Fixed Temperature Principle of Operation
In a slow developing fire, the temperature may not
increase rapidly enough to operate a rate-of-rise
element. Therefore, a fixed-temperature principle of
operation is needed.
The detector utilizes a fixed-temperature element
made of fusible alloy and is of the non-restorable
type.
The fusible alloy will melt and activate the detector
when the surrounding air rises above the preset
level of 135°F or 194°F.
The external heat collector drops away when the
detector is activated therefore giving a quick visual
confirmation that the detector has alarmed.
Installation
Each detector includes a thermoplastic, reversible
mounting plate. In one position, it easily attaches to
a 4" octagon junction box, 3" octagon box or
plaster ring.
In reverse, the plate can be used for open wiring
without a junction box. A
1
/4" space between
detector and mounting surface allows for wire
connections. All mounting screws are concealed.
The detector simply attaches to the mounting
plate with a push-and-twist motion ─ no tools
are required.
