Models CPD-705X
are dual chamber Ionization Smoke Detectors that sense visible and invisible products of combustion.
Models PSD-715X
are optical Photoelectric Smoke Detectors that respond to a broad spectrum of both flaming and smoldering fire conditions.
Models THD-705X
are thermistor-based electronic Heat Detectors with a 135°F (57°C) Fixed Temperature set point. The Model THD-7052 has a
Rate-Of-Rise of temperature detection feature rated at 15°F (8.3°C) per minute.
All detectors are designed for 2-Wire and 4-Wire installation using the appropriate Detector bases. The Smoke and Heat Detectors are UL Listed for
Open Area Protection applications per UL 268 and UL 521 respectively. Detectors may also be installed in systems intended for Releasing Device
Service through use of a compatible Fire Alarm Control Panel.
