WIRING INSTRUCTIONS
Verify wiring configuration with that recommended by door
manufacturer for use of this product with specific door and
accessories being utilized. The use of 18 AWG wire is
recommended.
1. Close fire door prior to ANY wiring.
2. Turn off power supply sources for the release device as well as
the door operator, before beginning.
3. Verify voltage rating of release device to power source being
utilized. Voltage is indicated on the side of the unit. Verify that
power is disconnected before proceeding.
4. When powering the device from 120Vac line voltage, locate the
3-position terminal block mounted within the device enclosure.
Connect 120Vac (single phase) power source inputs to
terminals L1 (line) and L2 (neutral) of the terminal block
(Figure 1). The third position is used for earth ground.
5. When powering the device from 24Vac or 24Vdc power,
connect to terminal board positions 1 and 2 (Figure 2).
Observe proper polarity.
6. Do not connect line power or battery until all field wiring is
complete per the following pages. The battery provides backup
power in the event of a loss of line voltage and prevents the
release of the fusible link assembly and the resulting door
closure. A pulsing sounder occurs when the battery is
disconnected or when replacement is required. The battery also
provides power to the various ancillary devices (i.e., smoke
detectors, horn/strobes, etc.).
To reduce the risk of SEVERE INJURY or DEATH:
• ALL electrical connections MUST be made by a qualified
individual.
• Disconnect power at the fuse box BEFORE proceeding. Release
device MUST be properly grounded and connected in
accordance with local electrical codes.
• Installation of ALL wiring and connections, including Class 1
and Class 2 circuits, shall be performed in accordance with,
but not limited to, the latest NFPA, UL and N.E.C. standards
and codes. In addition, ALL installations subject to Canadian
standards shall be performed in accordance with the Canadian
Electrical Code, Part I, with respect to wiring material type,
wiring gauge related to power capacity requirements and
circuit length and wiring methods.
• ALL power wiring should be on a dedicated circuit and well
protected. The location of the power disconnect should be
visible and clearly labeled.
• ALL power and control wiring MUST be run in separate
conduit.
• 120Vac should ONLY be attached to the 3-position terminal
block mounted within the enclosure.
• DO NOT disconnect battery or remove battery fuse while unit
is under power, the door will drop.
