Pre-operational System Testing

DCB, DCFCB and DCFCTB Models

*Note: Deviation levels are cut in half on 12.5 kHz spaced channels.

3. Encode the appropriate DTMF strings and or 2-tone tones required to activate the

desired siren function. Confirm reliable decoding of at least 10 of 10 tries.

4. Plug JP21 back in.

Confirming Controller Auto-Reporting

By toggling one of the following sensor inputs, confirm that the controller sends a

correct report to the SS2000 base controller. Note that with digital systems the

DCFCTDB must be programmed to auto-report the following sense points to perform

this test.

Intrusion

Depress intrusion switch for at least 5 seconds. Release the switch. Verify the door

closed and door open reports we received at the SS2000.

AC Line Voltage

By removing AC power at the service disconnect confirm that a report is generated

within 5 minutes. Confirm that another report is generated when power is restored.

The output sound level of a siren is capable of causing severe hearing discomfort or

permanent hearing damage. Therefore, ALWAYS wear adequate hearing protection

and minimize exposure time when performing any testing or maintenance on the

siren.

Test Activation Codes

Test all siren functions from the siren control point. This test must be performed to

ensure all desired siren functions have been properly entered at the control station and

at the siren site. Request a report from the control station during the siren function.

Verify the report indicates the proper status conditions for the site being tested.
