Specifications as published by Siemens. Please confirm the exact model with us before ordering.
A multi-criteria detector with 4 optical sensors and two heat sensors for rooms with deceptive phenomena, with ASAplus parameter sets; the OOH751-S adds Smoke Entry Supervision.
An FD720 addressable optical smoke detector on C-NET for smoke from flaming and smouldering fires, using forward light scattering.
An FD720 addressable smoke detector with an extra heat sensor for flaming and smouldering fires in rooms with deceptive phenomena.
An FD720 addressable heat detector with selectable fixed temperature and rate of rise parameter sets, for areas where smoke detection is impractical.
An FD720 addressable fixed temperature heat detector for areas with temporary high temperature variations, which signals the panel when its maximum temperature is exceeded.
A detector that analyses smoke, heat and carbon monoxide for very early alarm, made for places such as nursing homes and hospitals where speed of detection is critical.
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.
