Còi báo cháy loại nhỏ VF4027-10

The VF4027 Series mini-horn is a high quality remote signaling appliance that offers dependable remote annunciation. The VF4027 is listed for use with both filtered and unfiltered power.
With the VF4027 a jumper is provided to select either the continuous tone or the temporal 3 evacuation tone.
The VF4027 can be used on the same sync circuit (VF4009 Series Control Module) as other VES signals. The VF4027 appliances
are UL 464 listed for use with fire protective systems and are warranted for three years from the date of purchase.
NOTES Operating temperature – Indoor Use Only. Indoor: 32° to 120°F (0° to 49°C). The sound output for the temporal 3 tone is rated lower since the time the horn is off is averaged into the sound output rating. While the horn is producing a tone in the temporal 3 mode its sound pressure is the same as the continuous mode.
