Description
Honeywell 4208SN 8-Zone Expansion Module for Polling Loop Systems
The Honeywell 4208SN is an 8-zone expansion module designed specifically for hardwired polling loop systems, adding eight additional hardwired zones to commercial alarm panels such as the VISTA-128BPT and VISTA-250BPT. This module supports serial number programming only and enables polling loop systems to extend their wiring distance up to 12,000 feet using just two connecting wires. The 4208SN is essential for large commercial installations requiring extensive hardwired sensor coverage, offering flexible wiring options and simplified installation compared to non-polling loop expanders that require four wires for connection.
Key Features:
- Adds 8 hardwired zones to polling loop systems; enables significant expansion of commercial alarm system capacity
- Extended wiring distance up to 12,000 feet; provides flexible installation options for large facilities with two-wire connection
