The system suppofts up to 8 wireless transmitters
(5700 series), plus wireless keypads. These can
be assigned to any zone between 1 and 63.
To expand the system using wireless, one or two
4281- type RF Receivers can be used.
Any zone from 1-63 can be used as a 5700
series wireless zone. The total number of
transmitters supported by each type of 4281
receiver is shown in the “transmitters supported”
table at the left.
The 4281-type RF receiver will respond to status
and alarm signals from wireless transmitters
(345 MHz USA; 315 MHz Canada) within a
nominal range of 200 feet, and relays this
information to the control.
Two of the same type of receivers can be used to
provide either a greater area of coverage, or to
provide redundant protection.
Receivers must be mounted externally to the
control. See
UL note be/ow.
The 4281 receiver is connected to the console
data lines.
If the connection is broken between the receiver
and the control panel, a TROUBLE will be
displayed for zones 89 or 91 (if type 05 is
assigned). In addition, all zones associated with
the RF device will report a trouble condition.
If, within a programmed interval of time, the
receiver does not hear from any of its
transmitters, a TROUBLE will appear for zones
88 or 90 (if type 05 is assigned).
J Receivers respond only to transmitters set to the
same house ID (01-31). This prevents system
interference from transmitters in other nearby
systems.
I Use Sniffer Mode (described later) to make sure
you do not choose a House ID that is in use in a
nearby system.
B4281 house ID is programmed via field 1
●51
J To check for house IDs being used in nearby
systems, set receiver’s House ID to “00” (in field
1
●51, then enter your “installer Code”+ [#]+ [2].
The receiver will now “sniff” out any House IDs in
the area and display them. Keeping the receiver
in this mode for about 2 hours will give a good
indication of the house IDs being used. To exit
the Sniffer Mode, simply key your installer code +
OFF, then set your house ID to one not displayed
in the “Sniffer Mode”.
LJLNOTE: In UL installations, the 4281 must be mounted within 3 feet of the
