ST AND HS SERIES
UL 1971 COMPLIANT
CAN/ULC S526-M87 Compliant
VISIBLE AND AUDIBLE/VISIBLE SIGNALING APPLIANCES
I. INTRODUCTION
The Gentex Model ST/HS, strobe and horn/strobe, is a high quality visible (ST) or audible/visible (HS) signaling appliance. 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 or audible/visible,
depending on the model, notification signal for the purpose of life safety and property protection. This appliance is ideal for hotels, apartments,
hospitals, rest homes or wherever dependable alarms are required. The strobe is listed in compliance with UL 1971, Signaling Appliances for the
Hearing Impaired and CAN/ULC S526-M87 Visible Signal Devices for Fire Alarm Systems (15/75 Cd model is additionally listed in compliance with
UL 1638).
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
ST/HS is intended for indoor installations only. This appliance is not weatherproof 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 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 (Fig.1). 4" square outlet boxes, 2-gang masonry boxes or non-metallic 2-gang switch
boxes with a minimum depth of 1½" may also be used with the 4" mounting plate (Fig.2). Conduit entrance to boxes should be selected to insure
sufficient wiring clearance.
1. Mount a box for each remote signaling appliance.
2. Run a minimum 18 gauge insulated 2 or more conductor cable.
NOTE: 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 AVS44 is permitted to synchronize and/or mute the strobe and horn.
IV. WIRING
Fig. 3: Wiring diagram for independent synchronized strobes and horn.
Using this method you may:
1. Use only two wires to synchronize the temporal horn and strobe with the ability to mute the horn (J1 and J2 in place on the HS).
2. Mute the horn only when the temporal horn option has been selected.
Wiring diagram for synchronized parallel (unison) horn/strobe operation.
Using this method you may:
1. Use only two wires to synchronize the temporal horn and strobe without the ability to mute the horn (J1 and J2 in place on the HS).
2. Choose either temporal or continuous horn with the temporal horn synchronized (Fig.6).
3. Also wire the control module (AVS44) to only the strobe input power terminals, set the horn to continuous mode (Fig.6) and power it from a march
time source. NOTE: For this option, J1 and J2 on the HS (Fig.6) must be removed to isolate power to the audible and visible portion of the circuit.
Fig. 3
Fig. 4 and Fig. 5: 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. Leave jumpers J1 and J2 in place on the HS (Fig.6) to power both the audible and visible from a single pair of
power wires (Fig.4). If you wish to power the horn and strobe from independent sources of power, remove J1 and J2 on the HS (Fig.6) and connect
power to the appropriate terminals (Fig.5).
CAUTION: When using only a single pair of terminals to power the strobe and horn (J1 and J2 in), the in/out
wiring must be under the same terminal. Failure to do so may result in damage to your signal.
NOTE: INSTALLATION IN CANADA - All Canadian installations should be in accordance with the Canadian
Standard for the Installation of Fire Alarm Systems - CAN/ULC S524-01 and the Canadian Electrical Code, Part 1.

V. CHECKOUT AND TROUBLESHOOTING
1. Supply power to the system control panel. The auxiliary signaling appliances in the system should not be activated.
2. If the signal is activated:
· Check all smoke and fire detectors in the system to make sure they have not been activated.
· Check all wiring connections to make sure the signal detection circuits are not reversed or shorted together. Check wire color codes and traces.
· Verify that the jumpers are properly set on both the control module and signal appliance. If the jumper on the AVS44 is as shown in Fig. 3, the
horns will not produce any sound unless there is an input to the H+ and H- terminals on the control module.
3. To test the signal appliances, trip the auxiliary panel or activate the alarm circuit at the main control panel or activate one of the fire detection units in
the system. All auxiliary signals should be activated.
4. An operational test on this product should be conducted in accordance with National Standards or at a minimum annually and more often if dictated
by local and state codes or authorities having jurisdiction.
