Photoelectric smoke detector uses pulsed infrared diodes to eliminate false alarms caused by dust, insects, FR and ambient light. Integrated heat detector triggers alarms at temperatures above 135 F or at temperatures above 105 F with a rise rate of 15 F per minute. Either heat detector or smoke detector can trip and latch LED and alarm relay outputs. UL listed. Powered by either 12 VDC or 24 VDC. For 110 VAC use 24 V wall transformer (DPR- 105-10A-00).
