Universal Class A & Class B expander module
Addressable Universal Expander Module

The ADEMCO 4208SNF Remote Point Module (RPM) is a UL listed 8 zone expander that provides (6) class B and (2) class A expansions zones to any VISTA Fire/Burg control panel that supports serial V-Plex® polling loop devices.

  • Can be used on controls that support up to 250 zones
  • Provides up to six Class B supervised zones using external 10k EOL resistors and two Class A supervised zones using built-in 10k EOL resistors
  • Powered from addressable loop or optionally powered from an external DC power supply to reduce current draw from the addressable loop
  • Each zone is identified by a unique serial number, which is assigned via on-board DIP switches
  • Detects faults an all zones with 400msec of occurrence. Two Class B zones can be optionally set for fast (10msec) response via on-board DIP switches
  • Provides cover tamper protection, which may be enabled or disabled via on-board DIP switches
Class B to Class A Zone Converter Features
  • Allows up to two Class B control panel zones to be converted into Class A zones
  • Control panel’s response time to faults on the module’s Class A zones is equal to the response time of the control panel’s converted Class B zones plus one msec
  • Must be powered from an external 12vdc power supply such as the 12v auxiliary power output on the control panel
