The D8130 Door Release Module is an accessory for fire alarm control panels (FACPs) that controls system functions commonly required in National Fire Prevention Association (NFPA) 72 fire alarm installations. Two independent Form C dry contacts, each rated at 5 A, connect low-voltage circuits to magnetic door holders, pilot relays, or contactor units for function control.

Typical applications are:

• releasing fire doors, emergency exit doors, and stairwell doors
• elevator recall
• HVAC control

Contact Activation

The control panel indicating output activates the contacts of the D8130. A red Alarm Input LED indicates contact activation.
The duration of the contact activation follows the programmed indicating circuit time. Use a jumper to set the contact activation to be instant or delayed by 14 sec when there is an alarm condition. With the delay option selected, a 14 sec delay also occurs upon restoral. This delay feature is useful for momentary bell tests.

• Two Form C (5 A rated) contacts
• Remotely controls fire system devices
• Instant or delayed relay activation and restoral
• Relay closure follows indicating circuit duration
• Disable switch supervised for system testing

If the user silences the alarm output, the D8130 contacts deactivate. Latching features must be provided for pilot relays or contactor units requiring control beyond the programmed indicating device time or after manual silencing of the indicating circuits

Supervised Disable Switch

To facilitate fire alarm installation testing, the D8130 Module contains a supervised disable switch that prevents operation of the relay contacts. An amber Disable LED indicates when the switch is in the disable position. Connect one or more D8130 modules to any unused 1 kΩ zone or point of the control panel to detect module disabling.
A trouble is indicated when the D8130 switch is in the disable position, and a restoral signal is sent when the switch is returned to the normal position. (Refer to the control panel's Program Entry Guide for details on programming a trouble signal for an open or short condition.) When the contacts are activated with the switch in the normal position, no trouble indications are sent to the control panel.

Release Contact Outputs

A normally-open (NO) terminal, a normally-closed (NC) terminal, and a common (COM) terminal are provided for each D8130 contact. In the inactive state of the contact, the NC terminal has continuity with the COM terminal. In the active state of the contact, the NO terminal has continuity with the COM terminal.
