Installation
The FAPT-851 plug-in detector uses a separate base to
simplify installation, service, and maintenance. A special tool
allows maintenance personnel to plug-in and remove detec-
tors without using a ladder. Mount base on a box at least
1.5 in. (38 mm) deep. Suitable mounting base boxes include:
• 3.5 in. (89 mm) or 4.0 in. (102 mm) octagonal box
• Single-gang box (except relay or isolator base)
• With B224RB or B224BI base, use a 3.5 in. (89 mm)
octagonal box, or a 4.0 in. (102 mm) 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 F-9587 (ISO-X) for device limitations between isolator
modules and isolator bases.
Application Note:
The FAPT-851 detector has the unique
ability to adjust sensitivity according to the environment,
based on heat and smoke levels. Avoid installing these
detectors in locations that are susceptible to rapid and high
temperature changes. An example of an incorrect application
would be near or in line with the output of a self-contained
heater.
