EST EA752-2 Montageanleitung

EA752-2 Monitored Dual Output Module

Installation Sheet

Description

The EA752-2 provides two conventional output circuits (Circuit

1 and Circuit 2) for operating polarized sounders, visual

indicators, and controls for ancillary equipment. Output 1 and

Output 2 share the same address and therefore switch on and

off at the same time.

The module comprises a front plate and a backbox. The front

plate houses the electronic components and plugs into the

backbox. The backbox provides the screw terminals for

connecting the field wiring.

The bicolor LED on the front plate indicates the status of the

module (off = normal condition, red = active condition, amber =

fault condition). There is space provided next to the LED to

attach an address label, if desired.

WARNING: This module will NOT operate without electrical

power. As fires frequently cause power interruption, we

suggest you discuss further safeguards with your local fire

protection specialist.

Installation

1. Remove the front plate from the backbox.

2. Drill out center hole in the backbox and run wires into the

module.

3. Remove appropriate knockouts on the backbox for

mounting to a conduit box. Mount the backbox to the

conduit box.

4. Make all wiring connections as shown in the wiring

diagram (Figure 2).

5. Set the address switch for the module. See “Address

switch settings” below (Figure 1).

6. Attach the address label to the indent that is on the front of

the module.

7. Secure the front plate to the backbox with the two screws

provided.

Address switch settings

SW1 is used to assign device addresses. Each switch segment

has a decimal value as shown in Figure 1.

The sum of all the switch segments in the ON position

determines the device address. You can set the device

address to any value between 001 and 127 that is not used by

another device on the same loop. For example, to select a

device address of 007 you must set SW1-1, SW1-2, and SW1-

3 to the ON position and the remaining switch segments to the

OFF position.

Notes

1. Screened cable.

2. EOLR required if circuit is not used.

3. Terminal marking (plus/minus)

indicates signal polarity when the

circuit is active. The polarity

reverses when the circuit is not

active.

4. Signal source must be CE and

EN54-4 compliant. The jumper must

be connected.

5. Each output circuit provides up to 1

A at 24 VDC. Each output circuit

has a 1 A fuse. Fuses are monitored

by the panel.

6. Devices connected to the output

circuit must be polarized as shown.

If non-polarized devices are used,

insert a 1N4002/7 diode in the

positive leg of each device, with the

stripe facing the device. For

inductive loads (relays etc), fit a

Bipolar Transient Protector

(P/N 235196P) across the coil.

7. Attach the supplied ferrites to cables

as shown in Figure 2 (internal to the

module).

8. The following ferrite core needs to

be fitted to all cables (externally to

the module): TDK ZCAT3055-1330.
