By-alarm IP54 curtain radio frequency detector for outdoor use, with
dual technology, to protect entrances and openings such as doors,
windows, covered terraces, corridors and French doors, surface
mounting, powered by 1 3 V CR2 lithium battery (supplied).
The By-alarm dual technology curtain detector is a compact two-directional radio
device that is particularly suited to protecting both internal and external doors and
windows provided it is not directly exposed to rain or sunlight. The internal electronics
are tropicalised to ensure correct operation in all temperature and humidity condi-
tions. These characteristics make it suitable for installation to protect well-defined
areas, as it creates a very small curtain barrier (approx. 7°) and an adjustable range
from 2 to 12 m. The detector is powered by a lithium battery and requires no wiring.

LED signalling, front of board
•
Red
: Burglar alarm in both TEST MODE and standby (if enabled)
•
Amber
:
- Microwave detection in TEST MODE
- "Low battery" warning in standby (if enabled)
•
Green
: Infrared detection in TEST MODE
BATTERIES
The detector is powered by a 3 V CR2 lithium battery. When the battery reaches the
level of 2.8 V, the "low battery" signal is sent to the control panel; from this point on,
the device remains operational for approximately another 30 days within which you
need to change the battery.
• To change the battery the keypad is set in programming mode and then the flat
batteries are replaced by opening the enclosure. After changing them, exit pro-
gramming.
• To ensure a longer battery life, we recommend using batteries with an expiry date
5 years after the date of replacement.
CAUTION: Danger of explosion if the battery is replaced with one of the wrong
type.
DETECTOR CONFIGURATION
Programming the device requires configuring several parameters that affect the oper-
ation of the detector, the supervision method, the transmission power and the LEDs.
DIP-switch
•
Dip no. 1
: in ON “low battery” warning setting.
•
Dip no. 2
: Inhibition length; in ON 6 min and in OFF 3 min.
•
Dip no. 3
: in ON intrusion alarm warning in standby (the red led comes on also with
low-consumption detectors).
•
Dip no. 4
: TEST MODE; in ON it is in test mode (no inhibition and LEDs active) and
when switched to OFF it exits the test phase after 3 min.
General configurations
The detectors are configured via three menus; the single options are accessed and
set via the push-buttons on the back of the board:
PROG
: navigation push-button.
RESET
: push-button for restarting the device.
SELECT
: push-button for menu selection.
TAMPER
: push-button for setting the parameters.
Before configuring the detector it is always necessary to set the relevant param-
eters.
SETTING PARAMETERS
After correctly powering up the device, keeping the
PROG
push-button pressed,
press for 1 s and then release the
RESET
button.
The three LEDs on the back of the board will emit a fast blink and then go out; this
indicates access to Menu 1. Lastly, release the
PROG
button.
Selecting the desired menu
To select the desired menu, briefly press the
PROG
button; each time it is pressed
the LEDs change status, showing the related menu item as shown in the table
below:
