74-2696: Off Premises Signaling Module 3-OPS. CSI 3-Part Specifications. Large file (>500kB).

FEATURES

• Reverse Polarity Outputs for Alarm Supervisory and Trouble
• Municipal Circuit Operation

GENERAL

The Off Premises Signaling module (3-OPS) is a local rail module in the Excel Life Safety system. The 3-OPS can be configured for old or new styles of reverse polarity central station operation. Removable field wiring terminals on the 3-OPS module facilitate troubleshooting and servicing of field wiring. In addition, any Control Display module can mount to the front of an 3-OPS module.

OPERATION

The 3-OPS Module supports three off premises signaling modes of operation as follows:

� The new style reverse polarity (Fig. 1) allows the 3-OPS module to output three independent reversing polarity signals: alarm, supervisory, and trouble. In each case, an active condition causes the terminal output voltage to reverse. If the central station detects a loss of voltage, the condition is due to a line failure. When configured for new style reverse polarity operation, the 3-OPS Module supports a set of form �C� trouble relay contacts.

� The old style reverse polarity operation (Fig. 2) has only the alarm relay active. In the normal state, the alarm output is 24V dc current limited to 6 mA. In the alarm state, the polarity reverses. If the panel goes into trouble from the normal state, the 3-OPS module removes the voltage from the output terminals and the central station detects a trouble. Alarms always have priority over trouble conditions. Trouble relay contacts must be configured for n.c. operation.

� The 3-OPS module can support a municipal, city-tie connection and provides a terminal for a local energy master fire alarm box (Fig. 3). The 3-OPS module interfaces to a 14-ohm coil and supervises the city-tie connection for open conditions. In this application, trouble relay contacts are configurable for n.o. or n.c. operation.
