Purpose
The SITE ALERT RF is designed to alert the occupants of a building or site in the event of an emergency
such as a fire. The SITE ALERT RF is a self-contained, battery operated alarm unit which can be linked
wirelessly with up to 30 other units, so that the operation of one unit will cause all other linked units to
sound. The SITE ALERT RF is specifically designed for use on construction sites and other temporary
situations, where a conventional fire alarm system is not appropriate.
Instructions for Use
Each SITE ALERT RF system must have a Master Unit (SA02M). Up to 30 Subsidiary Units (SA02S) or
Detectors (SA02HD or SA02SD) can be connected to the Master unit to create a system of
interconnected units.
Before installation:
1) Decide how many Site Alerts will be linked together on the system
2) Remove screw from the front of each Subsidiary Unit.
3) Open the cover and set the address for each Subsidiary unit using the DIP switches (see DIP
switch address diagram)
4) Connect the 2 sets of batteries. The red LED in the switch will pulse regularly, indicating that the
Subsidiary unit is not yet connected to the Master unit.
5) Once all Subsidiary units have been addressed and have the batteries connected, open the
Master unit and set the Master unit address on the DIP switches the same as the last Subsidiary
unit (i. e. highest numbered address). Insert the batteries. To access the D cell battery holders,
two screws holding the white plastic section must be removed and the white section will slide
out towards you. Take care when re-securing the white plastic section, to avoid trapping the
wires. The white plastic section should be secure, but do not overtighten the screws. Connect
the 2 sets of batteries in the Master unit.
6) The red LEDs on the switches on each Subsidiary unit will stop pulsing once they have established
contact with the Master unit.
Heat Detectors
Detectors are set-up and addressed in the same manner as a Subsidiary Unit. To access the DIP switches
and batteries, remove the detector head by twisting anti-clockwise, and then remove the Pozi screw
behind the detector. 3 x C-cell batteries should be fitted in the designated battery holder, and 1 x 9V
(PP3) battery should be fitted in the rear of the white detector. (see page 6). Once the batteries are
connected the LED on the outer casing will pulse until the Detector is connected to the Master unit.

Since heat rises to the highest point first, the detector should be securely mounted horizontally, as close
as possible to the ceiling. Avoid mounting the detectors within 500mm of a wall, light fitting or other
obstruction (e.g. beam). (Further information regarding the siting of detectors, which may be helpful, is
available in BS5839-1)
The 9 volt battery in the detector head is located under the battery pocket door –the head will need to
be removed by twisting it anticlockwise. The detector should be tested on a weekly basis, by pressing
and holding the test button.
The detector should be kept clean, and any dust removed on a regular basis to ensure that its sensitivity
is not reduced. The detector should never be painted.
The detector is powered by a single alkaline 9V PP3 battery, readily available. The detector will emit an
intermittent ‘beep’ when the battery requires replacement.
Mounting the Site Alerts
The Site Alerts can now be mounted in the desired locations. The Master unit should be mounted in a
central location, within range of all the Subsidiary units. There are fixing holes in the backplate of each
unit. Each unit should be securely mounted to prevent damage by dropping or falling, and it should be
mounted as high as is reasonably practicable (recommended: 1.5m). The cover can then be replaced
using the fixing screw.
In general the Site Alerts should be sited on exit routes in easily accessible places, which are unlikely to
be obstructed. Units should be sited so that it is possible to reach a Site Alert from any point in the
building within 45m. The stairwells are ideal locations. This ensures that Howlers are in easy reach of
personnel and that the sound levels are adequate to warn all persons present. Wherever possible, Site
Alerts should be mounted on mobile fire points or backboards so that they can be repositioned easily
and quickly.
If the red LED in the switch of any Subsidiary unit starts to pulse during the installation process, this
indicates that it has lost contact with the Master unit, and a better location should be found. On large
projects, some patience may be required to ensure that the best location for each unit is found.
Once all units have been mounted, and no LED switches remain flashing, the system is now ready for
use.

Testing:
The SITE ALERT RF system should be tested after installation and weekly thereafter to ensure correct
operation. Push and hold the switch on any unit until the alarms sound. Reset the system by pushing
the switch on any unit three times in succession. The sirens will continue to sound for a brief period then
will silence.
The SITE ALERT RF monitors the connections between units continually. If any Subsidiary unit becomes
disconnected from the Master unit, the red LED in the switch of the Subsidiary unit will pulse regularly.
This unit should be re-positioned to a location where connection can be re-established. Please note that
in buildings where the layout is changing frequently, disconnections will occur, and the user should be
aware of this.
If it seems difficult to regain connection, taking the Subsidiary Unit to the Master Unit, and powering
down both units (disconnecting the batteries) and powering them up again will restore the connection.
Batteries:
The SITE ALERT RF units are powered by standard alkaline batteries. These should be replaced at least
annually. Disconnect the old batteries and dispose of them safely. Position the new batteries in the
same manner and re-connect. If the SITE ALERT RF is in storage for any length of time, disconnect the
batteries.
The SITE ALERT RF has an automatic battery test facility. If the 9V (PP3) battery requires replacement
two LEDs on the beacon will illuminate. If the 1.5V batteries require replacement the LED in the switch
will flash intermittently (...-…-...-…-...- etc.). The Master unit contains 8 x ‘D’cell batteries, and the
Subsidiary units contain 3 x ‘C’cell batteries. The LED in the switch in the Master unit will pulse regularly
if any Subsidiary unit becomes disconnected. Likewise, the LED in the switch in the Master unit will flash
intermittently (...-…-...-…-...- etc.) if the 3V batteries in any of the Subsidiary units is low.
NB: Low batteries can cause disconnections, so always check the batteries if disconnections are
occurring between the Master and Subsidiary units.
Spare parts:
Batteries are available from your SITE ALERT RF supplier. Use only high quality alkaline batteries
(Duracell Procell, Energizer, or equivalent)
Running more than 30 units
If more than 30 Subsidiary units are required to operate in close proximity, it is possible to operate up
to 7 other systems on different channels. In order to set up a system on a different channel, DIP switches
are used to re-code the system. See the DIP switch channel address diagram for further information.
Units on different channels do not link together.

Trouble Shooting
1) Site Alert Subsidiary not sounding when system activated
2) Site Alert Subsidiary Switch LED is flashing
Is the LED in the switch pulsing
regularly?
It is likely that there is a
problem with the location of
the Site Alert. Try
repositioning the Site Alert
nearer the Master unit. Does
the LED stop pulsing?
Problem solved. Test the Site
Alert by pressing the switch
until the sirens sound.
No
Take the Site Alert back to the
Master unit. Press the switch
3 times in succession. Does the
LED stop pulsing?
The 'C' cell batteries are
exhausted. Open the Site Alert
replace the 3 'C' cell batteries.
Test the Site Alert for correct
operation.
Now take the Site Alert back to
the desired location, ensuring
that the LED does not start to
pulse. Test the Site Alert by
pressing the switch until the
sirens sound.
Open the Site Alert and
disconnect the 'C' cell
batteries. Reconnect, and the
LED should stop pulsing.
Now take the Site Alert back to
the desired location, ensuring
that the LED does not start to
pulse. Test the Site Alert by
pressing the switch until the
sirens sound.
Is the LED pulsing regularly and
constantly?
The Site Alert is disconnected
from the Master. Press the
switch 3 times.
If the LED continues to pulse,
move the Site Alert to a new
location, nearer the Master
where the pulsing stops. Test
the unit.
No
Test the Site Alert for correct
operation.
Open the Site Alert, remove the
3 'C' cell batteries and replace
with new
If the pulsing is intermitent (...-
...-...-...-etc) the 'C' cell batteries
need to be replaced.
