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.

The D7025 and Control contain static sensitive
components and must be handled with care. Follow
anti-static procedures when handling these products.

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.

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.

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).

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).

Wiring the D7025 Relay Module
•
The two Form C relays can be wired as Normally Closed or Normally Open.
•
Use the ALARM relay for external devices that are required to operate when the Control is in ALARM.
•
Use the TROUBLE relay for external devices that are required to operate when the Control indicates TROUBLE.
•
The Control holds the TROUBLE relay energized in normal standby. 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.
