Simplex 4098-9764 — TrueAlarm multi-sensor combining photoelectric smoke sensing with an integral thermal sensor in one addressable head.
It reports analog smoke and heat data over IDNet two-wire communications while occupying a single address, and the control unit compares each present value against a tracked average. Simplex calls the combined evaluation TrueSense: fixed temperature, rate-of-rise, photoelectric and correlation detection run together.
- For 4007ES, 4010ES, 4100ES and 4100U control units; 4100U needs software revision 11 or higher
- Smoke sensitivity 0.2 to 3.1 percent per foot obscuration, selectable at the panel
- Thermal alarm fixed at 135°F (57.2°C); rate-of-rise selectable at 15°F or 20°F per minute
- Rated air velocity 0 to 4000 ft/min (0 to 1220 m/min)
- UL certified range 32°F to 100°F (0°C to 38°C); UL 268 7th Edition
The base is ordered separately and sets the feature set: 4098-9792 standard, 4098-9789 remote LED, 4098-9793 isolator, 4098-9794 sounder. Do not confuse it with the 4098-9754 multi-sensor or the photoelectric-only 4098-9714.

FAQ
Which panels support the 4098-9764?
It is for use with Simplex 4007ES, 4010ES, 4100ES and 4100U control units. 4100U panels require software revision 11 or higher with multi-point compatible IDNet transmission modules.
Does it use one address or two?
One. Special point types let the multi-sensor send both smoke and heat analog data on a single IDNet address.
Is a base included?
No. It is compatible with standard TrueAlarm bases, including relay, sounder and isolator bases, which are ordered separately.
How can alarms be determined?
By smoke detection from 0.2% to 3.1% per foot obscuration, by heat detection as fixed temperature or fixed with rate-of-rise, or by TrueSense analysis of smoke and heat combined.
