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. This proximity
switch MUST be mounted in the same room as the release
device.
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.
