MRI‐4003‐R Relay Base
ABOUT THIS MANUAL
This manual is included as a quick reference for installation
and should be left with the owner/operator of this
equipment. For further information on the use of this
device with a FACP, please refer to the panel's manual.
Note: This manual should be left with the owner/operator
of this equipment.
RELAY BASE DESCRIPTION
The MRI‐4003‐R relay base is designed to meet UL268/ULC
S529 requirements for smoke detector, UL521/ULC S530
requirements for heat detector.
The MRI‐4003‐R must be used with a compatible Secutron
control panel. The device can control one independent
circuit while using one address.
The MRI‐4003‐R provides one form C (SPDT) contact rated
at 2A at 30Vdc, or 0.5A at 125Vac and a compatible panel
can switch discrete contacts by code command. Circuit
connections to the relay contacts are not supervised by the
base. MRI‐4003‐R supports group activation capability for
fast reaction time.

CAUTION FOR SYSTEM SUPERVISION, FOR ALL TERMINAL TAPS, DO NOT USE LOOPED WIRE UNDER TERMINALS. BREAK WIRE RUN TO PROVIDE SUPERVISION OF CONNECTIONS. ATTENTION NE PAS UTILISER DE FILS EN BOUCLE SOUS LES BORNES. POUR FOURNIR UN BON SUIVI DES CONNEXIONS. INTERROMPRE LA CONTIUITÉ DES CÂBLES. Step 1 MOUNTING Secutron recommends spacing speaker strobe appliances in compliance with CAN/ULC S524 and/or NFPA72. Step 2 The mounting plate is compatible with 3” by 2” single gang device boxes, 3-3/4” by 4” double gang boxes, 4” by 2” single gang utility boxes, standard 4” by 4” boxes, and standard 4” octagon boxes. 1. Attach the mounting plate to electrical box with two mounting #8‐32 x 3/4" screws. Step 3 2. Slide down the sounder base enclosure until the connection blades touch the clips on the mounting plate. 3. Secure the mounting plate with securing M3 x25 mm screws.

See figures 7. Figure 7 ADDRESS TAB INSERT Breakaway Insert address tab The detector can then be placed on the top base using the following steps (figure 8): 1. Position the detector centrally on its adapter base ensuring it is level. 2. Rotate clockwise applying gentle pressure. The detector will drop into its keyed location. 3. Continue to rotate clockwise a few degrees until the detector has fully engaged in the adapter base. 4. When the detector is firmly engaged, check the alignment of the raised reference marks on the detector and on the base (figure 9).
