QUESTION 
--------  
 
Mike,

Horn/strobe booster panels located in a warehouse area with 30 foot 
ceilings will require smokes above the panel.  Should we mount the 
detectors at the bottom of the beam above the panel at 30 feet, or are 
we allowed to mount the detectors near the panel at a much lower 
height? 
 
Bruce A. 
Lexington, KY 
 
ANSWER 
------ 
 
Hello Bruce, 
 
NFPA 72-2007 added language to address your situation, especially in 
Annex A, which allow smoke detectors to be installed within 6' 
measured vertically from control equipment in high-ceiling 
applications: 
 
4.4.5* Protection of Fire Alarm System.
In areas that are not continuously occupied, automatic smoke detection 
shall be provided at the location of each fire alarm control unit(s), 
notification appliance circuit power extenders, and supervising 
station transmitting equipment to provide notification of fire at that 
location.
Exception No. 1: Where ambient conditions prohibit installation of 
automatic smoke detection, automatic heat detection shall be permitted. 
Exception No. 2: Fully sprinklered buildings shall not require 
protection in accordance with 4.4.5.
 
Annex A:
--------
A.4.4.5 The fire alarm control unit(s) that are to be protected are 
those that provide notification of a fire to the occupants and 
responders.  The term fire alarm control unit does not include 
equipment such as annunciators and addressable devices.   Requiring 
smoke detection at the transmitting equipment is intended to increase 
the probability that an alarm signal will be transmitted to a 
supervising station prior to that transmitting equipment being 
disabled due to the fire condition. 

CAUTION:  Exception No. 1 to 4.4.5 permits the use of a heat detector 
if ambient conditions are not suitable for smoke detection. It is 
important to also evaluate whether the area is suitable for the 
control unit.
Where the area or room containing the control unit is provided with 
total smoke-detection coverage, additional smoke detection is not 
required to protect the control unit.  Where total smoke-detection 
coverage is not provided, the Code intends that only one smoke 
detector is required at the control unit even when the area of the 
room would require more than one detector if installed according to 
the spacing rules in Chapter 5.  The intent of selective coverage is 
to address the specific location of the equipment.

Location of the required detection should be in accordance with one 
of the following:   
(1) Where the ceiling is 4.6 m (15 ft) in height or less, the smoke 
detector should be located on the ceiling or the wall within 6.4 m 
(21 ft) of the centerline of the fire alarm control unit being 
protected by the detector in accordance with 5.7.3.2.1.
(2) Where the ceiling exceeds 4.6 m (15 ft) in height, the automatic 
smoke detector should be installed on the wall above and within 1.8 m 
(6 ft) from the top of the control unit.
 
Best regards,
 
Mike
