Six-Circuit Addressable Control Module
and
SYNC-1
Accessory Card
Description
Gamewell’s
SCM-SS SmartScan™
six-circuit addressable control
module
provides intelligent alarm
systems with supervised monitoring
of wiring to load devices that require
an external power supply to operate,
such as horns, strobes, or bells. Each
module is intended for switching ap-
plications involving AC, DC, or audio,
which require wiring supervision.
Upon command from the control
panel, the SCM-SS will disconnect
the supervision and connect the ex-
ternal power supply across the load
device.
The first module is addressed from
01 to 94 while the remaining modules
are automatically assigned to the next
five higher addresses. Provisions are
included for disabling a maximum of
three unused addresses. Each SCM-SS module has terminals for connection to an
external supply circuit for powering devices on its notification appliance circuit. One or
multiple power supplies or amplifiers may be used.
Each SCM-SS module features a short-circuit protection monitor to protect the exter-
nal power supply against short-circuit conditions on the NAC. When an alarm condi-
tion occurs, the relay which connects the external supply to the NAC will not be al-
lowed to close if a short-circuit condition condition currently exists on the NAC. Addi-
tionally, an algorithm is incorporated to find shorts when the module is active. The
SCM-SS module will close all circuits that are not shorted to find the NAC with the
problem.
Each SCM-SS module has panel-controlled green LED indicators. The panel can cause
the LEDs to blink, latch on, or latch off. The
SYNC-1 accessory card
provides the SCM-
SS with additional functionality with compatible System Sensor SpectrAlert® audio/
visual devices.

SYNC-1 Accessory Card
The SYNC-1 accessory card is designed to operate with the SCM-SS. 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 is capable of
synchronizing six Class B circuits or three Class A circuits.
Maximum load on a loop:
3 A.
Operating temperature:
32°F to 120°F (0°C to 49°C).
Wire size:
12 to 18 AWG (3.1 to 0.78 mm²).
