Backup Outdoor Siren OS-300 & OS-305
Description
The OS-300 (305) is a high powered electronic
siren and flashing light with a rechargeable battery
back up. All functions of this siren are controlled by
a built in microcontroller. It permanently performs
self tests and it also checks connection with an
alarm system. The siren has a digitally balanced
loop (E.O.L. resistor) input as a trigger. This input is
able to recognize any manipulation on siren's wiring.
The siren is also triggered if power supply
interrupted. An optional trigger delay timer includes
a feature that makes the siren wait 15 seconds
before sounding alarm. The microcontroller controls
the back-up battery charging (built in DC/DC
converter).
The siren is protected by double casing. Outside is
UV and weather resistant plastic, inside there is a
metal cover. This provides an excellent protection
from the elements and physical tampering. Two
tamper switches are built into the unit. They
recognize removing the cover from the unit or the removing the siren from the wall.
Model: OS-300 is equipped with a magneto-dynamic horn siren
OS-305 is equipped with piezo-electronic siren
LED indicator confirms the siren's auto testing (=siren is ready).
