Pittway ADEMCO QUEST 2120 Quick Start Manual

QUEST 2120-INST 12/97
QUEST 2120
Microwave/PIR
Intrusion Detector
Specifications
Input Power: 9 to 15 VDC, 16 mA DC nominal (up to 48 mA DC
during walk testing or trouble conditions).
Standby Power: No internal standby battery. Connect to DC power
sources capable of supplying standby power. Sixteen
mA-H required for each hour of standby time needed.
Alarm Relay: Silent operating Normally Closed reed relay. Contacts
rated 3 watts, 125 mA, 28 VDC maximum for DC re-
sistive loads, and protected by a 4.7 ohm, 1/2 watt
resistor in the common "C" leg of the relay. Do not use
with capacitive or inductive loads.
Operating
Temperature: -40° to +120°F (-40° to +49°C). For U.L. Listed Re-
quirements, the temperature range is +32° to +120°F
(0° to +49°C).
Microwave
Frequency: 10.525 Ghz ± 25 MHz.
Coverage: 20 ft. by 20 ft. (10.7 m by 10.7 m).
Internal
Pointablility: +2° to –10° Vertical, ±10° Horizontal.
Tamper: Normally Closed (with cover on). Contacts rated at
28 VDC, 0.125 A max. Connect tamper circuit to 24
hour protection circuit.
Options: QUEST SB2 swivel bracket. (Use of a bracket may
reduce range and dead zone area).
NOTE: The protected coverage area is where the microwave and PIR
patterns overlap.
NOTE: To use the optional Look Down Zone, the Mask must be
removed from the Look Down Lens. See Figure 2.
Remove the black mask only. Do not attempt to remove
the white lens assembly. Do not remove the mask for pet
applications.

Installation Hints
• Never install the detector in an environment that causes an alarm con-
dition in one technology. Good installations start with the LED OFF
when there is no target motion. It should never be left to operate with
the tri-color LED in a constant or intermittent green, yellow, or red con-
dition.
• Point the unit away from outside traffic (roads/alleys). Remember: Mi-
crowave energy will pass through glass and most common non-metal-
lic construction walls. Avoid installations where rotating machines (e.g.,
ceiling fans) are normally in operation within the coverage pattern.
• Point the unit away from glass exposed to the outdoors and objects
that may change temperature rapidly. Remember: The PIR detector
will react to objects rapidly changing temperature within its field-of-
view.
• Eliminate interference from nearby outside sources.
Special Instructions
for Installations Containing Pets
The QUEST 2120 will provide reasonable protection from nuisance
alarms caused by the following sources:
• A dog up to 100 pounds.
• Two dogs, up to 60 pounds each.
• Up to 10 cats.
• Multiple small rodents, such as rats.
• Random flying birds.
To take full advantage of the QUEST 2120's Pet Exclusion Technology,
the following guidelines should be followed:
• Mount the center of the detector 6 1/2 feet high and adjust the vertical
angle to -9°.
• Set the PIR sensitivity for standard (STD).
• Mount where animals cannot come within six feet of the detector by
climbing on furniture, boxes, or other objects.
• Do not aim the detector at stairways that can be climbed by an animal.
• Adjust the microwave range for the minimum acceptable coverage for
the room in which the detector is installed. Never install with the micro-
wave range exceeding 20 feet.
NOTE: This nuisance protection has not been verified by Underwriter's
Laboratories, Inc.
