Fireboy-Xintex OMHD-04-DB-R, Mariners Warehouse SKU 98648, supplies a fixed heat detector and base for a documented compatible fire-alarm system. It uses a thermistor that responds to the air temperature at the sensing location. Choose it from the engineered panel/zone arrangement and intended environment, rather than selecting a detector by supply voltage alone.

The store identifies a 163°F fixed-heat version, and Fireboy’s conventional-device literature distinguishes the OMHD-04 BS static class from rate-of-rise variants. Select the exact marked detector for the system design rather than borrowing a rate-of-rise response from a general heat-detector paragraph. White flame-retardant polycarbonate construction, nickel-plated stainless terminals and a remote-test feature are listed.

Have a qualified fire-alarm installer verify the exact detector, base and control-panel compatibility, including the approved zone wiring and reset arrangement. The source lists an 8.5–33V DC two-wire, polarity-sensitive supply; matching voltage alone does not establish panel compatibility. Locate, connect, commission and maintain the detector under the full system instructions. A detector and base do not supply the complete alarm-notification system or guarantee coverage of every space.

Compatibility & Setup Guides

Match the Device to Its Communication or Monitoring Task

Check OMHD-04-DB-R by its actual communication, heading, alarm-output, mounting or satellite-TV role. Confirm supported systems, power, connections, contents and setup requirements before purchasing.

Fixed-Heat Detector or Optical Smoke Detector?

Fireboy-Xintex OMHD-04-DB-R is the listed fixed-heat detector with base. OMSD-01-DB-R is the separately listed optical smoke detector with base. The models respond to different physical conditions and must be selected for the intended location and compatible panel design.

Choose the detector type specified for the zone rather than treating the two bases or voltage ranges as proof of interchangeability. Neither detector package supplies a complete fire-alarm panel and notification system, and one sensing method does not establish every function of the other. Review the Fireboy-Xintex Optical Smoke Detector with Base MPN - OMSD-01-DB-R as a separately sold option.

Frequently Asked Questions

What does SKU 98648 include?
One Fireboy-Xintex OMHD-04-DB-R fixed heat detector with its listed base. Compatible fire-alarm panel, notification/sounder equipment, zone wiring and installation supplies are separate. This is not a standalone battery alarm.

Is this a standalone battery alarm?
No. It is a component for an approved compatible fire-alarm system, with separate panel and notification equipment.
What sensing method does this model use?
Fixed-heat sensing with a thermistor. Confirm the exact marked threshold/classification; do not substitute a rate-of-rise description.
Does the supply range prove panel compatibility?
No. The source lists 8.5–33V DC with a two-wire polarity-sensitive connection, but exact detector/base/zone compatibility must also be verified.
Will it prevent all false alarms or detect every fire?
No such guarantee is made. Location, environment, maintenance and the complete system design matter.
Who should confirm installation and testing?
A qualified fire-alarm installer should verify the approved system combination, location, wiring, commissioning and ongoing test procedure.
How can I confirm the right selection?
Contact Mariners Warehouse with SKU 98648, MPN OMHD-04-DB-R, your fire-alarm panel model, detector/base version, zone circuit, intended location and required sensing classification.
