D7025 Alarm and Trouble Relay Module Installation Guide 1.0 • N.C. Notice C N.O. These instructions are for the installation of the D7025 Alarm/Trouble Relay Module. This module allows the D7022 Fire Alarm Control Panel (FACP) to support two auxiliary Form C relays for connection to external devices. One ALARM relay and one TROUBLE relay are provided. The D7025 plugs into the Control and is powered directly from the Control. These instructions detail procedures to follow in order to avoid personal injury and damage to the equipment. 2.0 N.O.

Installing the D7025 Relay Module Figure 1: D7025 Relay Module Failure to follow the mounting instructions in this installation guide may result in damage to equipment. 16 15 14 The D7025 and Control contain static sensitive components and must be handled with care. Follow anti-static procedures when handling these products. 1. 2. 13 12 11 10 9 The D7025 board mounts on the Control board in the upper right hand corner (see Figure 2). Use the four nylon stand-offs supplied with the D7025 to mount the module to the Control. SILENCE RESET 8 7 Before installing the D7025 Relay Module onto the Control, remove both AC and BATT power from the Control. Make sure that the programming dip switches on the control are set for required operation. SILENCE DISABLE 6 ALARM 1 ALARM 2 5 TROUBLE 1 TROUBLE 2 4 3 SYSTEM FAULT Install the four nylon stand-offs in the holes provided in the Control board (see Figure 2). Avoid bending or flexing the Control board when inserting the stand-offs. Be sure the stand-off tabs are aligned so that they do not touch any components on the Control. Make sure the stand-offs are firmly pressed into the board so that the “ears” can expand out (see Figure 3). 2. Install the D7025 board onto the stand-offs, noting that the connector pins from the Control are properly aligned to install into the connector on the D7025 (see Figure 4). Avoid bending or flexing the boards when pressing them onto the stand-offs. Connect the yellow/green earth ground wire to the ground terminal on the Control terminal strip (see Figure 5).

The “C” and “NC” terminals are connected in normal standby. • Loss of AC power does not activate the trouble relay until the programmed AC fail timer expires. • No additional programming is required. • See Figure 6 for D7025 terminal strip wiring connections.
