FIK-205-0012-NB Sita ASD detector with sounder & strobe.
Multifunction smoke and heat detector with three smoke detection modes and three heat detection modes. Inbuilt short circuit isolator. These options are set by PC or control panel depending on the system type. Supplied complete with dust cover.
Complete with inbuilt sounder / strobe featuring seven sound patterns and three volume levels and LED strobe array. Inbuilt short circuit isolator.
The Multipoint ASD is a plug-in type smoke detector that utilises a photo-electric sensing chamber to make a measurement corresponding to smoke density. The device also incorporates a thermistor sensing circuit to allow for accurate heat measurement. These elements configure the device to a smoke, heat, or combined setting. Digital communication technology to the control panel ensures accurate data transfer at high transmission speeds.
Install the detector in accordance with the control panel installation manual. The installation must also meet the requirements of any local authority.
Fike recommends spacing detectors in accordance with any local authority. Due to the effects of IR and possible magnetic interference, install detectors no closer than 500mm (preferably 1000mm) to a light fitting or any other source of IR or EMI. Additionally, mount the device with the indication LED facing the light source.
Warning of head contamination is in two stages. Firstly in the form of a ‘Quiescent optical level high or low’ event recorded into the event log and fault or warnings list (depending on the control panel being used), and secondly in the
form of a ‘Smoke sensor failed; signal high event, recorded into the event log and fault list. If the smoke detection mode is set to SM0 (off) the head contamination may still be monitored at the detector depending on the smoke mode, but not by the panel.
Contamination is present then the result will be an LED flash every five seconds at the detector, but the panel will show no fault. If re-programming a device to re-enable smoke detection mode, check the LED status and ensure a clean optical chamber is present first. Failing to do so may cause the device to signal a fire alarm when re-configured.
