Before Installing

This information is included as a quick reference installation

guide. Refer to the appropriate Notier control panel installation

manual for detailed system information. If the modules will be

installed in an existing operational system, inform the operator

and local authority that the system will be temporarily out of ser-

vice. Disconnect power to the control panel before installing the

modules.

NOTICE: This manual should be left with the owner/user of this

equipment.

General Description

The FRM-1 Relay Control Module is intended for use in intelligent,

two-wire systems where the individual address of each module is

selected using the built-in rotary switches. It allows a compatible

control panel to switch discrete contacts by code command. The

relay contains two isolated sets of Form-C contacts, which operate

as a DPDT switch and are rated in accordance with the table in

the manual. Circuit connections to the relay contacts are not su-

pervised by the module. The module also has a panel controlled

LED indicator. This module can be used to replace a CMX-2 mod-

ule that has been congured for Form-C operation.

Compatibility Requirements

To ensure proper operation, this module shall be connected to a

compatible Notier system control panel (list available from Noti-

er).

Mounting

The FRM-1 mounts directly to 4″ square electrical boxes (see Fig-

ure 2A). The box must have a minimum depth of 2

mounted electrical boxes (SMB500) are available from Notier.

Wiring

NOTE: All wiring must conform to applicable local codes, ordi-

nances, and regulations. When using control modules in
nonpower limited applications, the CB500 Module Bar­rier must be used to meet UL requirements for the sepa­ration of power-limited and nonpower-limited terminals

1. Install module wiring in accordance with the job drawings and

N500-47-00 1 I56-1170-04

and wiring. The barrier must be inserted into a 4″x4″x2
/8″ junction box, and the control module must be placed
into the barrier and attached to the junction box (Figure
2A). The power-limited wiring must be placed into the
isolated quadrant of the module barrier (Figure 2B).

2. Set the address on the module per job drawings.
Note: Some panels support extended addressing. In order to

set the module above address 99 on compatible systems, care­fully remove the stop on the upper rotary switch with thumb in
the direction shown in Figure 1.

3. Secure module to electrical box (supplied by installer), as
shown in Figure 2A.

All relay switch contacts are shipped as shown in Figure 3, but may have transferred during shipping. To ensure that the switch contacts
are in their correct state, modules must be made to communicate with the panel before connecting circuits controlled by the module.

IF ANY WIRING TO TERMINALS 3 – 9 IS NONPOWER
LIMITED, THE CB500 BARRIER IS REQUIRED. THE CB500
INCLUDES A NONPOWER LIMITED LABEL, WHICH MUST
