The SRM contains an LED indicator that will be lit when
the relay is commanded by the control panel to be in
the closed position.

Standard Relay Module (Modular Relay Card)
Standard Relay Module Wiring
The Standard Relay is a simple contact closure, breaking the
line and load wires of a normal circuit. To wire the relay into
the control circuit:
1.
Connect a 120 or 277 volt, 20 amp max, de-energized
branch circuit breaker to the relay terminal block.
2.
Connect the load wiring to the output terminal block.
N
ote:
Terminal blocks are not polarity sensitive although it
is recommended that line and load be brought into
terminal blocks in the same manner for consistency.
3.
Tighten down relay terminal screws. Manufacturer's
recommended torque rating is 7 lbs-in. (0.59 lbs-foot)
(0.8Nm).
4.
Document relay to circuit information for future
reference.
Latching Relay Module
1.
The Latching Relay Module is rated for single-pole
load use only. Connection of 2 pole circuits/loads to
the Latching Relay Module will void the equipment
warranty and may result in severe injury or death, and/
or damage to the equipment.
2.
Relay ratings are 120/ 277/347 volt, 20 amp maximum.
3.
Relay terminal blocks have a maximum limit of 6 AWG
wire.
4.
During initial power up, the relay on the Latching Relay
Module will remain in its current latched state for a
period of 30 seconds. After 30 seconds, the relay will
assume its programmed state.
5.
During a power outage, the LRM relay will remain in
the state it was in prior to the power outage. Once
power returns, the relay will stay in its state for 30
seconds then assume its programmed state.
6.
There is a manual switch on each relay that indicates
relay status and allows for a temporary override of the
lighting load. If the switch is moved towards the center

of the Modular Relay Card, the relay is ON. If the
relay switch is moved towards the outside of the relay
card, the relay is OFF . If this switch is used to override
lighting, the relay will stay in the overridden state until
the next command to that relay is given by the logic
board.

Two Pole Relay Module
1.
Two Pole Relay ratings are 208/240/480 volt, 20 amp
maximum.
2.
Relay terminal blocks have a maximum limit of 6 AWG
wire.
3.
Two Pole Relays take up two relay slots in the
enclosure.
4.
Two Pole Relays come in a Normally Open
configuration.
5.
There is an LED that will light up when the relay is
commanded to be in the closed position.
6.
To program the controller to control a Two Pole Relay
Module, apply programming to the relay number where
the relay pin connector is attached to the MRC.
