POTTER Avsm Synchronization Control Module

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.

FEATURES OF THE GANGABLE AVSM CONTROL MODULE

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).
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’s sync terminals are connected to the output terminals of the master sync control module in the same manner as an ordinary signal.
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.
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.
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.
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.

WIRING FOR MULTIPLE CLASS A CIRCUITS AND USE OF A SLAVE MODULE

warning

The master control module must be powered at the same time or prior to the slave modules for proper operation.
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 independently.

NOTICE: 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 RANGE(S); DO NOT APPLY 80% AND 110% OF THIS RANGE FOR SYSTEM OPERATION. UNITS HAVE BEEN TESTED TO 0°C, 49°C AND 93% HUMIDITY.
CAUTION: 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 and 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 controlled.
The horn input terminals on the AVSM presents a load of 7mA to the NAC. When wired in the two wire configuration, the load 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 CONNECTION.
DO NOT EXCEED 10 OHMS OF RESISTANCE BETWEEN SIGNALS OR 20 SIGNALS PER LOOP.
DO NOT EXCEED 3 AMPS CONTINUOUS OR 5 AMPS PEAK LOAD CURRENT.
THIS APPLIANCE WILL NOT OPERATE WITHOUT ELECTRICAL POWER. AS FIRES FREQUENTLY CAUSE POWER INTERRUPTIONS, POTTER ELECTRIC SUGGESTS YOU DISCUSS FURTHER SAFEGUARDS WITH YOUR LOCAL FIRE PROTECTION SPECIALIST.
