IVORY
PASSIVE INFRARED DETECTOR
WITH MIRROR OPTICS
ivory_en 01/15
The IVORY detector allows detection of motion in the protected area. This manual applies to the
detector with electronics version 2.3 or newer.
1. Features
•
High-quality segmented mirror.
•
Advanced digital signal processing.
•
Digital temperature compensation.
•
Adjustable detection sensitivity.
•
Built-in EOL resistors.
•
LED to indicate alarm status.
•
Remote LED enable/disable.
•
Alarm memory.
•
Supervision of detector signal path and supply voltage.
•
Tamper protection against cover removal.
2. Description
After motion is sensed by the detector in the coverage area, the alarm relay contacts will open for
2 seconds.
Supervision features
In the event of the voltage drop below 9 V (± 5%) for more than 2 seconds or the signal path
failure, the detector will signal a trouble. The trouble is indicated by the activation of alarm relay
and the steady red light of LED indicator. The trouble signaling will continue as long as the
trouble persists.
Remote LED enable/disable
The LED can be enabled/disabled remotely when the jumper is placed across the LED pins in
OFF position. The LED terminal is provided to allow remote LED enable/disable. The LED is
enabled, when the terminal is connected to the common ground, and disabled, when the terminal
is disconnected from the common ground. You can connect to the LED terminal an OC type
control panel output programmed e.g. as the
S
ERVICE MODE STATUS
,
BI
SWITCH
or
Z
ONE TEST
STATUS
.
Alarm memory
If the LED is enabled, the detector can signal the alarm memory. The MEM terminal is provided
to allow the alarm memory enable/disable. The alarm memory is enabled, when the terminal is
connected to the common ground. The alarm memory is disabled, when the terminal is
disconnected from the common ground. If the alarm memory is enabled and an alarm occurs, the
LED will start blinking. Indication of the alarm memory will continue until the alarm memory is
enabled again (the MEM terminal is connected to the common ground). Disabling the alarm
memory will not stop the alarm memory indication. You can connect to the MEM terminal an OC
type control panel output programmed e.g. as the
A
RMED STATUS
.
