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.
