munication enabled); 360 µA @ 24 VDC (one communication

tive; 0.3 A @ 110 VDC inductive; 1.0 A @ 30 VDC inductive.

6.2" (15.748 cm) x 1.2"
(3.048 cm).
Maximum:
25 devices between isolator bases.
INSTALLATION
FSP-851 plug-in detectors use a separate base to simplify in-
stallation, service, and maintenance. A special tool allows main-
tenance personnel to plug in and remove detectors without us-
ing a ladder.
Mount base on an electrical backbox which is at least 1.5" (3.81
cm) deep. Suitable mounting base boxes include:
• 4.0" (10.16 cm) square box.
• 3.5" (8.89 cm) or 4.0" (10.16 cm) octagonal box.
• Single-gang box
(except relay or isolator base)
.
•
With B501BH or B501BHT base,
use a 4.0" (10.16 cm)
square box.
•
With B224RB or B224BI base,
use a 3.5" (8.89 cm) octago-
nal box, or a 4.0" (10.16 cm) octagonal or square box.
NOTES: 1) Because of the inherent supervision provided by the
SLC loop, end-of-line resistors are not required. Wiring “T-taps”
or branches are permitted for Style 4 (Class “B”) wiring. 2) When
using relay or sounder bases, consult data sheet DN-2243
(ISO-X) for device limitations between isolator modules and isola-
tor bases.
