XP95-DM
Description
The Gamewell-FCI Analog Addressable Discovery Multi-
Sensor detector (XP95-DM) includes both photoelectric
and thermal sensing elements integrated into a single
device. The XP95-DM digitally transmits its address to the
Fire Alarm Control Panel (FACP) plus the analog value for
analysis from both the photoelectric chamber and the ther-
mal sensor. The signals from the two sensors are com-
bined and processed using sophisticated algorithms
designed to prevent false alarms. The detector is automati-
cally programmed for pure heat detection, pure smoke
detection, or a combination of both dependent on ambient
conditions.
The XP95-DM Discovery multi-sensor detector operates
with all the Gamewell-FCI 600 Series analog addressable
FACPs. All of the detectors in the XP95 family have identi-
cal external dimensions and fit all base options. Polling and
external alarm status is indicated by dual LEDs located on
both sides of the detector housing. The thermal element of
the XP95-DM is designed for the free movement of air
around the exposed thermistor. The photoelectric detection
element uses a patented smoke chamber and infrared
smoke sensing design for maximum sensitivity and
selectivity.

Operation
The XP95-DM Multi-Sensor has both a photoelectric
detection chamber and a thermal sensing element. The
infrared LED in the photoelectric detection chamber emits
a burst of collimated light once per second or in response
to direct interrogation by the FACP.
In clean air, the photo diode receives no light from the
emitter. When the smoke enters the chamber, it scatters
light from the emitter onto the photo diode proportional to
the smoke's characteristics and density. As the smoke con-
tent in the chamber increases, the signal from the photo
diode increases.

Operation (Continued)
The XP95-DM monitors temperature using a single ther-
mistor which provides a voltage output proportional to the
external air temperature.
The thermistor is calibrated to the normal analog value at a
temperature of 25°C (77°F). Values from each sensing ele-
ment are processed by on-board electronics according to
detector programming. The XP95-DM Discovery multi-sen-
sor detector is automatically programmed for pure heat
detection, pure smoke detection, or a combination of both.

For air temperatures in the range of 59° F to 131° F
(15° C to 55° C) the analog value for a detector in Mode 1
will correspond approximately to the air temperature.
Programming
Assigning an XP95-DM detector to a verification zone
allows local operation when smoke is detected by the
optical element located in the head, and general alarm
operation when heat is present. When smoke is sensed,
the local sounder, relay, or LED located in the detector
base (or group of bases) will be activated, and a pre-alarm
signal will be sent back to the panel. The Aux (4th) relay on
the common control card will transfer. If heat is also
present, the panel will go into a full General Alarm condi-
tion. If there is only smoke, the panel will automatically
restore when the smoke clears.
Alarm and trouble conditions are determined by the elec-
tronics in the detector head, which also automatically per-
forms drift compensation. Normal sensitivity is 2.4% per
foot. When the sensor is in alarm, the LEDs in the sensor’s
housing will light continuously.
The XP95-DM is connected to a two-wire signal line circuit
(SLC) carrying both XP95 protocol data and a 17 to 28
VDC supply voltage. The XP95-DM is insensitive to loop
polarity. A remote LED indicator may be connected.
