Federal Signal's Model SS2000 is a versatile, user-friendly and economical siren controller that supports one-way communication with the option of two-way communications using DTMF or FSK encoding. Command sequences are programmable and stored in non-volatile memory chips for retention, even when electrical power is disrupted.
Power is supplied by a standard 120VAC wall outlet and can be backed up with a user supplied 12VDC battery and charger.
The Model SS2000 features a four-line backlit liquid crystal display (LCD), full DTMF keypad and 18 user-programmable function keys. Four LEDs are used to indicate the status of the optional printer, radio frequency (RF) carrier detection, key press and one miscellaneous function. A key lock is provided to secure the controller's key pad from unauthorized access.
As a status monitoring device for electronic sirens, the Model SS2000 or SS2000T monitors AC power, intrusion, amplifiers and drivers; operating current, charger, battery and audio A and B lines.
As a status monitoring device for mechanical sirens, the model SS2000 monitors AC power, intrusion, operating current, battery and rotation.
Federal Signal's Model SS2000T DTMF Encoder/Controller or SS200D FSK Encoder offer many extended benefits to any radio controlled signaling device. This unit automatically reports siren/power failures and electronically checks sirens through report-back systems, eliminating the need for personnel at siren sites.
