gENERAL DESCRIpTION

FIgURE 1: INSTALLATION OF SYNC-1

The SYNC-1 Accessory Card is designed to operate with the Six Supervised
Control Module. It works with the SpectrAlert series of horns, strobes, and
horn/strobes to provide a means of synchronizing the temporal-coded horns,
synchronizing the one-second flash timing of the strobe, and silencing the
horns of the horn/strobe combination over a two-wire circuit while leaving
the strobes active. Each SYNC-1 Accessory Card consists of three electrically
isolated synchronization circuits. Although they are isolated from each other,
all three circuits are synchronized with respect to each other. A SYNC-1 Ac­cessory Card enables a Six Supervised Control Module to synchronize a maxi­mum of three Class A or six Class B notification appliance circuits (NACs).

NOTE: This manual should be left with the owner/user of this equipment.

When used with the SYNC-1 Accessory Card, the Six Supervised Control Mod­ule can accommodate a maximum of three power supplies limited to a maxi­mum of 3 Amp each. The SYNC-1 Accessory Card control circuitry can only
be energized by connecting power supplies to the “PS” terminals at the even

INSTALLATION OF SYNC-1 ACCESSORY CARD

Install two screws into the holes on the bottom center of the Six Supervised
Control Module. On the front side of the board, install two standoffs onto
these screws. The SYNC-1 Accessory Card plugs into the pins of the Six Super­vised Control Module. The pins on the module are labeled “SYNC GENERA­TOR.” Remove the three large shunts on the Sync Generator pins. Line up the
holes on the accessory card with the pins on Six Supervised Control Module.

CAUTION: Ensure the pins and holes are lined up correctly or the SYNC-1
accessory card will not operate properly. Push down firmly on the accessory
card. Install two screws into standoffs to secure the board.

the SYNC-1 Accessory Card is powered by the supply connected to the “PS”
terminals at position (+0). Therefore there must be a supply connected to

(+0) for the SYNC-1 Accessory Card to be operational.

The SYNC-1 Accessory Card used with a Six Supervised Control Module is
limited to a maximum of three power supplies, therefore each circuit pair
(+0/+1, +2/+3, +4/+5) must share a supply in order for all NACs to
be powered. Due to supply sharing the maximum load on a Class A NAC is
limited to 3A while the maximum load on a pair of Class B NACs is limited
to 3A total.

NOTE: Power Supply Monitoring must be disabled (on the Control Module)
when using the SYNC-1 Accessory Card on the Six Supervised Control Module.
Refer to the Six Supervised Control Module installation manual for more detail
regarding its configuration and wiring requirements.

FIgURE 2: CONNECTINg TWO SYNC-1 CARDS (CLASS B OpERATION, ONE pOWER SUppLY USED)

To interconnect SYNC-1 Accessory Cards wire the Slave and Horn connections
as shown in Figure 2. The slave wires will synchronize all NACs correspond­ing to the interconnected boards. Any SYNC-1 which has no connections to its
slave in terminals will operate as a master. It will generate a signal which will
be duplicated by all interconnected units downstream. The horn wires will en­able horn control on all NACs corresponding to the interconnected boards.

Horn control also requires a silenceable NAC circuits to be wired to the horn
in terminals of the master SYNC-1 Accessory Card as shown in Figure 3.

A maximum of 11 Slaves Sync-1 Cards can be connected to a Master Sync-1
Card, totalling 12.

C0123-01

All horn and slave wiring interconnecting SYNC-1 accessory cards must be
contained within the same enclosure. If multiple enclosures are used they
must be located within 20 feet of each other with all horn and slave wiring be­tween enclosures routed inside of conduit. This conduit should be grounded
metal containing no other field wiring.
