rise temperature rating at spacing see Note A 50 ft 15.2 m distance from wall see Note B 25 ft 7.6 m detectors have one normally open contact rated as follows 3.0 A at to 125 Vac 1.0 A at 6 to 24 Vdc 0.3 A at 125 Vdc and 0.1 A at Vdc A Maximum detector coverage has been determined by UL to detection time equal to sprinkler devices spaced at 10 ft 3 m 100 sq ft area on a smooth ceiling 15 ft 9 in 4.8 m high ceilings can adversely affect detection time In some instances detection may be obtained by reducing the spacing between B Maximum distance shown is from any wall partition or ceiling extending down more than 12 in 305 mm instructions Mounting using exposed installation wiring remove either or both for wire entrance from the plate as required see figure the side of the plate marked SURFACE MOUNTING facing fasten the plate to the surface by installing two 8 wood screws supplied or other suitable fasteners through either the inner or pair of surface mounting holes in the plate the installation wiring either through the center hole in the plate when the wiring is concealed or through the openings the side of the plate when the wiring is exposed Connect the wiring the detector install the detector Align the arrows on the mounting plate and on detector base seat the detector on the plate and turn the detector until it locks in place remove the detector Insert the tip of a screwdriver into the slot in the side of the detector base see applicable illustration for location of slot lift the locking finger of the plate and turn the detector counterclockwise until it can be

exposed wiring This device will not protect life against fire and smoke life safety is a factor the use of smoke detectors is device does not contain a built in signal device will not operate without electrical power This device does contain battery backup It should be electrically supervised with backup at the panel rate of rise feature may be subject to reduced sensitivity over Annual testing of the rate of rise operation is recommended to the latest issue of NFPA 72 or CAN ULC S536 for application inspection and maintenance requirements Refer to the latest of NFPA 72 CAN ULC 524 M86 and Canadian Electrical Code 1 Section 32 for proper installation requirements diagram Detector resistor Refer to the wiring diagrams provided with the control panel for panel connections and end of line resistor value and testing requirements for maintenance and testing of heat detectors are in the latest edition of NFPA 72 Chapter 7 inspections tests maintenance The standard requires that initial installation all restorable heat detectors rate of rise must be tested immediately after installation periodic testing for restorable heat detectors rate of rise two or more detectors on each initiating circuit should be at least yearly Different detectors should be selected for test so that all detectors are tested within five years Sheet Series Heat Detectors 3100341 REV 1.0 2 LAC max
