General  

Description

The TYCO Model TFP PH2, 5.6 K-fac-

tor, Institutional Pendent Sprinklers are 

standard response standard coverage, 

fusible solder type spray sprinklers 

designed for use in areas such as cor-

rectional, detention, and mental health 

care facilities.
The unique features of the Model TFP 

PH2 provide a tamper resistant sprin-

kler design that helps eliminate the 

opportunity for individuals to injure 

themselves or others with the compo-

nents of a fire sprinkler. At the same 

time, the Model TFP PH2 optimizes an 

aesthetically appealing flush design 

that conceals most of the operating 

parts.

Operation

In the standby condition, the design 

of the Model TFP PH2 is such that a 

dynamic load of 80 lb (36 kg) or more 

applied to the linkage mechanism will 

release the sprinkler. Also, when prop-

erly installed, the escutcheon is held 

fast to the ceiling to deter its removal. 

The shape of the escutcheon cannot 

be easily grasped, which further deters 

tampering.
A fusible solder operating element 

secures the linkage mechanism of the 

Model TFP PH2. When the rated tem-

perature is reached, the solder melts, 

releasing the linkage mechanism that 

holds the sprinkler closed. This allows 

the deflector to extend downward and 

water to flow.
