FDM-1 Dual Monitor Module
INSTALLATION AND MAINTENANCE INSTRUCTIONS
Before Installing
This information is included as a quick reference installation
guide. Refer to the 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 service. 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 Dual Monitor Module is intended for use in intelligent, two
wire systems. It provides two independent 2-wire initiating device
circuits (IDC), at two separate, consecutive addresses. It is capable
of monitoring normally open contact fire alarm and supervisory
devices, or either normally open or normally closed security de-
vices. The module has a single panel controlled red LED.
Compatibility Requirements
To ensure proper operation, this module shall be connected to a
compatible Notifier system control panel (list available from Noti-
fier).
Mounting
Mounts directly to 4” square electrical boxes (see Figure 2A). The
box must have a minimum depth of 2
1
/
8
”. Surface mounted elec-
trical boxes (SMB500) are available from Notifier.
Wiring
NOTE:
All wiring must conform to applicable local codes, or-
dinances, and regulations. This module is intended for
power limited wiring only.
1. Install module wiring in accordance with the job drawings and
appropriate wiring diagrams.
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.
Note: Monitor module L (using terminals 6 and 7) re-
sponds at the address set on the code switches. Monitor
module H (using terminals 8 and 9) will automatically re-
spond at the next higher address. For example, if the code
switches are set to 76, module L will respond at address 76
and module H will respond at address 77. Use caution to
