The Simplex 4098-5602 Conventional Optical and Heat Detector Head provides combination fire detection for compatible Simplex conventional fire alarm systems. It integrates advanced optical sensing technology with a 135°F fixed-temperature heat sensor. In addition, its automatic sensitivity compensation and magnetic testing features support professional maintenance and inspection.
Designed for compatible two-wire and four-wire detector bases, this combination detector offers a practical solution for commercial and institutional fire alarm installations.
The detector uses two sensing methods to monitor potentially dangerous fire conditions.
First, its optical sensing chamber evaluates airborne particles associated with developing fires. Meanwhile, its integrated thermal element monitors surrounding temperature.
Therefore, the detector combines particle-based sensing with fixed-temperature heat detection in one compact housing.
An onboard microprocessor evaluates sensing information and determines when the detector should activate.
The integrated thermal element has a fixed-temperature rating of 135°F (57.2°C).
This sensor provides an additional method of detecting fire conditions when the surrounding temperature reaches its rated threshold.
Unlike a rate-of-rise heat detector, this model does not use a separate rapid-temperature-increase alarm threshold.
Consequently, installers should select the detector according to the approved fire alarm design and required detection characteristics.
The detector includes onboard software that compensates for gradual contamination in the optical sensing chamber.
Over time, dust and dirt can affect sensing performance. However, the compensation feature helps maintain sensitivity within the detector’s designed operating limits.
Moreover, the device monitors contamination levels and provides diagnostic information when maintenance becomes necessary.
As a result, technicians can identify conditions that require attention during routine inspections.
The detector supports magnetic functional testing for inspection and troubleshooting.
A qualified technician can use the appropriate test magnet to initiate the test sequence.
The detector’s red LED provides visual feedback during testing. If the device identifies an abnormal condition, the LED can display diagnostic pulses before entering the test alarm state.
Therefore, technicians can evaluate detector status without removing the sensing head.
The detector features a compact, low-profile housing designed for approved indoor installations.
Its plug-in construction allows the head to attach to a compatible Simplex mounting base.
Consequently, technicians can remove or replace the detector head without disconnecting the base wiring.
The mounting base is a separate accessory unless the product package specifically includes one.
The Simplex 4098-5602 operates with compatible conventional initiating device circuits.
For two-wire applications, the documented operating voltage ranges from 10.5 to 33 VDC.
Meanwhile, compatible four-wire configurations use a rated voltage range of 15 to 32 VDC.
The detector itself does not provide an individual digital device address.
Therefore, installers must verify the control panel, initiating circuit, and mounting base before installation.
The manufacturer identifies several compatible mounting bases.
These include the 4098-5261 four-inch two-wire base and the 4098-5207 five-inch two-wire base.
Additional options include the 4098-5680 and 4098-5682 relay bases.
However, technicians must confirm the exact base and panel compatibility before selecting replacement components.
The detector operates in ambient temperatures from 32°F to 100.4°F (0°C to 38°C).
It supports relative humidity from 10% to 95%, non-condensing.
In addition, its optical sensing section supports an air velocity range from 0 to 2,000 feet per minute.
The housing uses flame-retardant ABS or PC-ABS plastic.
This combination detector supports compatible commercial and institutional fire alarm installations.
Typical applications include office buildings, schools, hotels, healthcare facilities, retail properties, warehouses, and other approved indoor environments.
Its combination sensing design is useful where the approved fire alarm system requires both optical and thermal detection in a single device.
Before installation, verify the fire alarm control panel, mounting base, electrical requirements, and environmental conditions.
Also, inspect the detector for damage, contamination, and correct identification markings.
Qualified fire alarm professionals should install and test the device according to Simplex instructions and applicable fire alarm codes.
Overall, this Simplex combination detector provides optical and thermal fire detection for compatible conventional systems. Its integrated 135°F heat sensor, automatic sensitivity compensation, and magnetic testing capability make it suitable for professional installation, maintenance, and replacement projects.
