Astra-421 Ver. RF

Wireless Optoelectronic Smoke Detector

Operation Manual

This operation manual is intended for studying principle of
operation, correct use, operating conditions and maintenance of
the wireless optoelectronic smoke detector «Astra-421» ver.RF
(hereinafter «detector») (figure 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 intended for

detecting fire followed by smoke
spreading, forming and transmit­ting «Fire» notification to the re­ceiver «Astra-RVA» (hereinafter
«receiver») of wireless intrusion/fire
detection and alarming system Ob-

server-1.

1.2 The detector supports 3 operat-

ing frequencies.

1.3 Electric power is supplied by a

lithium-thionyl-chloride battery cell
standard size AA, voltage 3,6 V
(included in delivery set).

2 Principle of Operation

The principle of operation of the detector is based on register­ing infrared radiation (hereinafter IR) that is reflected from
smoke particles in the smoke chamber by a photodetector. Fur­ther the electric signal formed by the photodetector is amplified
and sent to microcontroller in order to analyze the smoke densi­ty value. The detector generates «Fire» or «Warning» notifica­tion in accordance with a specified operating algorithm.

5 Structure

Constructively the detector consists of a removable electronic
unit and a base (figure 2).

Figure 2

Inside the electronic unit is a smoke chamber and printed circuit
board (PCB) with radio elements and photodetector.
Mounted on PCB is a LED for checking the detector`s operability.
The design of the detector provides for its installation on the
ceiling.

Note - It is not recommended to disassemble the electronic unit
of the detector, as it may damage the detector’s tuning.

7 Operation Modes

The detector provides for
«Test» and «Autotest»
operating modes, intended
for testing electronic circuits
of the detector.

7.1 The «Test» mode is

activated when reading a
coded message by LED sent
from laser tester «Astra-
941» (figure 3).
In 5 sec after reading the
message, the detector must
output the «Fire» notification

- if the detector operation is
normal, or «Failure» - in
case of a failure.

Figure 3

Note - Laser tester «Astra-941» is optional and delivered sepa-
rately.

7.2 The «Autotest» mode is activated by the detector auto-

matically every 24 hours. At that the operation threshold is ad­justed depending on the environment and the «Test» mode is
activated. Upon successful completion of the test notification is
not generated. In case of failure, «Failure» notification is
generated.

8 Pre-starting Procedure

8.1 After transportation in conditions differing from those of

operation, keep the detector unpacked for 4 hours in the ex­pected operating conditions.

ATTENTION! Check correspondence of frequency carrier
of the detector and the receiver.

8.2 Running Detector

Attention! Lithium-thionyl-chloride batteries have an effect of

«passivation» to provide the possibility of long-term storage. To
provide battery normal operation after long-term storage, hold
an «activation» procedure.

Step-1

Place the detector on-the­spot.
Turn the electronic module
counterclockwise.
Remove the electronic unit
from the detector`s base.

Step-2

Install the battery cell.
Switch the detector ON by in­stalling jumper on power plug.

Step-3

To replace battery:

- switch the detector OFF;

- remove the old one;

- after no less than 20 sec install the new battery.
When installing into detector the battery is automatically
«activated» and checked. The LED lights red (less than 20
sec.)
After checking:
 In case the LED flashes 2 times successively with fre-
quency once per 10-15 sec («Low supply voltage»), remove
jumper, close the positive and negative poles of the battery
for 2-3 sec with a piece of wire and repeat switching by in­stalling jumper back after at least 20 sec.
 In case the LED flashes with frequency once per 1 sec
(«Standby mode») and notification «Power failure» is not
appears, the battery is considered as useful.

8.3 Registration Procedure

The detector registering in the receiver memory occurs at the
moment of powering up.

Step-1

Place the detector on-the­spot.
Turn the electronic module
counterclockwise.
Remove the electronic unit
from the detector`s base.

Step-2

Switch the detector OFF by
removing jumper from
power plug

Step-3

Set the registration mode on a receiver according to proce­dure described in the «Astra-RVA» operation manual or the
Observer-1(2) system operation manual (available for free
downloading from www.controlex.eu) or Quick Start Guide.

Step-4

Switch the detector ON by in­stalling jumper on two pins of
power plug

Step-5

Make sure the registration procedure is completed according
to procedure described in the «Astra-RVA» operation manual
or the Observer-1 system operation manual (available for
free downloading from www.controlex.eu) or Quick Start
Guide.

 Once the registration procedure completed successfully

reassemble the detector.

- superpose the electronic unit and the base.

- rotate the electronic unit until matching the projections of
the electronic unit with the base` grooves.

- press the electronic unit to the base and rotate clockwise

until it stops.
 Once the registration procedure failed remove jumper
from the power plug and after at least 20 sec repeat
steps 3-5.

Step-6

After successful registration of the detector, for long term
storage before its installation, it is allowed to switch the de­tector OFF by removing jumper from power plug.

When installing the detector on-site there is no need to re­register it in the memory of the same receiver, if the memory
of the receiver has not been cleared.
