Gentex The Gentex Model ST/HS strobe and horn/strobe ST/HS Manuel D’Utilisation
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.

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.
pulsing signaling circuits. However, use of the AVS44 is permitted to synchronize and/or mute the strobe and horn.
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
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.

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.

Using this method you may:
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
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.
