Compatible Polling Loop Devices (cont’d)
4208U Universal 8-Zone
Expander
• Uniquely identifies 8 EOLR supervised
zones (all zones use 10k resistors,
supplied).
• Can be used in zone assignment mode or
serial number mode.
• When used in the serial number mode,
each serial number in the selected group
can be assigned to any zone number.
• Loops A&B can be programmed for fast
(10msec) response.
• Can be optionally powered from an
external DC power supply to reduce
current draw from the polling loop.
• Tamper protected
4209U Universal Group
Zoning Module
• Uniquely identifies 4 supervised zones or 2
supervised zones in the “grouped” mode
(groups 2 supervised zones into one zone).
• Supports up to 16 2-wire smoke detectors
on each of its 4 loops, regardless of group
setting.
• Can be used in zone assignment mode or
serial number mode.
• When used in the serial number mode,
each serial number in the selected group
can be assigned to any zone number.
• Tamper protected.
4193SN Serialized 2-Zone
Expander
• Two-zone expander used to connect alarm
sensing devices to control panels.
• Can be configured as one supervised zone
(10K EOLR) and one unsupervised zone, or
two unsupervised zones (normally closed
devices only).
• Serial number ID programmed by control
panel.
4293SN Serialized 1-Zone
Expander
• Single-zone expander used to connect
alarm-sensing devices to control panels.
• Can be configured as one unsupervised
zone (normally closed devices only).
• Serial number ID programmed by control
panel.
