Astra-361 Version RF
Wireless Water Leak Detector
Operating Manual
Rev. 361rk-v1_0_en
The present operation manual is intended for studying
operat-
ing principle, correct usage, storage and maintenance of wire-
less water leak detector Astra-361ver. RF (hereinafter referred
to as “
detector
”) (Fig. 1).
The manufacturer reserves the right to make alteration regarding
refinement of the product without prior notification. All changes
will be imported into new edition of the operation manual.
1 Function
1.1
The detector is designed for detection
of water leak events (except for distilled wa-
ter), forming an
“Alarm” notification and
sending it to receiver Astra-RVA (hereinaf-
ter
“RVA”) of wireless intrusion and fire de-
tection and alarming system Observer I.
1.2
The detector supports three operating
frequencies.
1.3
The detector is powered by a battery of
CR2450 type (voltage
– 3.0 V) or batteries
of comparable characteristics and design.

4 Structure
Fig. 2
Structurally, the detector is designed as a unit consisting of a
base and a removable cover (Fig. 2). The cover is attached to
the base with screws.
The unit houses a printed circuit board with radio elements.
An indicator mounted on the circuit board provides for detector
operability supervision.
Contact pads are located on the detector body.
