I. INTRODUCTION

The Gentex models GEC3-12, GES3-12, GEH12,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 GEC3-12 and GES3-12 are provided with a slider switch which allows for candela intensity selection at the
installation site; the intensities which can be selected are 15Cd, 30Cd, 60Cd or 75Cd. 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 strobe is listed in compliance with ANSI/UL 1971.

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 GEC3-12, GES3-12, GEH-12 is intended for
indoor installations only; this appliance is not listed for outdoor or drip proof applications.
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 90in. (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.
