1.3 DETECTORS AND OUTPUT MODULES
These devices, installed on the detection lines, are subdivided into two categories:

Detectors (smoke detectors, heat detectors, smoke-heat detectors, manual call points, etc.)

Actuators (actuation modules, etc.)
When the control panel is in “field scanning” mode, the detectors constantly monitor possible alarm conditions (smoke
presence due to fire, temperature increase or air opacity ). If a device detects an alarm condition, it sends the alarm
information to the control panel through the detection line.
The control panel, in turn, activates the outputs associated with the alarm condition and the output modules
associated with the zone which the alarming detector belongs to. As a result, the output modules operate other
devices for managing and/or signalling the alarm condition.
The devices which can be connected to the detection lines of FAP54 control panel are the following:
DEVICE Abbreviation
SMOKE DETECTOR SM
HEAT DETECTOR HT
OUTPUT MODULE OM
CONCENTRATOR MODULE CM
MANUAL CALL POINT MN
CURRENT INPUT MODULE 4-20 mA CI
BEAM DETECTOR BD
SMOKE/HEAT DETECTOR SH
LATCHED INPUT MODULE LI
PULSED INPUT MODULE PI
SMOKE/HEAT/GAS DETECTOR XS
BATHROOM CALL CORD TB
GAS DETECTOR GS
LATCHED INPUT WITH SIREN OUTPUT IS
Each device is characterized by the following basic information:

type of the device

number of the circuit connected to the line where the device is located

address assigned to the device
The maximum number of devices which can be connected to a detection line is 128.
Moreover, FAP54 control panel makes it possible to associate a 32-character text with each device for an easy
identification.
1.4 DETECTION LINES AND CONTROL PANEL
The detection lines are the wired physical connections over which communication between the devices and the
control panel takes place. They are also used by the control panel to power supply the devices.
The number of detection lines which can be connected to the control panel depends on the control panel configuration
and each line can be configured in loop or open mode.
If the line is configured as a loop, the wire where the devices are connected “comes out and returns” to the control
panel, whereas in the case of a line configured as open the wire “comes out” without returning to the control panel.
The control panel is equipped with circuit modules, which provide the interface between the detection lines and the
control panel.
They communicate directly with the devices and notify the control panel about alarms or faults occurring on the field.
Besides, these modules are autonomous and can work also without the control panel supervision.
