Installer manual
2. 1 . Operation
Introduction
The device can be connected to an alarm plant via row electrical connections that
can reach a maximum distance of 200 meters.
The smoke detector consists of a sturdy plastic container where the electronic
control circuit, the piezoelectric siren and the smoke generator accompanied by
its own activation circuit are housed inside.
The electronic circuit is equipped with an 8-pole removable terminal block where
the following connections are present:
ʂ VCC
ʂ Input Start Smoking
ʂ Input Start Siren
ʂ Tamper Output / Anti-tear
ʂ Output Out-of-time
ʂ Output
ʂ GND
The device allows an easy installation by indicating in real time the state of the
apparatus by lighting a multicolored LED.
In order to avoid involuntary activations of the smoke generator during installation,
the apparatus recognizes the tamper opening and after 15 seconds enters "TEST
and MAINTENANCE" mode. At this stage, the activation of the smoke generator is
disabled and any accidental activation is diverted to the siren sound. This function
can also be used as a system test. The exit from the "TEST and MAINTENANCE"
state is obtained 15 seconds after closing the container with the TAMPER and the
anti-tear (if enabled) in the resting state. A power range of 3Vcc to 15 Vcc and a
low absorption of about 200 uA at rest, allow you to use the device in any security
system.
