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 devices. The module has a single panel controlled red LED.

COMPATIBILITY REQUIREMENTS

To ensure proper operation, this module shall be connected to a compatible
Silent Knight system control panel (list available from Silent Knight).

MOUNTING

Mounts directly to 4-inch square electrical boxes (see Figure 2). The box
must have a minimum depth of 21/8 inches. Surface mounted electrical boxes
(SMB500) are available from Silent Knight.

ALL WIRING SHOWN IS
SUPERVISED AND POWER LIMITED

NOTE: All wiring must conform to applicable local codes, ordinances, 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: Monitor module L (using terminals 6 and 7) responds at the ad-

dress set on the code switches. Monitor module H (using terminals 8 and

9) will automatically respond 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 avoid duplicate ad­dressing of modules on the system.

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