Multi-sensors help reduce false alarms

Nittan (UK) Ltd., a leading UK manufacturer of conventional and addressable fire detection products, has launched two new Evolution multi sensors, designed using Nittan’s award winning Dual Optical Technology to reduce false alarms.

Multi-sensors help reduce false alarms

Whilst both units feature Dual Optical sensing, the EV-DPH-A1R also incorporates an A1R (54ºC) heat detector and the EV-DPH-CS a CS (90 ºC) heat detector. As such, the units are capable of monitoring two very different by-products of a fire -smoke and heat - so response to all fire types is significantly improved when compared with single sensor type units.

The EV-DPH-A1R and EV-DPH-CS work on an FSK signalling protocol for robust, reliable communications and are EEPROM Addressed (Programmer). They feature RIL and base control outputs and come with a 360º OMNIVIEW™ LED indicator, permitting clear and visible indication of the sensor's operation from any angle.

Both sensors offer advantages in areas where risks are undetermined or variable, or where false alarms may be a particular problem, as well as areas where the highest level of protection is desirable. The EV-DPH-CS is particularly suited to areas with a high ambient temperature.
Approved to EN54-5:2000 + A1:2002 and EN54-7:200 + A1:2002 + A2:2006, the EV-DPH- A1R and EV-DPH-CS multi sensors are the latest additions to Nittan’s Evolution range of Analogue Addressable products.
