GENERAL DESCRIPTION

The S900RL and S900RLFIRE SpectrAlert strobes by Syste

m

Sensor are a series of visual signaling devices for use on fir

e

alarm applications. The S900RLFIRE strobe has the word ‘FIRE

’

printed in 25mm height lettering on the cover, whereas th

e

S900RL has a plain cover. These strobes are designed to be use

d

on 24 Volt DC systems and have low operating current. Whe

n

these strobes operate on the rated supply voltage, they will flas

h

once per second until the power supply is switched off.
Note: They are not compatible for use with MDL or MDL

3

synchronization modules or coded power supplies.

STROBE OPERATING CONSIDERATIONS:

Generally, for purposes of determining the wire size necessary
for the system, it is best to consider all of the devices as
“lumped”on the end of the supply circuit

(simulates “worst case”).

Typical wire size resistance:

18AWG Solid:
16AWG Solid:
14AWG Solid:
12AWG Solid:

Example: Assure you have 10 devices on a zone and each
require 50mA average and 2,000m of 14 AWG wire (total
length= outgoing + return).

The voltage at the end of the loop is

0.050amps per device x 10 devices x 10ohms/1,000m x 2,000m
=10 volts drop.

The same number of devices using 12

A

WG wire produce only 7
volts drop. The same devi ces u sin g 18 AW G wire will p rod uce
27 volts. Consult your panel manufacturer’s specifications, as
well as SpectrAlert’s operating voltage range to determine
acceptable voltage drop.

CONSIDERATIONS

Power System supply DC filtered voltage. The system design
engineer must calculate the

num

ber of units used in a zone
based on the type of power supply.
Be certain the sum of all the device currents do not exceed the
current capability of the supply in order to assure the product
can work normally.

WIRE SIZE

The designer must be sure that the l ast device on the circuit has
sufficient voltage to operate the device within its rated voltage.
When calculating the voltage available to the last device. It is
necessary to consider the voltage drop due to the resistance
of the wire. The thicker the wire, the less the voltages drop.

REMOVAL OF THE UNI

T

FROM MOUNTING PLATES

To remove units from mounting plates, insert Quick Click Removal Tool as shown to unlock snap. While pushing in Removal Tool to
release the snap, pull back on the strobe. Hinge the horn/strobe module, disengage the locking Rib, and lift the horn/strobe away from
the mounting plate.

THE

LIMITATIONS O

F

The signal strobe may cause seizures. Individuals who have positive photic
response to visual stimuli with seizures, such as persons with epilepsy, should avoid
prolonged exposure to environments in which strobe signals, including this strobe, are
activated.
The signal strobe cannot operate from coded power supplies. The strobe must
have an uninterrupted source of power in order to operate correctly. Xi'an System
Sensor Electronics Ltd. recommends that the horn and signal strobe always be used
in combination so that the risks from any of the above limitations are minimized.

The strobe will not work without power. If power is cut off for any reason, the
strobe will not provide the desired visual warning signal.
The signal strobe may not be seen. The electronic visual warning signal uses
some high light LED indicators. It flashes at least once every second. The strobe
must not be installed in direct sunlight or areas of high light intensity (over 60
foot candles) where the visual flash might be disregarded or not seen. The strobe
may not be seen by the visually impaired.
