Dorma EMR Series User manual

GENERAL DESCRIPTION
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.
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.

INSTALLATION
1. Read entire instruction sheet prior to installation
and refer to NFPA 72E. Standards may be obtained
from THE NATIONAL FIRE 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.

WIRE GAUGE: The maximum wire gauge for wiring the SD-2 detector module is #18 AWG. The method for
determining wire gauge is given below. NOTE: A minimum of 20.4 VDC must be supplied to each solenoid
in the run.
S1, S2, S3 etc. are the number of solenoids at each subsequent station. D1 is the distance from the
power supply to the first solenoid station. D2, D3, D4 etc. are the distances from the previous solenoid
station to the next solenoid station in the run. To determine the correct wire gauge multiply E1 times D1.
Add that quantity to E2 times D2. Repeat the same procedure for each electromagnet to test the last unit in
the run. Compare the quantity calculated to the chart below. The calculated value must be less than or
equal to the value corresponding to the appropriate wire gauge.
10 GAUGE-11,788 12 GAUGE-7,407 14 GAUGE-4,669 16 GAUGE-2,997 18 GAUGE-1,843
The procedure described above can be expressed in the following equation: (E1xD1) + (E2xD2) + (E3xD3)
....(EnxDn) The above values correspond to the wire gauge to be used. If the calculated value is 1,843
#18 AWG wire can be run and connected directly to the detector module. If the calculated value exceeds
1,843 larger wiring will be required. Since the detector will only accept #18 AWG wire, a wiring splice will
be necessary as illustrated below.

SD-2 DETECTOR TO AUXILIARY SOLENOID CONNECTION

SD-2 DETECTOR INTERCONNECTION
NOTE: Make this connection the same time as the main hold open solenoid
connection. Strip approximately 1/4" of plastic insulation from the ends
of the wires. Connect auxilliary hold open solenoid wires to
9&6 of SD-2 detector.
Some applications may require input power to the hold open
electromagnet to be supplied through a UL/ULC listed alarm control
panel so the hold open electromagnet functions separately from the
internal detector module. This application requires the alarm
contacts of the SD-2 detector and any remote detectors
to be connected to the alarm contacts of the control panel. An alarm indication to
the panel results in the loss of power to the hold open electromagnets in the related
zone, which allows the doors to close. Wire main electromagnet to alarm control panel as
illustrated.

enough to handle this load if the power supply is common to all units interconnected. Separate power

2a. For units without connection to remote detectors, connect terminal #15 (+) between the units to be

SD-2 DETECTOR TO REMOTE AREA DETECTOR
SD-2 DETECTOR TO AUDIBLE SIGNAL APPLIANCE
A remote open area detector can only be connected to a unit whose trouble relay contacts
(#5 & #13) are connected in a circuit for the purpose of obtaining an audible trouble signal
in the event of a circuit fault. In the event that the unit is used for releasing service only,
the trouble contacts are connected to the trouble circuit of a UL/ULC listed alarm control
panel. This condition is satisfied by the four (4) and six (6) wire supervisory connections in
the alarm initiation wiring section. Perform wiring connections as illustrated below. NOTE: The
SD-2 is wired as the E.O.L. (end of line) device for the remote detector. Therefore, it
must act as the last item in the loop.

IMPORTANT: THE UNIT MUST BE TESTED AFTER THE
INSTALLATION, BY THE END USER, TO ASSURE
THAT THE DOOR CLOSER UNITS FUNCTION PROPERLY
WHEN THE ALARM SYSTEM IS ACTIVATED. THE ENTIRE
SYSTEM MUST ALSO BE TESTED PERIODICALLY AFTER
THE INITIAL INSTALLATION TEST, IN CONJUNCTION WITH
THE TESTING OF THE FIRE ALARM SYSTEM. THE END
USER IS ALSO RESPONSIBLE FOR THE ADJUSTMENTS
AND MAINTENANCE TO RETAIN THE SYSTEM IN
WORKING ORDER.
SD-2 DETECTOR MAINTENANCE
The SD-2 Detector has been designed to be as
maintenance-free as possible. Normal air-borne
dust, however, can accumulate in the detector
sensing chamber and cause it to become more
sensitive. All detectors must be tested and cleaned
at least once a year. Detectors in dusty environ-
ments must be tested and cleaned more often.
Detectors must also be tested and cleaned imme-
diately after a fire. Failure to maintain detectors
may result in needless false alarms.

SMOKE DETECTOR TESTING
Measure and record test voltage at test points
RP1 & RP2. If the product is operating
normally, and was cleaned effectively, the test
voltage will be less than the voltage recorded
earlier. (Typical voltage for a clean device is.9
- 1.58 Vdc.)

If the detector is in an area where air velocities exceed 100 feet/minute, the detector may not
alarm on the first try. This could be due to the signal processing feature of the detector. Signal
processing is a feature that adds a time delay to each detector which effectively increases its
stability. If this is the case, spray in repeated bursts of 1 second at approximately 5 to 10 second
intervals. The total number of sprays should not exceed five (5). If the detector does not alarm
after 5 consecutive sprays, it will be necessary to generate larger volumes of smoke to overcome the
air flow dilution factor. This can be accomplished by burning paper or fabric in a metal can.
DORMA accepts the use of Home Safeguard Smoke Detector Tester (Models 1H and 25S) if, and only
if, it is used:
1. with the Model 1490 Accessory.
2. with the new formula aerosol as identified by a date code, located on the bottom
of the can, of 1990 or later. (This date code can be read as first numeral = last
digit of year so that a B0xxx = 1990 and B9xxx = 1989.)
3. in accordance with the instructions stated above.
If the preceding requirements are not met, the use of Smoke Detector Tester is unacceptable and
DORMA cannot guarantee the proper operation of detectors that have been subjected to this product.
Alternative methods of generating smoke/aerosol such as the Gemini 501 Smoke Generator Machine
may be used to cause alarm at the detector's installed location. Set the generator to represent a
4%/ft to 5%/ft obscuration as described in the Gemini 501 Manual and apply aerosol until the unit
alarms. If the Gemini unit is not available, cigarette, punk, or cotton wick are also acceptable
means of generating smoke to test this detector.
Aerosol testing is only a "go - no go" test and is not an acceptable means to determine the
smoke detector's sensitivity. See NFPA 72E.
REMEMBER:

Point the Smoke Detector Tester tube at the detector and release a burst of aerosol by depressing
the nozzle for 1 second. Give the detector sufficient time to respond. This may be up to 20
seconds.
