Introduction

Two 866 NAC Modules

5.1Description

Each 866 provides one style W indicating circuit for supervising listed polarized notification appliances, such as bells, strobes, and horns. See Table 1: Notification Appliances for a list of approved notification appliances.

5.2Connection

Each 866 module is pre-installed on the removable backplate using the standard three-hole configuration. The modules are factory pre-wired to each other and the XR2500F panel. Refer to the figure below and to Figure 2: XR2500F System for wiring connections.

Connect a 12 or 24 VDC regulated, power limited power supply listed for Fire Protective Signaling Systems to terminals 2 and 4 of each module to provide Notification appliance power. Connect notification appliances to terminals 5 and 6 of each module. Each module provides a zone of notification and can be activated separately.

5.3Bell Silence/Bell Trouble

A bell silence switch on the 866 module is provided to prevent indicating devices from sounding during system testing. When the Silence position is selected, a 15-second delay occurs before the 866 bell trouble contacts (terminals 7 and 8) open. Select the Normal position after testing to return the 866 module to normal operation.
