DETECTORS
• The detector consists of three basic components: the bracket, CUP -ON STYLE - PART NO. 56837 AND 56838
linkage, and fusible link. (Fusible links are not included and must '
be ordered separately.) The bracket holds the entire assembly 1
to the mounting surface. The linkage is used to support the
fusible link. The fusible link is designed to separate at a specific LINKAGE BRACKET

temperature and release the wire rope, thereby actuating the LINK
regulated release mechanism. f
There are three styles of detectors available: the clip -on style,
the hinged style, and the scissor style.
The clip -on style allows the wire rope to be strung completely HINGED STYLE - PART NO. 15373 AND 15375
through the detection system conduit and brackets first and the
detector linkage assemblies are then clipped on later.
The hinged style detector requires the wire rope to be strung •
to the detector bracket, and then "threaded" through the linkage UNKAGE BR
assembly before continuing to the next detector bracket. Fu sIBLE
The scissor style allows the wire rope to be strung completely - LINK -
through the detection system conduit and brackets first and the =I r
detector linkage assemblies are then clipped on later. 16.=.71 -
Each style of detector consists of two types of assemblies: •
The Terminal Detector (Part No. 56838, 15375, or 417368) SCISSOR STYLE - PART No. 417368 AND 417369
includes a test link and is placed last in a series of detectors.
This detector is sometimes referred to as the end-of -line detector BRACKET
and is thus named because it is at the point at which the wire UNKAGE
rope "terminates," or is anchored at the detector bracket. Only
one terminal detector is required per detection system. FUSIBLE
The Series Detector (Part No. 56837, 15373, or 417369) is UNK
any detector located in -line between the regulated release
assembly and the terminal detector. V

The R -102 system uses two 1W Nozzles (Part No. 56927) for (81 x 86 cm)
overhead chain broiler protection. The nozzle tip is stamped with
1W, indicating that this is a one -flow nozzle and must be counted FIGURE 48
as one flow number.
Overhead protection is only available for chain broilers with The nozzles may vary in position as long as they are evenly

(81 x 86 cm).
Example No. 1 - Internal broiler size is 24 in. long x 20 in. 1,-- __I
wide (61 x 51 cm), with an opening of 16 in. x 16
in. (40.6 x 40.6 cm).
To determine minimum opening size, multiply the t�
internal length and the internal width by 0.6:
Length of opening - 24 in. x 0.6 = 14.4 in. (61 cm
x 0.6 = 36.6 cm)
Width of opening - 20 in. x 0.6 = 12.0 in. (51 cm
x 0.6 = 30.5 cm)
The minimum allowable opening for overhead pro- TOP VIEW TOP VIEW
tection would be 14.4 in. x 12.0 in. (36.6 x 30.5 cm).
This example would be acceptable for overhead FIGURE 49
protection. .
Example No. 2 - Internal broiler size is 30 in. long x 24 in.
wide (76 x 61 cm) with an opening of 22 in. x 12 in.
(56 x 30 cm).
To determine minimum opening size, multiply
internal length and internal width by 0.6:
Length of opening - 30 in. x 0.6 = 18.0 in. (76 cm
x 0.6 = 45.7 cm)
Width of opening - 24 in. x 0.6 = 14.4 in. (61 cm
x 0.6 = 36.6 cm) •
Minimum allowable opening for overhead protection .
- would be 18 in. x 14.4 in. (45.7 x 36.6 cm).
Because this broiler has an opening of 22 in. x 12
in., the 12 in. width is below the minimum allowable
calculated dimension of 14.4 in. (36.6 cm) and there-
fore would not be acceptable for overhead
protection.

If the fryer does not have a drip board, the maximum hazard
size is 15 in. x 14 in. (38 cm x 36 cm), or a maximum dimension .
of 15 in. (38 cm) and a maximum area of 210 sq. in. (1355 sq.
cm). If the fryer has a drip board, the maximum hazard size is
21 in. x 14 in. (53 cm x 36 cm) or a maximum dimension of 21
in. (53 cm) and a maximum area of 294 sq. in. (1897 sq. cm).
The maximum fryer pot size must still not exceed 15 in. x
14 in. (38 cm x 36 cm). The nozzle must be aimed at the center
of the hazard area.
The R -102 system uses two different style nozzles for the pro-
tection of fryers.
1. High Proximity Applications: 27 to 47 in. (68 to 119 cm)
above the top surface of fryer. See Figure 31a and Figure
31 b.
The 230 Nozzle (Part No. 418117) is used for high prox-
imity applications. The nozzle tip is stamped with 230,
indicating that this is a two-flow nozzle and must be counted
as two flow numbers.
When using this nozzle for fryer protection, the nozzle tip
must be positioned anywhere along or within the perimeter
• - of the maximum hazard area and angled to the center.
