EDWARDS SIGA-CR Control Relay Module Installation Guide
Description
The SIGA-CR Control Relay Module is an addressable device that provides one Form C dry contact output relay. The relay contacts transfer when the module is activated.
The module requires one address on the signaling line circuit (SLC). Addresses are assigned electronically. There are no address switches.
Diagnostic LEDs provide visible indication of the state of the module through the cover plate:
- Normal: Green LED flashes
- Alarm/active: Red LED flashes
Personality codes
Use the personality codes described below to configure the SIGA-CR module. See Table 1 for listing information.
Table 1: Personality code listing information
| Code | Description | UL 864 | CAN/ULCS527 | EN 54-18 |
|---|---|---|---|---|
| 8 | Signal – dry contact output |
Personality code 8: Signal – dry contact output. Configures the module as a dry relay contact to control external appliances (door closers, fans, dampers) or equipment shutdown.
Installation
Install this device in accordance with applicable national and local codes, ordinances, and regulations.
WARNING: Connecting a device that exceeds this module’s pilot duty contact ratings may cause activation failure. This module does not support capacitive loads. See “Specifications” on page 3 for contact ratings.
Notes
- The module is shipped from the factory as an assembled unit; it contains no user-serviceable parts and should not be disassembled.
- This module does not operate without electrical power. As fires frequently cause power interruption, discuss further safeguards with the local fire protection specialist.
- Install the module within the same room as the device it is controlling.
To install the module:
- Write the address assigned to the module on the label provided, and then apply the label to the module. Remove the serial number label from the module, and then attach it to the project documentation.
- Wire in accordance with “Wiring” on page 2.
- Using the self-tapping screw provided, attach the wall plate to the module. See Figure 1.
- Using the two machine screws provided, attach the wall plate and module to the electrical box.

Wiring
Wire this device in accordance with applicable national and local codes, ordinances, and regulations.
Notes
- Refer to the Signature loop controller installation sheet for SLC wiring specifications.
- Each terminal on the module is limited to a single conductor.
To wire the module:
- Verify that all field wiring is free of opens, shorts, and ground faults.
- Strip 1/4 in. (about 6 mm) from the ends of all wires that connect to the terminal block of the module. When stripping wire ends, exposing more wire may cause a ground fault; exposing less wire may result in a faulty connection.
- Make all wiring connections as shown in Figure 2.

Not supervised. Power-limited unless connected to a nonpower limited source. If the source is nonpower-limited, eliminate the power-limited mark and maintain a minimum of 0.25 in. (6.4 mm) space from power-limited wiring. For other mounting methods, see enclosure and bracket installation sheets to maintain separation of power-limited and nonpower-limited wiring. The wire size must be capable of handling fault current from nonpower limited source.
— or —
Use type FPL, FPLR, FPLP, or permitted substitute cables, provided these power-limited cable conductors extending beyond the jacket are separated by a minimum of 0.25 in. (6.4 mm) space or by a nonconductive sleeve or nonconductive barrier from all other conductors. Refer to the NFPA 70 National Electrical Code for more details. -
