The Surface Mount Remote Relay Module (RRM) provides an interface between the ACU Controller and eight
Single Pole Double Throw (SPDT) and eight Double Pole Double Throw (DPDT) dry contact relays. The RRM
consists of an electronic circuit board with an on board screw terminal connectors. (The RRM with backplate only
is Product Number RRM16-E1L) The RRM can be installed in its own tampered enclosure. (The RRM with key
locked enclosure is Product Number RRM16-E00)
When attaching this device to a Summit system, please refer to the ACU3 Family Installation and Opera-
tion Guide for the list of input and output assignments.
Surface Mount (SMT) refers to a method of construction that allows the various module components to
be mounted directly on the surface of the board rather than using the traditional thru-hole method.
The RRM Each relay is rated 2 Amps at 30 VDC.
Two unsupervised inputs are available for power fault and cabinet tamper.
The Remote Relay Module requires 24 VDC (±15%).
The switches on the RRM are dynamic and can be changed while power is still applied to the board.
Changes will take effect immediately.
Auxiliary Power Supply for RRM
In many cases the ACU can supply the power for the RRM. The exception is when using an ACURS with a plugin transformer for its power supply. When the ACU cannot supply power, an auxiliary power supply must be used.
When using an auxiliary power supply make sure the 0V terminal on all remote modules and the ACU share a
common ground.
Do not use the relays on the ACU Controller, Remote Reader Electronics (RRE), Remote Input
Module (RIM) or Remote Relay Module (RRM) to switch any voltage above 30 volts. Failure to
heed this WARNING can cause death, personal injury or damage to unit(s).
RS-485 Information
RS-485 is a differential voltage communication circuit. The Impedance is 120 ohms. End-of-line terminators are
required on both ends of the communications path (See diagram below). Multi-drop configurations are allowed
with a maximum length of 4,000 feet. Stubs can be dropped, off the RS-485 cable, but the length of any stub
cannot be longer than 10 feet. Stubs can connect to ACU Controllers or remote modules (One-Stage reader,
RRE, RIM or RRM). Stubs must not be terminated. UTC Fire & Security strongly recommends star
configurations be avoided. The all remote modules have built-in terminators that are switch selectable.

RRM Field Wiring Test
After making all connections, the following tests should be made. Connections should already be completed at the ACU and the auxiliary power supply if used.
Test points and expected voltages
From To Voltage Tolerance
GND VIN + 24 VDC 3.5 VDC
T+ T- + 4.0 VDC* 0.5 VDC
R+ R- + 2.5 VDC * 0.5 VDC
+24V Bldg. Gnd. 24 VDC 3.5 VDC
GND Bldg. Gnd. 0 VDC 0.5 VDC
T+ Bldg. Gnd. Less than 6.0 VDC N/A
T- Bldg. Gnd. Less than 6.0 VDC N/A
R+ Bldg. Gnd. Less than 6.0 VDC N/A
R- Bldg. Gnd. Less than 6.0 VDC N/A
Table 12: RRM Test points and Voltages
* After the first reader is connected these voltages will modulate due to data on the line. Most Digital
Volt Meters should indicate about 2.0 VDC.
Power-Up Self-Test on the RRM
The Remote Relay Module should always be tested after installation. The indicators for the RRM are the
red LED’s located on the component board. The test should be completed in less than 10 seconds. The
LED’s will light as follows:
LED Description
A ON at power-up
B ON when successful RAM test is finished
C ON when successful PROM test and initialization completed
ON ON when Power is applied
Table 13: Power-up LED Indicators on the RRM
After all three LED’s have lit, LED B will flash at a 1 Hz rate.
