INTRODUCTION
Resulted from the latest and most innovative researches, AF921 is a device combining the peculiar features of a
radio control panel with the capacities of a bi-directional telephone dialler with a built-in GSM module. AF921 is
able to control up to 99 detectors that can be identified individually, even through the label function that, if duly
programmed, displays where the alarm comes from (ex: hall, kitchen, corridor, etc..). The telephone dialler can
transmit six vocal and/or SMS messages that can be enabled both from a terminal board control or that can be
combined to a control panel event (alarm, tampering, 24h-channels, low battery, etc..) both on a GSM or a PSTN
(fix net) line. Besides these functions, the telephone dialler can be called remotely and, once it is on line, many
other functions can be enabled. To be more precise, two electric loads by wire and sixteen loads by radio can be
controlled through receivers AF904RR or AF905RR. A hardwired output can also be time-controlled through a built-
in timer to control the load on a time basis. The telephone dialler is provided with an internal GSM module, in this
way it is not connected to any telephone to be housed internally.
TECHNICAL DATA
Power supply 230Vac;
Control panel technical features:
Transmission RF 433MHz, radio range in open space without interferences 100m.
99 radio channels
99 detectors that can be individually identified by a LCD display text label, to be individually
delayed and with AND function;
3 activation zones (A,B,C);
Possibility of storing 32 AF940R remote controls that can be individually identified by a LCD display text label;
Possibility of storing 32 codes from the AF987R keypad and combining them to the three zones (A,B,C),
3 24h-alarm zones: panic alarm, robbery alarm, technical alarm;
6 wired inputs (2 for each zone);
Input for wired key reader;
Memory of latest 200 events;
To be completed with AF912 battery;
Characteristics of telephone dialler:
6 radio-hardwired inputs able to send 6 vocal messages or 6 SMS messages according to the association to
each telephone number;
10 SMS pre-recorded messages for technical alarms;
Possibility of combining transmission of vocal and/or SMS messages to the events of the main section (general
or zone alarms, technical alarm, robbery alarm, low battery, etc..);
Message sending both on PSTN or GSM lines. Possibility of programming alarm message sending on PSTN
line as the priority line. Sending on GSM line in the event of PSTN line failure only, or vice versa;
Load control function. By calling the device from a remote telephone, the following can be controlled:
- an electric load through a relay seated on the device with a potential-free C-NC-NO contact;
- an external relay through an open-collector output;
- 16 AF905RR or AF906RR radio receivers;
- query of the system status;
- switch-on and switch-off of the main section;
Possibility of controlling the relay output also according to programmable times, besides remotely, in order to
control electric loads in timed mode;
On-board GSM module (no additional telephone required).
Standard Compliance
The device complies with the essential requirements and other directions of the 999/5/CE directive.
It also complies with the following directives:
73/23/CEE Low Voltage Directive
89/336/CEE EMC Directive
