Automatically help remove smoke from a house on fire to give people extra time to leave. Can be activated by a Fire Alarm System, but must have its own power source to operate. Check Fire Alarm System to see if it has a Smoke Detector. Controlled by a built-in T hermostat to protect attic water pipes from freezing. Volt DC current can be used.
Some codes require a battery backup for smoke detectors.
If a Power Supply is used as a power source, you may need to install a battery operated smoke detector also, to comply with codes. A 12 or 24 Volt DC battery with a trickle charger that will keep the battery fully charged without overcharging can be used. Body - 26 Ga. Galv. Place the Miracle Vent on top of the Plastic Louver.
