Installation
There are no restrictions on unit orientation.
Safe Installation Requirements
To maintain the ingress protection rating and mode of protection, the cable entries must be fitted with suitably rated cable
entry and/or blanking devices during installation. If conduit is used for installation, seal conduit within 18 inches from the
enclosure.
If entries are fitted with adaptors they must be suitably rated for the application. Fitting of blanking elements into adaptors
is not permitted.
Connections are to be made into the terminal blocks using solid or stranded wire, sizes 0.5-2.5mm2 / AWG 20-14. Wire
insulation needs to be stripped 6-7mm. Wires may be fitted securely with crimped ferrules. Terminal screws need to be
tightened down with a tightening torque of 0.4 Nm / 3.5 Lb-in.
Earthing connections should be made to the Internal Earth terminal in the explosionproof chamber or the external earth
stud.
Check that the ‘O’ ring seal is in place before replacing the explosionproof cover.
Selection of Cable, Cable Glands, Blanking Elements & Adapters
When selecting the cable size, consideration must be given to the input current that each unit draws (see Table), the number of
beacons on the line and the length of the cable runs. The cable size selected must have the necessary capacity to provide the input
current to all of the sounders connected to the line.
When selecting the cable size consideration must be given to the voltage drop over the length of the cable run to ensure the min. input
voltage at the point of use (voltage range)
The voltage drop depends on:
- The total current draw if the devices installed on this cable run
- The wire size and total length of the cable run, determining the total resistance of this cable run
- The minimum output voltage supplied by the power supply
The voltage drop and input voltage at the point of use can be calculated.
Total Wire resistance =
Wire resistance / 1000ft x length of cable run x 2

(length of cable run needs to be multiplied by two to account for two wires going to and from the unit)
Total current draw =
Current draw per unit x number of units
Voltage Drop = Total current draw x Total wire resistance
Minimum output of power supply =
Min. voltage at point of use + voltage drop
Flash Rate Settings
The D1xB2XH1 & D1xB2XH2 beacons can produce different flash patterns as shown in Table. The flash patterns are selected by
operation of the flash setting DIP switch on the PCBA
(*setting permitted for use as public mode fire alarm device)
Fig. 8 Dip Switch
1=ON; 0=OFF
Example shown: 10 = Flashing 1.5Hz
(Default setting is 00 1Hz)
Line Monitoring
All DC units have a blocking diode fitted in their supply input lines.
An end of line monitoring diode or an end of line monitoring resistor can be connected across the +ve and –ve terminals
in the flameproof chamber.
If an end of line resistor is used it must have the following values:
Minimum resistance 3K3 Ohms Minimum Power 0.5W
Minimum resistance 500 Ohms Minimum Power 2.0W

for Public Mode Fire alarm Use when used with 1Hz (60FPM),
1.5Hz (90FPM) & 1.33Hz (80FPM) the installation must be
carried out to the correct NFPA standards and guidelines
or CEC regulations.
