Six-Circuit Addressable Control Module and SYNC-1 Accessory Card
Description
Gamewell's SCM-SS SmartScanTM 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 applications 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 external 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 external power supply against short-circuit conditions on the NAC. When an alarm condition occurs, the relay which connects the external supply to the NAC will not be allowed to close if a short-circuit condition condition currently exists on the NAC. Additionally, 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 SCMSS with additional functionality with compatible System Sensor SpectrAlert(R) audio/ visual devices.

Listings
Listings and approvals below apply to the SCM-SS Six-Circuit Addressable Control Module and SYNC-1 Accessory Card. In some cases, certain modules may not be listed by certain approval agencies, or listing may be in process. Consult factory for latest listing status. * UL Listed: file S521. * CSFM approved: file 7300-1288:169. * MEA approved: file 368-01-E Vol. II.
SYNC-1 Accessory Card
The SYNC-1 accessory card is designed to operate with the SCM-SS. It works with the SpectrAlert(R) 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: 32F to 120F (0C to 49C). Wire size: 12 to 18 AWG (3.1 to 0.78 mm). Operating voltage range: 11 to 30 VDC FWR, filtered or unfiltered. Refer to notification appliance installation instructions for number of notification appliances and wire size. Compatible A/V devices: H12/24, HC12/24, MA12/24D, PA400, S12__, S24__, SC24__, P12__, P24__, PC24__, SP2C24__, SP2R24__, SP2W24__, DS2475___. Refer to device data sheets for model specifications.

FIGURE 1: Mounting the SYNC-1 accessory card to the SCM-SS module.
Module setup: Before installing the accessory card on the SCM-SS module, add the shunt to the board where indicated if any horns are required to sound in temporal pattern. Parts included with SYNC-1: two shunts, four screws, and two standoffs. See installation instructions for details on mounting and wiring the accessory card and module.
