FIRE DETECTION, ALARMS, AND SUPPRESSION SYSTEMSIn clues, the following (_ words) indicates the number of words without spaces in the answer

Across

2 A connection for sprinklers that consist of a siamese or a large-diameter

connection that is connected to a clappered inlet (2 words)4 These are limited in a fire because the fire near a sprinkler is extinguished orcontrolled in the early growth stage (2 words)

7 These discharge water after the release of a cap or plug that is activated bysome heat-responsive element

9 The type of sprinkler system which contains water under pressure at all times,allowing the system to immediately discharge when needed (2 words)

11 This is usually located immediately under the sprinkler alarm valve, the dry-pipe or deluge valve or outside the building near the sprinkler system that itcontrols (2 words)

13 A mechanism designed with fusible links with increased surface area in orderto collect the heat generated by fire, faster than other sprinkler mechanisms (2words)

14 A sprinkler head used in a small rood where the branch line runs along thewall

17 The type of sprinkler system that is pitched to allow the pipes to drain whennot in use and replaced by air under pressure

18 A sprinkler head with a ultra high temperature classification has this colorcode

19 A sprinkler head with a temperature rating of 175 to 225 degrees F. have atemperature classification of this21 A smoke detector that use a tiny amount of radioactive material to ionize air

molecules as they enter a chamber within the detector22 These may be inserted between the discharge orifice and the deflector to stop

the flow of water from a sprinkler head23 This holds the levers together in a sprinkler head until it is melted during a fire

(2 words)25 A sprinkler head that sits on top of a pipe and sprays up into the deflector that

breaks up the stream and redirects it towards the floor26 A smoke detector that utilizes a potoelectric cell and a beam of light as essential

components in detecting that a fire may have initiated

Down

1 A common indicating valve that has yoke on the outside with a threaded stemthat controls the opening and closing of the gate (4 words)

3 A sprinkler head with a extra high temperature classification has this color


3/4

code5 A alarm that warns that water is moving through a sprinkler system (2 words)6 The valve utilized to turn off the water supply to a sprinkler system so that

sprinklers can be replaced, and maintenance can be performed on the system(2 words)

8 A smoke detector that is sometimes called a visible products-of-combustiondetector

10 A sprinkler head with a temperature rating of 325 to 375 degrees F. have atemperature classification of this (2 words)

12 The __ __ of building occupants is enhanced by the presence of a sprinklersystem because it discharges water directly on a fire when it is relatively small(2 words)

15 A heat detection device that uses a little glass vial containing a liquid with asmall air bubble, which is designed to break when the liquid is heated to apredetermined temperature, thus activating the device (2 words)

16 These press against the frame and a cap over the orifice in the frame whichholds back the water from exiting a sprinkler head20 A sprinkler head that extends down from the underside of piping24 A sprinkler head with a intermediate temperature classification has this color
