M050.1.2 - 4 - August 2022
Mounting:
▪Under certain circumstances the amplifier generates a little heat. To ensure reliable operation at
high temperatures, the amplifier should be affixed to a metal base for heat transfer. If this is not
possible, ensure it is mounted with the ventilating fins vertical and sufficient space to allow air
circulation
Order of Connection:
▪The installation must be completed before connecting power to it. Connecting positive to an
amplifier before negative, may damage your amplifier and invalidate the warranty. Electronic
protection devices must not break the negative input to isolate the amplifier
Loudspeaker(s):
▪This amplifier is for use only with the Haztec 8-7050 (4 Ohm) loudspeaker. Connect your
loudspeaker to the “LH speaker” (Left hand) outputs. For dual speaker applications connect the
second loudspeaker to the “RH speaker” (Right hand) outputs. “RRB2” is available only on the RH
speaker
1. For cable runs of less than 2 metres between the siren and the speaker, 18AWG [1.0mm2]
cable is adequate
2. For cable runs of greater than 2 metres between the amplifier and the speaker, and for
volume-critical installations, 15AWG [1.5mm2] cable is recommended
Inputs:
▪The four control inputs are both positive and negative activated. No programming is required to
change between polarities. However, care should be taken to ensure that inputs are left floating
when not activated otherwise the input may appear to be always on, e.g. The indicator in an
illuminated switch may be sufficient to present an input to the amplifier
Horn Input:
▪The horn input is activated by switching to and from positive. It may be used in negative switched
horn circuits
▪For negative switched horn input, it is a requirement to fit an external pull-up resistor (e.g., 1K ohm)
connected to +12VDC
▪Leaving the horn input connected to positive when not in use, will have an increased standby
current of about 5mA
Power wiring:
▪The power supply and ground/chassis cables must be capable of carrying a minimum of 6 A. Take
into account the voltage drop along the length of the supply cables, as this will affect the required
thickness of the cables

CANbus Termination:
▪All CANbus systems must be terminated. Your amplifier is supplied with a plug-in termination
resistor in the CANbus “out” socket. If additional modules such as the 8-82858 switcher are
connected to this socket, fit the termination resistor to the last module in the chain
Auxiliary Microphone:
▪The 8-82002 microphone can be connected directly to the auxiliary input. Volume level is pre-set
but may be adjusted using the Haztec Siren Configuration Utility. Alternatively, if a CANbus control
panel is also in use, this may be used to change the volume level. Press and hold the P.T.T. switch
on the microphone, then use the up / down buttons on the control panel to adjust the volume level
USB:
▪For registration to take place you must disconnect power from the amplifier before connecting to
your PC. Use the Haztec Siren Configuration Utility to make configuration changes. Disconnect
from PC before attempting to operate the siren
Special Tone Facilities:
▪With the use of two loudspeakers this amplifier may also produce;
1. Genuine fanfare, from twin generators pitched a semitone apart
Or
2. Two different tones to sound simultaneously i.e., yelp and any other tone. Also known as
‘mixed’ tone
