CONNECTIONS OF INITIATING DEVICES AND
ACCESSORIES
A maximum of 4 smoke detectors may be installed with this
device. Refer to NFPA 72 and NFPA 80 for instructions
concerning proper placement and detection coverage. End-of-line
devices must be installed for supervision of electrical power to
4-wire smoke detector. When using 4-wire smoke detectors with
this device, electrical supervision must be provided by means of a
UL/ULC listed end-of-line relay.
NOTE: For low voltage wiring #18 AWG is recommended.
Normally Open “2-Wire,” Class B Style A Initiating Devices
Connect wiring from N/O initiating device loop to positions 3 and
4. Place the supervisory resistor (LMEOLRES-10) contained
within the accessory pack. (Figure 3). Observe proper polarity, 3
(+), 4 (–) when attaching to the release device’s terminal board.
NOTE: Make certain that the Wire Jumper is placed between
positions 5 and 6.
This option is a supervised, current-limited circuit.
OR
Normally Open “4-Wire,” Class B Style A Initiating Devices
Connect wiring from N/O 4-Wire initiating device loop to
positions 3 and 4, making sure an end-of-line supervisory
resistor (LMEOLRES-10) is installed as shown in Figure 4 or 5,
depending upon the type of smoke detector being used. Observe
proper polarity, 3 (+), 4 (–) when attaching to the release device’s
terminal board.
NOTE: Make certain that the Wire Jumper is placed between
positions 5 and 6.
This option is a supervised, current-limited circuit.
OR
Normally Closed “4-Wire,” Class B Style A Initiating Devices
Connect wiring from N/C 4-Wire initiating device loop to
positions 5 and 6 (Figure 6). This option is a supervised,
current-limited circuit.
NOTE: Make certain that the 10k ohm resistor is placed between
positions 3 and 4.
NOTE: End-of-line devices must be installed adjacent and after
the last initiating device. Initiating device loops are supervised
and cannot be direct series or paralleled between multiple release
devices or shared with other alarm equipment. For proper wiring
configurations from multiple smoke detectors or signaling for
simultaneous closure on multiple doors, call technical support,
1-888-528-7870. Incorrect wiring between devices may cause
damage to the release control circuit and void warranty.

W I R I N G
To prevent possible SERIOUS INJURY or DEATH:
• End-of-line devices MUST be installed for supervision of
electrical power to 4-wire smoke detector.
• DO NOT install this device on a motorized door without an
electric safety edge.
