To perform the anti-removal protection, it is necessary to keep closed the anti-removal
contact seated on the rear side of the sounder by fixing a screw in the wall (in the
position shown by the drilling jig) and leaving it project by 8 mm that will press
the pin (brass coloured) and therefore close the contact as shown in the figure
Note: A series of beeps produced for 30 seconds when activating and disactivating
indicate that the battery needs to be replaced.
AF53901R Outdoor self-powered wireless second generation sounder
The new generation sounder differs from the above-described sounder for the following features:
The anti-removal contact is kept pressed by a projecting cursor that moves automatically back upon fixing
•
the device to the wall. Therefore, the above-described screw is not required.
Polycarbonate auxiliary antifoaming cap for horn protection
•
Current demand when quiescent: 170 µA max @ 7.2 V
•
Current demand under alarm: 1.3A max @ 7.2 V
•
Acoustic radiation pressure at 1 metre: 116 dB
•
Lamp blinker
•
AF53901R-DB DUAL BAND SELF-POWERED WIRELESS SOUNDER
The AF53901R-DB siren has the following technical characteristics:
Power: supplied by 7.2V-13Ah lithium battery (code AF915) or by alkaline batteries
•
Absorption: stand-by status170uA – in alarm status1.3 A
•
Acoustic signaller: 116 db at 1meter, controlled by the control unit and timed at 3 minutes for every alarm
•
cycle
Contemporaneous optical alarm with a 6V-0.25A flashing lamp – approximately 40 flashing per minute
•
Alarm delay (pre-alarm): 12 seconds with acoustic signals (series of beeps)
•
Anti-attack pre-alarm signaller: acoustic signals (beeps) and flashing for 3 minutes in case of alarm. This
•
function works only with AF922RF, AF923RS and AF921 control unit.
Confirming signaller: 3 beeps and flashing for system ON, 1 beep and flashing for system OFF
•
Prolonged acoustic signaller when the siren is not working for maintenance (control unit under test): the
•
opening doesn't cause an alarm.
Completed programming signaller: sequence of 6 beeps with flashing.
•
Flat battery signaller: repeated beeps when the system is activated and deactivated.
•
Radio range: 100 meters on free air. It can suffer reductions in inner space, due to devices position, room
•
structure or noise on the band. It is necessary to verify that the radio range is enough always before
installing the alarm.
Dual band transmission of operating system every 26 minutes (supervision), with flat battery signaller
•
Tamper alarm transmission in case of opening, detaching from the wall or forcing. You can enable this
•
function with the "shock" jumper included on the board
Operating weather condition: -20°C/+60°C
•
To program the device, proceed as follows:
Open the siren and set the "shock" jumper on the required function, then fix it on the wall.
•
Transmitting area programming (tamper - supervision): set the control panel in order to receive the siren
