IV. WIRING
Wiring for synchronized strobes and horn.
Using this method you may:
Use only two wires to synchronize the temporal horn and strobe with the ability to mute the horn (place
switches
1
and
2
in the ON position on the HEC24, HEC3-24, HEC3-12, WHEC24).
Mute the horn
only
when the temporal horn option has been selected.
Use the Hochiki America synchronization protocol to provide synchronize and mute the horn.
Wiring for synchronized parallel (unison) horn/strobe operation.
Using this method you may:
Use four wires where two wires are used to power and synchronize the strobe and two additional wires are used
to power and synchronize the horn (place switches
1
and
2
in the OFF position on the HEC24, HEC3-24,
HEC3-12, WHEC24).
Choose either continuous horn and allow the FACP to control the horn or choose temporal horn and synchronize the horns with the Hochiki America synchronization protocol.
Use the Hochiki America synchronization protocol to provide synchronization and mute the horn.
NOTICE
:
FOR THIS OPTION, SWITCHES 1 AND 2 ON THE HEC24, HEC3-24, HEC3-12, WHEC24 MUST BE IN THE OFF POSITION TO ISOLATE POWER TO THE AUDIBLE AND VISIBLE
PORTION OF THE CIRCUIT.
ALL STROBES ARE DESIGNED TO FLASH AS SPECIFIED WITH CONTINUOUS APPLIED VOLTAGE. THIS APPLIANCE IS NOT RECOMMENDED FOR USE ON CODED OR PULSING
SIGNALING CIRCUITS. HOWEVER, USE OF THE HAVSM CONTROL MODULE IS PERMITTED TO SYNCHRONIZE THE STROBE AND/OR MUTE THE HORN.
REFERENCE HAVSM CONTROL MODULE MANUAL (550-0539, DATED 03/04/11) FOR SYNCHRONIZATION MODULE WIRING DIAGRAMS. HAVSM MANUAL CAN BE OBTAINED AT
HTTP://WWW.HOCHIKI.COM OR CALL HOCHIKI AMERICA CORPORATION AT 714-522-2246.
Conventional Method:
You may connect both the strobe and the horn directly from a source of rated power without the use of a control module. However, the horns and strobe lights will NOT be synchronized. Place
switches
1
and
2
in the ON position on the HEC24, HEC3-24, HEC3-12, WHEC24 to power both the audible and visible from a single pair of power wires. If you wish to power the horn and
strobe from independent sources of power, place switches
1
and
2
in the OFF position on the HEC24, HEC3-24, HEC3-12, WHEC24 and connect power to the appropriate terminals.
CAUTION:
When using only a single power source to
energize the strobe and horn (switches 1 and 2 in the
ON position), the in/out wiring must be under the S+ and
S- terminals only. Failure to do so may result in damage
to your signal. For the horn only (HEH24 and HEH12)
and strobe only (HES24, HES3-24, HES3-12, WHES24),
only the top three terminals are to be used.

CAUTION:
A jumper card is provided to test for correct wiring
in the supervisory mode only. DO NOT pass alarm
current through the jumper.
Mounting Bracket:
Allows the installer to pre-wire the system, test
for system supervision, remove the signal head
until occupancy, switch out Hochiki America
signals without changing mounting brackets and
has locking edge connector for snap-in-place
installation.
Instant Voltage Verification:
It is often necessary to confirm the voltage drop
along a line of devices. The access holes are
provided in the back of the terminal block to
allow the voltage to be measured directly
without removing the device. Typically this
would be done at the end of the line to confirm
design criteria. Most measurements will be
taken using the S+ and S- locations although
access is provided to other locations.
NOTICE:
CARE SHOULD BE TAKEN TO NOT
SHORT THE TEST PROBES.
