Heat detectors are available in 1350F and 2000F <br />temperature ratings. <br /> <br />Rate-of-rise elements detect heat by quickly responding to rapid <br />temperature increase. HD-600 detectors use the same reliable <br />pneumatic rate-of-rise element used in former models, but offer <br />added aesthetic appeal. The pneumatic rate-of-rise element <br />responds to a rapid rise in temperature, approximately 150F <br />(80C) per minute, by expansion of air within the sealed chamber <br />faster than it can escape through a calibrated vent. The result- <br />ant increase in pressure depresses the diaphragm, causing the <br />electrical contact to close the circuit. HD-600 rate-of-rise units <br />have a wide spacing allowance of 50-foot centers. See Specifi- <br />cation Table for details. <br /> <br />Fixed-temperature elements react to heat by responding to a <br />specific temperature setting. The fixed-temperature element <br />uses a fusible alloy. When activated, the external heat collector <br />drops away to provide quick visual confirmation that the element <br />has operated. <br /> <br />The units protrude only 1-3/8" from the ceiling surface with a <br />junction box mounting. They have pleasing contours and an all- <br />white finish that conforms to ceiling aesthetics. <br /> <br />FEATURES <br />. Rate-of-rise and fixed-temperature. <br />· One- or two-circuit, normally open. <br />. Easy installation. <br />· Low-profile design. <br />. Visual indication. <br />. Operation testing. <br /> <br />INSTALLATION <br /> <br />Each detector includes a patented reversible mounting plate. In <br />one position, it easily attaches to a 3-1/4" octagon box, <br /> <br />In reverse, the plate can be used for open wiring without a <br />junction box. A 1/4" space between detector and mounting <br />surface allows for wire connections. All mounting screws are <br />concealed. <br /> <br />The detector attaches simply to the mounting plate with a push <br />and twist motion. No special tools are required. <br /> <br />The mounting plate is molded of white self-extinguishing thermo- <br />plastic rated at 1050C. The plate is extremely strong, yet adapts <br />to uneven mounting surfaces. <br /> <br />October 20, 1995 <br /> <br />@ <br /> <br />g-: I' ON3AS.AY (HD621, HD601/HD602) <br />I .
