Potter AVSM Mode D'emploi

ADDITIONAL CAN/ULC LISTED PRODUCT INFORMATION IS FOUND ON PAGE 4
I. INTRODUCTION
The Potter Electric Signal Company Model AVSM control module is designed to provide an easy way to synchronize multiple strobes and horn/strobes using only two wires. The AVSM is
compatible with the MHT-1224 Series, SPKSTR Series, CSPKSTR Series, CS-24/CHS-24 Series, CCS-24/CCHS-24 Series Colored Lens Series, EH-24/S24/HS24 Series, S-24-WP/
HS-24-WP/SLP-24-WP/HSLP-24-WP Series, CS-24-WP/CHS-24-WP/CSLP-24-WP/CHSLP-24-WP Series, S-24/HS-24 Series and CS-24/ CHS-24 Colored Lens Series. The control module
has the capability to synchronize multiple horn signals with a code 3 temporal pattern, along with the ability to silence the horn while allowing the strobes to continue to flash. By
incorporating the control module as shown in the following drawing, the module will control the power to the units to produce the synchronized operation.
NOTICE: WHEN USING TWO WIRE OPERATION, SWITCHES 1 AND 2 MUST BE IN THE ON POSITION. SWITCHES ON THE SIGNALS ARE IN THESE POSITIONS WHEN SHIPPED
FROM THE FACTORY.
II. FEATURES OF THE GANGABLE AVSM CONTROL MODULE
w Slave control modules' sync input is wired to the master control module's output as an ordinary signal. This allows the user to determine which module will act as the master and which
module(s) will act as the slave(s).
w Electrically isolated control module sync input allows slave control modules to be connected across separate power supplies and panels.
w Wiring between sync modules to maintain synchronized operation (sync + and - terminals) is supervised.
w Sync input terminals and horn input terminals present a load of 7mA at 24VDC to the power supply. Slave control module's sync terminals are connected to the output terminals of the
master sync control module in the same manner as an ordinary signal.
w Loss of sync signal on slave module failsafe mode. If a control module set up as a slave loses the sync signal from the master, the slave module will revert to independent operation.
Power must be reset to the module to reestablish slave mode operation.
w The horns on zones controlled by a slave module may be independently muted via the horn input on the slave module. If the master control module receives a mute signal, then all slave
modules and their corresponding zones are placed into mute mode.
w Staggered zone power up with synchronization is possible. If any slave module receives power after the master sync module, all units will re-sync with the master module within four
seconds.
w A green LED status indicator will flash once every four seconds if zone 1 is operational. The LED will flash twice every four seconds if zones 1 and 2 are operational.
