This is a photoelectric single station smoke detector designed to give reliable early warning of the presence of smoke where both audible and visual alarms are required. It has a pulsing LED light source and a photodiode sensor in a fully screened sensing chamber. When smoke enters the chamber, the infrared beam is deflected onto the sensor. The LED rate increases to eight times the normal pulse rate. After the photodiode confirms the presence of smoke for two consecutive pulses, it will produce the signal necessary to trip the audible and strobe light alarms. Minimize

Honeywell's 5898 Wireless K-Band DUAL TEC Motion Sensor provides superior detection and reduces the risk of false alarms. The combination of PIR and K-Band microwave technologies enable the sensors to distinguish between real intruders and other environmental conditions by "confirming" each other within a defined area of protection. The sleek, compact design makes it ideal for applications where aesthetics and discretion are critical. PIR sensitivity and temperature sensing can be enabled via local programming or from the central station. Installation is easy, with no jumpers, switches or disassembly, fewer mounting restrictions and an automatic walk test mode that turns on the LED for ten minutes - saving installers one trip up the ladder for each sensor. The 5898 blends perfectly with Honeywell's 5800 Series family of sensors to create a seamless look in any residential or commercial environment. Minimize
