. Overview
Each 8900 EMR series unit contains a door closer, hold open
electromagnet, and smoke detector. The unit can be used as
a single installation or as a series of singles powered from one
or more power supplies. When a series of 8900 EMR units are
wired together in a run, groups of up to 5 units may be
interconnected. Interconnection is accomplished through
terminals #4 and #15 and results in all units alarming when
any one of them senses smoke. In turn, all associated hold
open electromagnets are de-energized. Within any run of
detectored units, it is permissible to form as many
interconnected groups as the total power supply amperage
will allow; but, again no more than 5 units can be
interconnected together.
. Preparation notes
Any detectored 8900 EMR series unit can be connected to an
auxiliary EMF non-detectored unit, or remote detector, or
both. It can be a single installation or part of any of the
multiple arrangements described above. An auxiliary unit
(double door applications) is a companion to the main unit,
and its electromagnet de-energizes along with the main unit.
A remote open area detector sensing smoke alarms the 8900
EMR to which it is connected and any other 8900 EMR to
which it is interconnected.
Single installations or groups of installations can be
connected to the alarm initiation circuit of a compatible UL/
ULC listed fire alarm control unit in 4-wire or 6-wire
configurations.
Additional functions are provided to separately power the
hold open electromagnets directly from the alarm control
panel as well as connections for a remote alarm indicator
lamp.
1. Read entire instruction sheet prior to installation
and refer to NFPA 72E. Standards may be
obrained from THE NATIONAL PROTECTION
ASSOCIATION, Batterymarch Park, Quincy, MA
02269.
2. Reference unit carton for unit mounting type.
3. Prepare door and frame for fasteners using the
appropriate template. Mark, drill, and tap holes
as indicated. If surface wiring is used, omit 7/8”
hole for wire access.
NOTE: If installing the optional bypass switch, install
assembly on the end of track as shown. Fasten track to
door frame with the screw provided (T mount uses a
cylindrical spacer). Fasten the end cap assembly with
metal or wood screws provided. Connect the switch
with wire nuts and slide the cover in place. For T mount,
place end cap in extension piece and fasten to frame
with screw provided.

24V AC/DC with remote detectors: The step down transformer is not used in this connection. Perform wiring
connections as illustrated below. Additional units are wired in the same manner as unit #2. Installations using
a combination of SD-2 modules with and without remote area detectors can be wired accordingly by
substituting the wiring diagram section from unit #1, #2, or #3 in step #3 above instead of unit #1, #2, or #3
below with remote detector. The vertical dashed lines indicate where one diagram would be exchanged for
another.
NOTE: Input voltage must match detector voltage.
