DESCRIPTION
GEM-RECV-XP8 receiver Is the hardwired interface to
Napco's Wireless-Ready,. XP-Serles and GEM-P800 Con-
trol Panels. The wireless system comprises an XP-400:
-
XP-600 or GEM-P800 panel, at least one GEM-RECV-XP8
receiver and one or more companion transmitters. The
transmitters may be wireless smoke detectors, space-
protection devices, window/door sensors, or other devices
that report zone status and supervision information to the
receiver without the use of wires.
THE GEM-RECV-XPB RECEIVER
The GEM-RECV-XPB wUI accommodate up to 8 wireless
transmitters,
4
GEM-SMK wireless smoke detectors, and
4
GEM-KEYF Key-Fob
transmitters.
The receiver is con-
nected to the keypad 3-wlre bus. The receiver monitors
each transmitter, updating transmltter status as reports are
received, and conveys this information to the control panel.
Also monitored
is
the elapsed time since the last report from
each transmitter. If no report Is received within a
programmed time, the panel wDI issue a Supervisory Failure
system trouble.
COMPATIBLE TRANSMITTERS
Any
of
the following Napea wireless transmitters may be
used with the GEM-RECV-XP8 receiver.
• GEM-TRANS2 Window/Door Sensor. This super-
vised, two-point transmitter provides an Internal mag-
netic reed switch and/or terminals for one or two
external normally-closed devices.
• GEM-TRANS4 Window/Door Sensor. As above, but
4
points.
• GEM-PIR. Dual-element passive
infrared
sensor.
-
• GEM-DT. Dual-technology PIA/microwave sensor.
• GEM-SMKSmoke
Detector.
Supervised smoke detec-
tor.
• GEM-KEYF Key Fob Transmitter. Keychaln/pendant
remote arming or emergency transmitter.
• GEM-GB. Glass-break sensor.

INSTALLATION
Designing the System
In planning the layout of the system, give careful con-
sideration to the location of the receiver. Regardless of
where the control panel Is mounted, the receiver should be
centrally located Within the premises, that Is, approximately
equally distant from all transmitters. Choose a location as
high above ground level
as
practical (attic Installations are
not
recommended), keeping In mind that metal objects may
adversely affect reception Draw a layout
of
the system,
Identifying all proposed transmitter locations
and
anticipated
receiver location Also Include notations Indicating construc-
tion materials In use. Although wood and wallboard con-
struction wUI have little effect upon signal strength at the
receiver, concrete or brick can reduce signal strength by
up to 35%, while steel-reinforced concrete or metal lath and
plaster can reduce transmitter strength as much as 90%.
In installations where distant transmitters pose reception
problems, two receivers (maximum)
may
be used. The
panel will respond to receiver with the stronger signal. Both
receivers are connected to the panel's 3-wlre bus, but they
must be addressed differently so that they can be Identified
by the control panel. This
Is
accomplished by the placement
of
jumper JP1 at the lower-left comer
of
the board. Refer to
