Component Identification - urmet 1051/101 Installations-, Programmier- Und Gebrauchsanleitung

ENGLISH
The 1051/101 and 1051/102 are detectors with passive infrared (PIR) motion sensor capable of detecting movements in an assigned
area and indicate them to the control unit to activate the intrusion alarm. The base of the detector is provided with holes for installing it
on a flat surface or in a corner.
The detector has a single tamper switch which is activated when the lid is opened, or if it is detached from the wall. Furthermore, it can
send a warning to indicate a communication problem or flat battery conditions. The detector was designed to operate with a detection
range of 12 metres when it is mounted at 2 metres from the ground.
The 1051/102 version also allows use in presence of small and medium-sized animals, within 7 meters of range, without these
generating alarms.

Component identification

1. Test/Learning button and LED indicator
The Test button is used to test wireless communication performance and to carry out the learning
procedure of the device by the control unit. The LED indicator is used to indicate the system state.
2. Battery isolator
3. Tamper switch
The tamper switch protects the detector from unauthorised opening of the cover, or by forced
detachment from the wall where the device is installed.
4. Adapter for corner mounting
5. Pulse counter / increased sensitivity jumper (JP3)
- If the jumper is set to OFF (jumper removed or positioned on only one pin), the detection
sensitivity is at normal level.
- If the jumper is set to ON, the detection sensitivity of the detector is maximum (default).
Sleep Time
The detector has a "sleep time" of approximately 1 minute to save energy. After having transmitted a
detected movement, the detector will not transmit again for 1 minute; any further movements detected
during the sleep period will extend the sleep period by another minute. In this way, continuous movements
in front a detector will not drain the battery unnecessarily.
Supervision function
If the function is enabled, when the detector is in normal operation mode, it runs a periodically self-
diagnostic test, transmitting a supervision signal at constant intervals.
A supervision alarm is generated if the control unit does not receive supervision signals transmitted by a
given detector for a predetermined time.
Sensitivity Increase function
This function can be used to increase detection sensitivity. To increase detection sensitivity, insert jumper
JP3 (ON position). Use position OFF to maintain normal sensitivity.
In the 1051/101 version the default position is OFF, in the 1051/102 version the default position is ON.
Test mode
The detector can be set to Test mode by pressing the Test button on the front cover for a few seconds. In
Test mode the sleep timer will be deactivated and the LED indicator will blink whenever motion is detected.
Whenever the Test button is pressed, the detector transmits a test signal to the control unit to test the wireless communication range
and goes to Test mode for 3 minutes. It automatically exits Test mode after 3 minutes and goes back to normal mode if, during this time,
the test button is no longer pressed.
LED indicator
In normal operating mode, the LED indicator blinks to indicate that signals are being transmitted in the following situations.
When powered, flashes for 30 sec (initialisation phase).

When movement is detected in flat battery conditions.

When the cover is opened and the tamper switch is actuated.

When movement detected if the tamper alarm condition persists.

When motion is detected in Test mode.

When the Test button is pressed in tamper alarm conditions or if the battery of the detector is flat.

The LED does not blink if the tamper switch and the battery detector are normal and not in Test mode. The LED blinks rapidly twice to
confirm reception by the control unit.
Battery
The motion sensor is powered by a CR123A lithium battery. The detector can detect low battery state. When a flat battery is detected,
a signal is sent to the control unit together with the normal signal transmission for the control unit to view the corresponding state.
The battery is installed at the factory with the isolator inserted.

 While replacing the batteries, after having removed the flat batteries, press the tamper button twice to discharge the
device completely before inserting the new batteries.
Preparation
Extract the battery isolator to activate the battery.
