Specifications as published by System Sensor. Please confirm the exact model with us before ordering.
A white addressable photoelectric smoke detector working on the light scattering principle, with smoothing filters and embedded software to resist unwanted alarms. The 22051EI version has a built-in isolator.
A three sensor photo-thermal-infrared (PTIR) detector that System Sensor presents as the environmentally friendly alternative to ionisation detectors, with a comparable response to fast flaming fires and fewer false alarms.
Analogue addressable heat detectors using a low mass thermistor and microprocessor for fast response, covering 58°C and 78°C fixed temperature and rate of rise. Any model can be configured in software to the mode needed.
A high sensitivity addressable smoke sensor with a high power IR LED and a high gain receiver amplifier, which System Sensor rates 100 times more sensitive than standard smoke sensors.
A multi-criteria detector that combines carbon monoxide, photoelectric smoke, heat and infrared sensing in one device. It normally runs at high immunity and becomes very sensitive when fire characteristics are sensed.
A plug-in intrinsically safe photoelectric smoke sensor with analogue addressable communications, engineered so it cannot become a source of ignition in potentially explosive atmospheres.
A battery operated, Wi-Fi enabled photoelectric smoke detector from the IMPACT by Honeywell range. When smoke reaches its alarm threshold it sounds a buzzer, flashes an LED and sends real-time alerts to a smartphone through the IMPACT by Honeywell app.
A battery operated standalone smoke alarm with photoelectric sensing that sounds an alarm and lights a red LED when smoke reaches its threshold. It runs on two AA batteries and also warns of a low battery or a chamber fault.
An intelligent addressable photoelectric smoke detector with an optical chamber that senses smoke from a wide range of fires, and sensitivity that is programmable and monitored by the panel.
An intelligent photoelectric smoke detector with dual thermistors that add 135°F (57°C) fixed temperature heat sensing in the same head.
An S200A plug-in photoelectric smoke detector listed with the DXc and ZXSe panels. Its detection chamber is designed to cut false alarms from dust, insects and other debris.
An S200A multi-criteria detector that adds 58°C fixed temperature and rate of rise thermal sensing to a photoelectric smoke sensor, for better false alarm immunity and faster response to a wide range of fires.
