Greystone CMD5b1000-010 Carbon Monoxide Detector uses an electrochemical sensor to monitor the carbon monoxide level and outputs a 4-20 mA signal. Optional Modbus communications output is available. The standard product features a 2-wire loop-powered output. Optionally, the device may be configured with an alarm relay and operates in 3-wire sourcing mode.

OMEX 205 DC Wireless Long Life Smoke Alarm For Residential Applications provides battery-powered smoke detection and alarm functions within a single unit. Interconnectable 205 DC smoke alarms use a wireless transmission path. Configuration into a closed group ensures that other units within the radio signal range are not affected by a test or fire alarm occurring within the configured group. Advanced electronics in conjunction with a photoelectric smoke sensing chamber provide early detection of fire and high immunity against unwanted alarms.

GST DI-9102E Intelligent Photoelectric Smoke Detector is a new generation product, connected with an intelligent fire alarm control panel to form a fire alarm system.  The detector is developed from the sensing chamber by scattering theory.

Tyco 711P Optical Smoke Detector is for use in conventional two-wire detection systems, where detectors are normally connected in zones. Tyco 711P 516.900.101 is a microprocessor-based, conventional optical detector offering features designed to extend the shelf-life of the detector and reduce installed costs to customers. This device is EN54, MED and IACS approved, making it suitable for land applications as well as Marine.

Jabo JBS02 Stand Alone Smoke Detector with 9V Battery, Photoelectric sensing technology. Battery case at the back of a sensor for easy removal of a battery.  The alarm is designed to detect smoke. It cannot prevent a fire.

Vesda VSP-962- Vesda E Filter Cartridge uses a two-stage filter to protect the optics of the detection head.  This filter is intended for single use.

V-Great VG-6623 Conventional Optical Smoke Detector (hereinafter referred to as Detector) is a product developed with integrated MCU and a reliable fixed fire judgment program that makes it work stably and reliably. The detector is developed base on the infrared scattering principle and high-performance optical sensing chamber.

System Sensor 22051E photoelectric smoke detector has a completely new detection chamber design by System Sensor. This delivers improved responsiveness, reduced sensitivity changes caused by settling dust and reduced false alarms resulting from insect ingress and other debris.
