CONNECTIONS OF INITIATING DEVICES AND ACCESSORIES (cont’d)

Relay Module Installation

In lieu of smoke detectors, the release device may be put into alarm by the fire alarm control panel. Most commonly, a relay module is used as an interface between the fire alarm control panel and the release device. The relay module must provide Form C dry contacts for connection to the appropriate terminals on the release device (Figure 7).

NOTE: When choosing a relay module to activate the release device in an alarm condition, always select one that provides Form C dry contact relays. Do not use any relay module providing or passing any (control) voltage through the contacts into the release device. The passage of voltage through such a relay module into the release device will cause problems with the operation of the device and may damage the device’s terminals and/or circuit board.

OPTIONAL CONNECTIONS

CLOSE DOOR DETECTION OPTION

Connect wiring from N/O electrical loop, using a proximity switch or other similar device with dry contacts, to 7 and 8 (Figure 8). The switch should be placed to engage when the door is in the closed position and so that it will toggle states from its N/O condition (switch closed when door is closed) to a closed condition indicating that the door edge has made contact with desired down position. When the switch is closed by contact from the door, the release device will not activate on alarm, thereby eliminating nuisance gravity drops through the inadvertent release of the fusible link assembly. This option only works as long as power is available to unit. Fail-safe operation is maintained under all operating conditions, and if power is not available to the unit, the fusible link assembly will be released. This is a power-limited, unsupervised circuit. The proximity switch and the release device MUST be mounted in the same room.

RELAY AND TROUBLE OUTPUTS OPTION

Connect wiring from the Alarm Relay Outputs (#11 N/C or #13 N/O and #14 Common) to the appropriate inputs on the fire alarm control panel to provide a signal at the panel when the release device is in an alarm state. Connect wiring from the Trouble Relay Outputs (#14 N/C or #16 N/O and #15 Common) to the appropriate inputs on the fire alarm control panel to provide a signal at the panel that the release device is in a trouble state (Figure 9). If these features are desired, coordinate the interconnection between the Release Device and the Fire Alarm Control Panel with the fire alarm installer.

TROUBLESHOOTING

OPERATIONAL CHECKLIST

POWER

Is the red LED, labeled “Power,” located on the bottom of the enclosure lit?

CHECK THE ALARM

Are the alarm (smoke detection) inputs correct? If not, the release device will not release the fusible link assembly in a fire condition. Conversely, the release device will always release the fusible link assembly when powered or reset.

CIRCUIT BOARD DIAGNOSTIC LEDS

View diagnostic LEDs present on the circuit board located behind the terminal board. Refer to the table below for the status LED indications.

Is the Red LED Lit?

Yes Move on.

No Check power connections at terminal board positions 1 and 2.

Check voltage; voltage should be 24Vdc received from an approved UL 1481 regulated power supply.

Are the Alarm Inputs correct?

Yes Move on.

No Check that it is a dry contact input. There should not be any

voltage on the alarm lines when they are disconnected from the unit.

Check to see if it is tied into an addressable relay module of an alarm panel. At times, noise can be picked up from these modules.

CHECK THE CLOSE DOOR DETECTION

Is the Yellow LED on the bottom of the enclosure lit? If lit, the close limit is active and the device is disabled and will not release the tension on the door spring as the door is in the closed position, activating the proximity switch. If not lit, check wiring instructions in Figure 8.

LED LED Color Description

Disable Yellow The Yellow LED will light when the door reaches the close

limit and activates a proximity switch attached to terminal positions 7 and 8 on the release device. This configuration results in the device not releasing the fusible link assembly in alarm or power loss situations and should only be used when the fire door is kept in a constant closed position.

If the LED does not light when the door reaches the close limit and activates the proximity switch, then check that the proximity switch has been activated and that the switch is set to normally open (N.O.). Check to make certain that the switch is attached to terminal positions 7 and 8 on the release device.

Power Red If the Red LED is lit, then the line power is connected and

switched “on.”

If the LED does not light when power is applied, check that power is connected as described in the installation manual electrical connections.

MAINTENANCE

To avoid SERIOUS PERSONAL INJURY or DEATH from electrocution, disconnect ALL power BEFORE performing ANY maintenance.

WARNING

MAINTENANCE REQUIREMENTS

The release device has no scheduled maintenance requirements. The unit has been designed and tested for use in dry, indoor locations.
