltage: 24 VDC
Operating Voltage Range: 16–33 VDC / VFWR
Candela Settings: 15 / 30 / 75 / 110 cd
Flash Rate: 1 flash per second
Circuit Type: Polarized Notification Appliance Circuit
Synchronization: Siemens compatible sync protocol
Strobe Technology: Xenon
The exact current draw varies according to the selected candela setting and should be taken from the applicable Siemens installation documentation when calculating NAC loading.
Housing Color: Red
Lens: Clear
Marking: FIRE
Mounting: Wall
Approximate Dimensions: 4.85 × 4.85 × 1.56 in
Approximate Weight: 0.4 lb
The low-profile square design allows the appliance to maintain a consistent appearance with other Siemens Z Series horns, strobes, and horn/strobes.
Operating Temperature: 32°F to 120°F / 0°C to 49°C
Maximum Relative Humidity: Approximately 93% RH
Environment: Indoor
The ZR-MC-R is not the weatherproof version of the Siemens strobe family. Outdoor or wet-location installations require an appropriately listed weatherproof appliance.
Typical ZR-MC-R installation includes:
The snap-on base design allows circuit installation and testing to be completed before the notification appliance itself is exposed to construction conditions.
Testing should confirm:
The appliance should also be inspected for physical damage, contamination, paint, loose mounting, or other conditions that could reduce visual notification performance.
