Edwards 870-B Back Box for 870 and 871 Series

Product Description

The EDWARDS 870-B is a back box designed to house and protect components in the 870 and 871 series alarm and signaling devices. It provides a secure, flush-mount enclosure that keeps internal wiring and electronics shielded from environmental exposure and physical contact. Licensed electricians and fire alarm technicians install this type of back box as part of a complete device assembly during new construction or retrofit projects. Weighing 1.28 pounds, it is a compact, purpose-built enclosure suited for both commercial and light industrial fire alarm or notification system installations.

This back box is used in applications where the 870 or 871 series device requires a dedicated wall-mount housing. Typical installations include commercial buildings, industrial facilities, and institutional spaces where fire alarm notification appliances must be securely mounted to wall surfaces. It is intended to be installed before the primary device is mounted, allowing wiring to be routed and secured within the enclosure prior to final device attachment.
