AF913R & AF913DB multifunction perimeter detectors
The AF913R & AF913R-DB detectors shown in the picture, has the following technical characteristics:
Power: alkaline battery 9 V
standard size 6LR16
Consumption: 8µA during stand-by
20 mA during transmission
Life: 18 months with an alkaline battery
Operational functions
:
- signal of open door
-
signal of closed door
-
shock alarm (attempted intrusion)
-
alarm by pulse-counter (by external connection of inertial detectors)
-
technical alarm (by external connection of technical detectors)
Transmission of the presence signal (supervision) and battery low level every 25 minutes
R.F. features: Quartz A.F. transmission at 433,92 MHz, max. power 10mW
Signal coding: 36 bit random code, previously programmed. Over 60 billion combinations
Working range: over 40 m in open space, 30 m approx. in residential environment
Dimensions: 135x32x27 mm
The AF913R detector can carry out various operational functions that can be selected by means of special
dipswitches. As shown in Figure
, it is provided with a REED contact operated by an external magnet supplied
with the device which must be installed to protect all doors and windows. In this case, the magnet must be installed
on the door or window to be protected while the detector must be installed on the frame.
When the door is closed, as shown in the figure, the distance between the detector and the magnet must
not exceed 5 mm.
By increasing the distance between the magnet and the detector, the REED relay opens its contact and
produces the alarm that will be transmitted to the control panel.
By reducing the distance between the magnet and the detector, the signal of end of alarm which interrupts
the alarm will be transmitted to the control panel provided that micro-switch 3 is in ON position.
An internal anti-shock device is provided: it consists of a piezoelectric device that, in the case of a violent
shock, produces an alarm that is transmitted to the control panel. This function can be cancelled by means of
micro-switch 4. By the AF913R detector, the state of an externally connected NO or NC contact can be transmitted
to the control panel. Therefore as shown in the figure, if the output contact of a detector of any kind (temperature
detector, water detector, inertial detector for roller shutters, etc.) is properly connected, the control panel can
receive the corresponding alarm signal. By dipswitches 1 and 2 (pulse count) the number of local alarms can be
calculated (only for the N.C. input) and then transmitted to the control panel.
