Smoke detectors
are designed to provide early warning of developing fires at
a reasonable cost. They monitor the air and can sense smoke,
providing precious minutes for you and your animals to
escape before a fire spreads. Early warning fire detection
is best achieved by the installation of one smoke detector
for every 750 square feet.
Model 2012HA is a low-voltage photo electronic smoke
detector designed for open area protection in a residential
buildings, barns and stables. It has a built-in relay which may be used to
activate auxiliary devices such as bells, horns and door
closers. The relay contacts automatically close 8 seconds
after the detector goes into alarm. A piezoelectric
horn in each detector produces an audible 85 dBA temporal
tone evacuation signal when a detector alarms or an
interconnected detector alarms. This temporal tone
evacuation signal complies with ISO8201. The signal consists
of 3 beeps each, 5 seconds apart, followed by 1.5 seconds of
silence. These detectors can be interconnected for a system
of up to 12 smoke detector per barn so when one smoke
detector sounds its evacuation signal it causes the other
connected detectors to sound as well.
