Potter AVSM SYNCHRONIZATION CONTROL MODULE Manual

AVSM SYNCHRONIZATION MODULE CAN ULC COMPLIANT CAN ULC LISTED PRODUCT INFORMATION IS FOUND ON PAGE 4 INTRODUCTION 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 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 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 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 the control module as shown in the following drawing the module will control the power to the units to produce the synchronized operation 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 THE FACTORY FEATURES OF THE GANGABLE AVSM CONTROL MODULE Slave control modules sync input is wired to the master control module output as an ordinary signal This allows the user to determine which module will act as the master and which will act as the slave s Electrically isolated control module sync input allows slave control modules to be connected across separate power supplies and panels Wiring between sync modules to maintain synchronized operation sync and terminals is supervised Sync input terminals and horn input terminals present a load of 7mA at 24VDC to the power supply Slave control module sync terminals are connected to the output terminals of the 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 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 sync control module in the same manner as an ordinary signal must be reset to the module to reestablish slave mode operation and their corresponding zones are placed into mute mode 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 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 FOR

If only one set of input terminals are used they must be IN1 OUT1 and NEG1 for the control module to operate The master control module will not have any wiring connected to its sync input terminals establishing it as the master module Doing so will cause all modules to operate ELECTRICAL SPECIFICATIONS 24VDC Max Current mA 24VFWR Max Current mA 12VDC Max mA 12VFWRMax Current mA DC VOLTAGE RANGE LIMITS 8 17.5V AND 16 33V FWR VOLTAGE RANGE LIMITS 8 17.5V AND 16 33V THIS PRODUCT WAS ONLY TESTED TO THE STATED VOLTAGE DO NOT APPLY 80 AND 110 OF THIS RANGE FOR SYSTEM OPERATION UNITS HAVE BEEN TESTED TO 0 49 AND 93 HUMIDITY The AVSM is to be connected only to circuits that provide continuously applied voltage Do not use this module on coded or interrupted circuits in which the voltage is cycled on off The AVSM has terminals which can accept wire sizes from 12 to 18AWG with two wires per terminal The AVSM control module must be placed before the signals in the loop which are intended to be synchronized and or The horn input terminals on the AVSM presents a load of 7mA to the NAC When wired in the two wire configuration the for both the strobe and horn current are placed solely on the strobe signal circuit DO NOT USE LOOPED WIRE UNDER THE TERMINALS BREAK WIRE RUN TO PROVIDE SUPERVISION OF DO NOT EXCEED 10 OHMS OF RESISTANCE BETWEEN SIGNALS OR 20 SIGNALS PER LOOP DO NOT EXCEED 3
