LOW FReQUeNCY VISIBLe AND/OR AUDIBLe SIGNALING APPLIANCe
I. INtRODUCtION
The Gentex models GHLF and GHSLF are high quality low frequency audible and/or visible signaling appliances. This appliance is intended to provide a low frequency audible or audible/
visible, depending on the model, notification signal for the purpose of life safety and property protection. The GHSLF is a fixed candela unit; the candela intensities which can be ordered are
15 Cd, 110Cd and 177Cd. The GHSLF strobe is listed in compliance with ANSI/UL 1971, Signaling Appliances for the Hearing Impaired.
This appliance is ideal for any occupancy that requires notification appliances per the applicable building or fire code or wherever dependable alarms are required. As of January 1, 2014
NFPA 72 requires that audible appliances installed in sleeping areas produce a low frequency alarm signal. For your information, the National Fire Protection Association's (NFPA) Standard 72,
2013 Edition, Chapter 18, Section 18.4.5 Sleeping Area Requirements, states the following:
18.4.5.3 Effective January 1, 2014, audible appliances provided for the sleeping areas to awaken occupants shall produce a low frequency alarm signal that complies with the following:
1) The alarm signal shall be a square wave or provide equivalent awakening ability
2) The wave shall have a fundamental frequency of 520Hz ± 10 percent
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 GHLF and GHSLF are intended for indoor installations only; these appliances are
no
t listed
for
outdoor
or drip proof applications.
Wall mounted 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. Insert mounting screw as
shown and tighten. Cover assembly with the plastic housing.
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. A BARRIER IS PROVIDED TO PREVENT BOTH LEADS FROM BEING PLACED UNDER THE SAME TERMINAL.
IV. AUDIBLe SIGNALING APPLIANCe OUtPUt
w
The three pulse temporal pattern (temporal 3) is to be used for evacuation use only.
w
The standard fire alarm evacuation signal is a three-pulse temporal pattern. The pattern consists of the following in this order:
(1) An “on” phase lasting 0.5 second ± 10 percent
(2) An “off” phase lasting 0.5 second ± 10 percent for three successive “on” periods
(3) An “off” phase lasting 1.5 seconds ± 10 percent
Total cycle lasts for 4 seconds ± 10 percent
w
The sound output for the temporal 3 tone is rated lower since the time the horn is off is averaged into the sound output rating. Units have been tested to 0°C, 49°C and 93% humidity.
w
The four pulse temporal pattern (temporal 4) is to be used for carbon monoxide alarm signal use only.
w
The standard carbon monoxide alarm is a four pulse temporal pattern. The audible carbon monoxide alarm signal shall comply with the following:
(1) Signals shall be a single tone pattern consisting of four cycles of 100 milliseconds ± 10 percent “on” and 100 milliseconds of ± 10 percent “off,” followed by 5 seconds ±
10 percent “off.”
(2) After the initial 4 minutes of alarm, the 5-second “off” time shall be permitted to be changed to 60 seconds ± 10 percent.
w
The four pulse temporal pattern (Temporal 4) can only be obtained on this product when used in conjunction with the Gentex GTSM synchronization module or GTSM synchronization
protocol.
