The Hochiki NS4-224 detector base is a 4-inch 2-wire conventional mounting base. It is electronics-free and uses an integral current-limiting resistor.
First, the NS4-224 provides a fixed platform for a Hochiki conventional smoke or heat detector head. Then it ties the head into a 2-wire initiating circuit. As a result, panels can supervise the device through a single pair of conductors.
Hochiki NS4-224 Detector Base Specifications
- Alarm current: 43 mA at 24 V (70 mA at 33 V max)
- Compatibility ID: HB-5
- Wiring: 2-wire conventional
- Base diameter: 4 inches
- Box mounting: 3-inch octagonal box only
- Color: bone or white (W suffix)
- Listings: UL Listed, CSFM 7300-0410-0132
Compatible Detector Heads
Also, the NS4-224 accepts Hochiki photoelectric and heat heads. Specifically, it works with SOC-24V, SOC-24VN, SLR-24V, SLR-24H, SLV-24, SLV-24N, and SLV-24V smoke detectors. In addition, it supports SLR-835 and SLR-835H photoelectric heads. Furthermore, the DCD-135/190 fixed-temperature/rate-of-rise heat detector also mounts here.
Installation Notes
However, the NS4 footprint mounts only on a 3-inch octagonal box. Therefore, do not substitute a 4-inch box; the NS6 series is the 4-inch-box version. Also, any LED annunciation device must be current-limited to 20 mA at 24 VDC.
