Crow BS-1 - User Manual

BS-1 SIREN
High Power Siren With
Battery Back-up and Flashlight
INSTALLATION INSTRUCTIONS & USER MANUAL
BS-1 Features
The BS-1 siren is a new generation of professional
high power acoustic siren with battery back-up and
flashlight, which include all performance and reliability
for security alarm system.
Features:
Outdoor battery back-up siren with flashlight.
Double housing: External –3mm plastic
PC with UV, Internal – 0.8mm metal.
Continuous frequency modulated sound.
Tamper protection in 3 ways – Screw or
Cover opening or tearing housing from the wall.
Positive and negative alarm trigger inputs.
Trigger input to activate only the flashlight.
Siren period can set as follow trigger or 3 min
cutoff
Selector for lamp or xenon
Alarm by main power failure.
Protecting against totally battery discharge.
Plug Terminal for easy Installation.
Environmental immunity.
Functional Description Alarm Trigger:
The alarm can be triggered by applying high or low
voltage to the “GO+” or “GO-“ inputs terminals
respectively. The sound and flashlight triggered
together.
Alarm siren duration depended on the Trigger selector
state:
F.T- Follow Trigger .
TMR- siren cutoff after 3 minutes,this state is
recommended in order to avoid violation of any
local regulations.
Flash Trigger:
The flashlight can be triggered by applying “low”
level to “FL-“ terminal. Flash duration is not limited
and the time of flashlight is set by control panel - as
long as trigger available the flashlight will be active
Tamper:
The tamper is normally closed while the housing is
closed with the screw, so in this state the tamper
terminals are shorted (0 Ohm) .The tamper will open
while opening the screw or by tearing the housing
from the wall.
Note: It’s essential to screw the tamper socket to
the wall properly.
Power Failure:
On Power Failure the siren and flashlight are
triggering, until power supply is restored or time out
period (5 minutes) expires.
Battery Protection
The Siren is supplied with protection against totally
battery discharge by cutting off the siren, when
voltage level falls down to less then 8Vdc.
Installation Instructions
1. Choose the mounting location for the siren –
the wall must be even and free of holes and
excessive protrusions.
2. Mark and drill 5 holes with the help of the attach
drill pattern plate (4holes for the housing base
and 1 for the tamper).
Note:Take a consideration about the wires
inputs in the housing base.
