Smoke and Heat Detector DSC 88031148 - combined smoke and temperature sensing

The DSC 88031148 combined smoke and heat detector integrates optical smoke sensing with temperature monitoring in a single low-profile enclosure. Designed for use with compatible DSC and third-party alarm control panels, the unit detects airborne combustion particles and rapid temperature rise to provide reliable fire detection for residential and commercial indoor environments. The detector is intended for permanent ceiling or wall mounting and for connection to supervised detection zones within conventional or addressable systems where supported.

Advantages

This combined detector reduces the need for separate devices by offering both photoelectric smoke detection and thermal sensing in one unit, simplifying installation and zone planning. The integrated design improves response to slow-smoldering fires and fast-developing heat events while maintaining a compact footprint. Its compatibility with standard alarm panels allows centralized monitoring, event reporting, and power supervision to meet building safety requirements.

Suitable for

• Residential living areas, hallways and bedrooms
• Small offices, meeting rooms and retail spaces
• Common areas in multi-unit dwellings and corridors
• Utility rooms and service areas where both smoke and rapid temperature rise are possible

Key specifications

• Detection principles: optical (photoelectric) smoke sensing and fixed/thermal rate-of-rise temperature detection
• Mounting: ceiling or wall mount compatible with standard electrical boxes and detector bases
• Power and connection: designed for integration with compatible alarm control panels; supports supervised wiring
• Enclosure: low-profile housing suitable for indoor use; materials compliant with standard fire detector construction
• Operating environment: indoor ambient temperatures and humidity ranges typical for residential and commercial buildings

How to use

Install the detector on a ceiling or high on a wall in accordance with the alarm system manufacturer’s installation guidelines and local fire safety codes. Connect wiring to the designated zone or address module on the control panel, ensuring correct supervision and power supply. Place detectors away from ventilation outlets, cooking appliances and other sources of false alarms; follow the panel’s wiring diagram and perform a functional test after installation to confirm communication and alarm signaling.

Usage recommendations

Test detectors regularly using the control panel’s walk test or the detector’s test function where available. Clean the detector housing periodically using a soft brush or low-pressure vacuum to remove dust buildup. Replace detectors or sensors according to the alarm system manufacturer’s service interval recommendations or after confirmed contamination or damage.
