Firehawk FH550RF Manual

INTRODUCTION

The FireHawk FH550RF Radio Base is designed to replace the baseplate
supplied with the 250 and 450 ranges of mains powered smoke and heat
alarms. When assembled to a maximum of 15 smoke or heat alarm on any
one system, it allows the installer to power them all from a regularly used
local lighting circuit (BS5839-6:2004 section 15.5) without the need to run a
separate interlinking wire.
The built in 10 year tamper-proof lithium battery will ensure continued
operation in the event of a mains power failure.
The built in multicolour LED provides helpful indication during the simple two
stage set-up procedure and lifetime operation.

INSTALLATION

WARNING: This device and any connected alarms should be installed by
a qualified electrician and in accordance with BS 7671. Do not expose to
dripping or splashing. Install the FH550RF Radio base behind all smoke and
heat alarms in circuit. Ensure all connected circuits are disconnected from the
mains power supply before installation.
DO NOT USE WITH ALARMS BEARING OTHER BRAND-NAMES
OR MADE BY OTHER MANUFACTURERS.
The power supply should be from one of the following two sources (See BS
5839-6:2004) section 15.5:-
a. An independent circuit at the dwellings main distribution board with no
other electrical equipment connected (other than a dedicated supply failure
monitoring device) or:
b. A separately electrically protected and regularly used local lighting circuit.
Only suitably approved cabling should be used. The alarms and FH550RF Radio
Bases should be wired using a minimum of 1mm2 "2 core and earth" cable;
with the Brown to Live (L) and Blue to neutral (N). All alarm circuits should
be protected by a 6amp over-current device. The maximum total length of
wiring should not exceed 250m. Mini-trunking systems can be used via the
removable blank shown in Fig.1 below
WARNING: Ensure the power supplies are turned off before installing this
Radio Base.

FAST-FIX REMINDER FOR FREQUENT USERS ONLY

1. Set rotary switches on all bases to the number of bases in the system
2. Switch on battery, Install bases in position and switch on mains power
3. Press the learning mode button on all alarms within 8 minutes.
4. Ensure the green LED is flashing every 8 seconds.

INSTALLATION OF ALL RADIO BASES
INTO THEIR POSITIONS
1. Ensure that the mains supply is switched off.
2. IMPORTANT: Ensure that the rotary selector switch (see Fig 2) is set to
the number that equals the amount of radio bases in the complete system;
ie if you have 2 alarms in the complete system then the rotary selector
switch on all alarms should be set to 2.
FIG. 2
3. DO NOT SET ANY ROTARY SELECTOR SWITCH TO 0: SEE
"IMPORTANT INFORMATION" BELOW.
4. Switch the Battery Switch to the "on" position. (See Fig 3) The LED will
start to flash Green.

Battery Switch
5. Connect the power supply wires to the connection terminals on the RF-
Base. (See Fig 1) Make sure that the wires are connected correctly; ie Live
to L, Neutral to N and the interlink wire (if used) to I.
6. Repeat the above process for all Radio Bases you intend to use.
7. WARNING. Re-chargeable batteries may be depleted. Do not leave on
battery only for more than a few minutes.
If the rotary selector switch of all units is in position 2 to F then all units must
take part in a learning process before the system becomes operational. After
a successful learning process the group of units can be considered a "family
of friends". Only members of the family are able to communicate with each
other, i.e these family units do not respond to any units in "0" position or
other radio base systems in adjacent properties. A maximum of 15 units can
be fitted to this family.

IMPORTANT INFORMATION:

1. If the rotary selector switch is in position 0 (factory default) then all units
will communicate without restrictions and learning mode is switched off.
2. This means that these units will link with any other units whose position is
set at 0 or any other position (2-9 or A-F) that are within range.
3. This could lead to "false" alarms caused by alarms in adjacent properties.
4. IT IS STRONGLY RECOMMENDED THAT YOU DO NOT LEAVE
ANY RADIO BASE IN THE 0 FACTORY DEFAULT SETTING.

2. THE LEARNING PROCESS

1. Ensure you have set the rotary
selector switch on all radio bases to
LED
the same number that should equal
the number of bases in the system.
For example, if you have 2 bases in
the system, the number 2 should
be selected on ALL radio bases. If
you have 11 in the system then
the letter B should be selected. See
Table 1.
2. Switch on the mains power supply

learning process. A flashing Red LED
o the side of the base indicates that
a given unit is in "learning mode".
4. Repeat this learning process for
each unit in the system within 8
minutes.

5. Check that the Green LED is flashing every 8 seconds on all installed bases;
this indicates that the system is operating normally, and that all units are
linked.
6. FireHawk alarms from the 250 or 450 range can now be installed directly
onto the Radio Base using the instructions supplied with them. Please
discard the mounting plate supplied with the alarm. Test all alarms using
the test button. Repeat this learning process for each unit in the system
within 8 minutes.
1 The alarm beeps every 64 secs – Check the 3 x AAA batteries have been
2 The radio base beeps every 64 secs – Check that 230v supply is connected
3 The Red LED is flashing every 8 seconds (and the rotary selector switch is in
To correct this, check that the rotary selector switches of all units have
the same setting and re-start the learning process by pressing the small
installation push button for ½ a second on all units, as per Step 2. If this
still do not solve the problem, try to troubleshoot and solve the problem by
excluding one unit at a time from the family of units by disconnecting the
mains supply and turning off the battery. When doing this, do not forget to
change (decrease) the number on the rotary selector switch on each unit,
before re-starting the learning process as per Step 2.

position 2 to F See table 1). This indicates that either:-
a) no learning process has taken place, or
b) the last learning process failed due to timeout (more than 8 minutes ), or
c) there was an error on one or more of the rotary selector switch settings.
NOTE: As per IMPORTANT INFORMATION above, if the rotary selector
switch is in position 0 on any unit, then that unit will hear any other unit
anywhere within range, regardless of their code settings.
If another unit with different number selected on the rotary selector
switch code selector is located during the learning process, the unit is
"locked" and the Red LED lights together with beep sound. (As per table 2
above) This will continue until:
1. the installation button is pushed, or
2. the mains supply is switched off, or
3. until one hour has elapsed
If there is a power supply failure during the learning process, you need to
start from the beginning of Step 2
