I. INTRODUCTION

The Hochiki America models HEC24, HES24, HEH24, HEH12, HEC3-24, HES3-24, HEC3-12, HES3-12, WHEC24, WHES24 are high quality audible and/or visible signaling appliances. The
high intensity strobe utilizes a Xenon flash tube that generates a high-intensity flash visible from all angles. This appliance is intended to provide a visible, audible or audible/visible, depending
on the model, notification signal for the purpose of life safety and property protection. The HEC3-24, HES3-24, HEC3-12, HES3-12 are provided with a slider switch which allows for candela
selection at the installation site; the candela intensities which can be selected are 15Cd, 30Cd, 60Cd, 75Cd, or 110Cd (24VDC only). The HEC24 and HES24 are fixed candela units; the
candela intensities which can be ordered, are 177Cd and 15/75Cd. The WHEC24 and WHES24 are fixed candela units, available in a 75 candela intensity only. This appliance is ideal for any
occupancy that requires notification appliances per the applicable building or fire code or wherever dependable alarms are required.

The HEC24, HES24, HEC3-24, HES3-24, HEC3-12, HES3-12 strobe is listed in compliance with ANSI/UL 1971, Signaling Appliances for the Hearing Impaired (The 15/75Cd model on the
HEC24 and HES24 is additionally listed in compliance with ANSI/UL1638). The WHEC24 and WHES24 strobe is listed in compliance with ANSI/UL 1638, Visual Signaling Appliances - Private
Mode Emergency and General Signaling.

II. LOCATION

This appliance is intended for use in Fire Alarm Systems and is to be installed in accordance with this manual, the recommendation of the local authorities having jurisdiction, and other NFPA
documents that provide standards on notification appliances for protective signaling systems. The HEC24, HES24, HEH24, HEH12, HEC3-24, HES3-24, HEC3-12, HES3-12 are intended for
indoor installations only; this appliance is not listed for outdoor or drip proof applications. The WHEC24 and WHES24 are intended for indoor or outdoor installations; this appliance is rated for
outdoor or drip proof applications when used in conjunction with the HGOE Enclosure.

Wall mounted strobe and horn/strobe appliances shall have their entire lens at heights above the finished floor of not less than 80 in. (2m) and not greater than 96 in. (2.4m)**. Spacing shall be
in accordance with Table A. If a room configuration is not square, the room size that will entirely encompass the room or subdivide the room into multiple squares shall be used. Wall mounted
horn only appliances shall have their tops above the finished floors at heights of not less than 90 in. (2.30m) and below the finished ceilings at heights of not less than 6 in. (152mm). Different
mounting heights shall be permitted by the AHJ provided the sound pressure level requirements of NFPA 72 are met.

III. MOUNTING, ROUGH-IN BOX AND RUN WIRING

This unit is designed for mounting to most single gang boxes, 4" square outlet boxes, 2-gang masonry boxes or non-metallic 2-gang switch boxes. Conduit entrance to boxes should be
selected to insure sufficient wiring clearance.

1. Run a minimum 18 gauge insulated 2 or more conductor cable.

2. Mount a box for each remote signaling appliance. Screw bracket onto box. Insert signal into bracket and slide to the right firmly into the terminal block receptacle. Place housing over
mounted assembly and screw together with single screw at the bottom of the signal. Cover screw with plastic tab.

NOTICE: WIRING SHOULD BE CONNECTED TO MOUNTING BRACKET PRIOR TO MOUNTING SIGNAL. INCOMING POSITIVE POWER LEAD MUST BE BROKEN AND EACH LEAD IS
TO BE INSERTED INTO EACH OF THE TOP TWO TERMINALS. IF TWO POWER RUNS ARE MADE TO THE SIGNAL, ONE FOR THE STROBE AND ONE FOR THE HORN, ONLY ONE OF
THE RUNS MUST HAVE ITS POSITIVE LEAD BROKEN AND PLACED UNDER THE TWO SEPARATE TOP TERMINALS. A BARRIER IS PROVIDED TO PREVENT BOTH LEADS FROM
BEING PLACED UNDER THE SAME TERMINAL.

NOTICE:

 THE THREE PULSE TEMPORAL PATTERN IS TO BE USED FOR EVACUATION USE ONLY.
 THE SOUND OUTPUT FOR THE TEMPORAL 3 TONE IS RATED LOWER SINCE THE TIME THE HORN IS OFF IS AVERAGED INTO THE SOUND OUT PUT RATING. WHILE THE HORN

IS PRODUCING A TONE IN THE TEMPORAL 3 MODE ITS SOUND PRESSURE IS THE SAME AS THE CONTINUOUS MODE. UNITS HAVE BEEN TESTED TO 0°C, 49°C AND 93%
HUMIDITY.

* Operating the horn in this mode at this voltage will result in not meeting the minimum ANSI/UL 464 sound level required for public mode fire protection service. These settings are acceptable

only for private mode fire alarm signaling use. Use the high dBA setting for public mode applications (the chime tone is always private mode).
