Honeywell Ademco 4208SNF Expansion Module

• 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
• Allows up to two Class B control panel zones to be converted into Class A zones
• Control panels response time to faults on the modules Class A zones is equal to the response time of the control panels 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

• Dimensions: 6-7/16" x 4-1/4" x 1-1/4" (163 mm x 108 mm x 32 mm)
• Addressable V-Plex loop Voltage: 11v nominal; 8.7 - 14VDC range Current 33.6mA when polling loop provides power to
• module; 0.6mA when 12VDC input provides power to module
• 12VDC Input Voltage: 12V nominal: 9.4 - 14 VDC range Current: 33mA when this input provides power to module (optional)
• Used as a Class A Converter 12VDC Input Voltage: 12VDC nominal, 9.4 - 14VDC range, Current: 22mA
• Loop Response: Slow: 400msec (all loops) Fast: 10msec (options for loops A and B)
• Loop Current: 0.52mA (normal), 1.3mA_ (shorted)
• Sensor Loop Max Resistance: Loops A - F (Class 8); Up to 300 ohms of wire resistance + 10k EOLR; Loops G, H (Class A); Up to 150 ohms of wire resistance on each side
