Conettix C900V2 Installation Guide

2.3Input Functions

The C900V2 has three inputs monitored by analog- to-digital (A/D) converters:

•Input 1 (IN1): Used as an end-of-line (EOL) supervised loop. If input status reports are enabled by the receiver using the Conettix D6200 Programming/Administration Software (referred to as D6200 Software), any voltage below 1.66 VDC is sent as a short-circuit message to the D6600. Any voltage above

3.33 VDC is sent as an open-circuit message. Input 1 must be EOL-terminated with a 10 k￿ resistor. Refer to the D6600/D6100i Computer Interface Manual (P/N: 4998122703) for Event Messages to automation software.

•Input 2 (IN2): Used for Intercept Inhibit. If Input 2 rises above 5.5 VDC, the C900V2 is immediately forced into Fallback Mode for at least 2 minutes. Input 2 must go low for at least 5 seconds to be considered low. If Input 2 is not used, allow it to remain disconnected.

•Input 3 (IN3): Used for Intercept Override. If Input 3 rises above 5.5 VDC for 5 seconds, the C900V2 enters Fallback Mode. If Input 3 goes low, the C900V2 returns to Intercept Mode. If this input is connected to a ground start relay output, the C900V2 remains in Intercept Mode, except to allow the dialer to dial. Input 3 cannot force Intercept Mode if the C900V2 is in Fallback Mode because of an error, a command, or a high signal at Input 2. If this input is not used, allow it to remain disconnected.

You cannot use Inputs 1, 2 and 3 for UL Fire Listing. You can use the inputs for other purposes.

•Output 2 (OUT2): Active (open) when the receiver works properly, and closed when the receiver does not respond to or acknowledge a message sent from the C900V2.

Connect Output 2 from the C900V2 to a 24-hour zone on the control panel. This

24-Hour Zone Alarm Report enables the digital dialer, if used, to indicate or sound a failure if the network communications path fails.

•Output 3 (OUT3): Active (open) when the C900V2 is in Intercept Mode.

•Output 4 (OUT4): Controlled by a command from the D6200 Software or receiver. The default is open.

2.5Power Terminal Strip

Terminal		Description
	V (+)		Connect regulated 12 to 24 VDC power to
			this terminal and the – V terminal. This
			power can be supplied by a separate power
			supply or auxiliary power from the control
			panel.
V (–)		12 to 24 VDC return.
			Connect to earth ground.

2.6Telephone Connections

Use two of the RJ-45 telephone connectors to connect to the control panel and to the PSTN. The connector pins are identified in Table 2 and Figure 7.

2.4Output Functions

The C900V2 has four relay contact outputs:

•Output 1 (OUT1): Active (open) when the CPU works properly. If the CPU fails or loses power, Output 1 closes.

Connect Output 1 from the C900V2 to a 24-hour zone on the control panel. This

24-Hour Zone Alarm report enables the digital dialer, if used, to indicate or sound a failure if the C900V2 CPU fails.
