MKT. #8830018 - REV C06/13PRINTED IN USAPAGE 1 OF 2RHARATE OF RISE/FIXED TEMPERATURE HEAT DETECTOR Potter Electric Signal Company, LLC St. Louis, MO Cust Service: 866-240-1870 Tech Support: 866-956-1211 Canada: 888-882-1833 combination Rate of Rise/Fixed Temperature Heat Sensor (RHA) is a listed Analog/Addressable combination temperature heat sensor compatible with any fire alarm control panel that has the Potter/Nohmi protocol. The heat sensing portion utilizes a proven thermistor for accurate and reliable heat detection. The sensor and base (not included) are made of a durable plastic in an eggshell white (off white) to blend in with the ceiling. The RHA is UL and cUL listed with a selectable fixed temperature point from 135 to 174 and a rate of rise feature. The rate-of-rise operates when the temperature increases 12-15 F occurs. The heat sensor is ideal for installations needing the earlier heat detection. The RHA has two LEDs that allow for 360 viewing. The sensor is compatible with any of the Potter/Nohmi bases and simply twists on. The RHA is addressed using the hand held programmer or the control panel addressing function. SpacingThe RHA spacing is dependent on the alarm set-point. The unit is listed from 135 F to 174 F.

The unit communicates with the control panel as it is polled. The LEDs flash every time the unit is polled and they will latch steady if the unit is in an active status. The RHA is a single sensor that may be used in a wide variety of applications for property protection. The RHA has a the rate of rise heat detection to provide detection of an escalating fire. The unit has a sleek design and low profile for pleasing aesthetics. The temperature sensor is protected within the mold of the unit to prevent accidental damage. Compatible BasesAll bases will mount on a single gang, double gang, octagon, 4 square or mud ring electrical Standard BaseAB-66 Standard BaseAIB6 base with an isolator module included.
