Fire detectors / annunciators

ARF-WL8-OV
Wireless optical smoke detector with built-in voice annunciator

The wireless optical smoke detector with built-in voice annunciator samples the air in the protected area to provide the earliest warning of fire and yet offers a high level of false alarm rejection. The detectors provide sound and strobe light path to the nearest safe exit in case of a fire.

FEATURES: 
Wireless evacuation control system 
Adjustable sensitivity – low, normal or high 
Bi-directional wireless communication 
Fully intelligent 
Voice synchronization with other annunciators 
10 years of battery life 
Self-optimizing wireless frequency and amplitude algorithms 
Patented design of smoke inlet to optical chamber 
Operating temperature range: –10 °C to +55 °C

ARF-WL8-OVR*
Wireless optical smoke detector with built-in voice annunciator and red visual alarm device

The wireless 3-in-1 optical smoke sensor with an integrated voice annunciator and red visual alarm device (VAD). The device analyses the protected area for traces of smoke. An alarm condition is generated when the smoke level exceeds the threshold. The alarm signal is relayed to the Control Panel via the connected translator / expander modules. The advanced design of the optical chamber guarantees a very high level of dust protection, effectively increasing the time between maintenance procedures.

FEATURES: 
Bi-directional wireless communication
Intelligent algorithms
Tamper switch
10-year battery life
Self-optimizing wireless frequency and amplitude algorithms
Patented smoke chamber design
Integral VAD with red LED’s
Sounder

* - Not certified to EN54

ARF-WL8-OS
Wireless optical smoke detector with built-in sounder

The wireless optical smoke detector with built-in sounder samples the air in the protected area to provide the earliest warning of fire and yet offers a high level of false alarm rejection. Build-in sounder provides notification in case of a fire.

FEATURES: 
Adjustable sensitivity – low, normal or high 
Bi-directional wireless communication 
Fully intelligent 
Sound synchronization with other sounders 
10 years of battery life 
Self-optimizing wireless frequency and amplitude algorithms 
Patented design of smoke inlet to optical chamber 
Operating temperature range: –10 °C to +55 °C

ARF-WL8-HS
Wireless heat detector with built-in sounder

The wireless heat detector with built-in sounder continuously samples the temperature in the protected area to provide the earliest warning of fire. The device is capable of being configured on site as either a fixed temperature or rate of rise. Build-in sounder provides notification in case of a fire.

FEATURES: 
Rate of rise or fixed temperature mode 
Bi-directional wireless communication 
Fully intelligent 
Sound synchronization with other sounders 
10 years of battery life 
Self-optimizing wireless frequency and amplitude algorithms 
Operating temperature range: –10 °C to +55 °C
