SIGA-278 Double Action Fire

Alarm Station Installation Sheet

Description

The SIGA-278 Double Action Fire Alarm Station is an addressable,

normally-open, dry contact signal initiating device that requires two

user actions to initiate an alarm. First, the upper door marked LIFT

THEN PULL HANDLE must be raised to access the alarm handle.

Second, the alarm handle must be pulled to initiate an alarm. The

single input module mounted on the back of the unit supervises the

station and sends an alarm signal to the Signature controller when the

switch is closed (i.e., when the handle is pulled).

The device requires one address on the signaling line circuit (SLC).

Addresses are assigned electronically. There are no address switches.

Diagnostic LEDs provide a visible indication of the status of the module

when the unit is removed from the electrical box.

• Normal: green LED flashes

• Alarm/active: red LED flashes

Personality codes

The module requires the loop controller to download a personality

code that determines how the module operates. Table 1 shows the

personality codes available for the SIGA-278.

Code

Description

Alarm - NO latching (Class B)

Active - NO latching (Class B)

Installation

Install and wire this device in accordance with applicable national and

local codes, ordinances, and regulations.

Notes

• The device is shipped from the factory as an assembled unit; it

contains no user-serviceable parts and should not be

disassembled.

• This device will not operate without electrical power. As fires

frequently cause power interruption, we suggest that you discuss

further safeguards with your local fire protection specialist.

• Electrical supervision requires that the wire run be broken at each

terminal. Do not loop the field wires around the terminals.

To install the SIGA-278:

1. Insert the key into the cover lock and turn the key to open the

station, rotating the cover away from the backplate.

2. Verify that all field wiring is free of opens, shorts, and ground

faults.

3. Wire the module as shown in Figure 2.

4. Write the address assigned to the module on the label provided,

and apply the label to the module. Remove the serial number label

from the module, and then attach it to the project documentation.

5. Using the two #6-32 × 1/2 machine screws provided, mount the

pull station on the electrical box.

6. Install the glass rod into the mounting brackets inside the cover.

7. Set the toggle switch on the backplate to the NORMAL position.

8. Rotate the cover back into position on the backplate, turn the key

to secure the cover, and then remove the key.

The SIGA-278 Double Action Fire Alarm Station is an addressable, normally-open, dry contact signal initiating device designed to trigger a fire alarm. It requires two distinct user actions for activation: first, the upper door, marked "LIFT THEN PULL HANDLE," must be raised to access the alarm handle; second, the alarm handle must be pulled. Once the handle is pulled, the single input module located on the back of the unit supervises the station and sends an alarm signal to the Signature controller, indicating that the switch is closed.

This device requires one address on the signaling line circuit (SLC), which is assigned electronically without the need for physical address switches. Diagnostic LEDs provide visual feedback on the module's status when the unit is removed from its electrical box: a green LED flashes for normal operation, and a red LED flashes when the device is in alarm or active status.

The module's operation is determined by a personality code downloaded from the loop controller. Two personality codes are available for the SIGA-278:

Code 1: Alarm - NO latching (Class B)
Code 4: Active - NO latching (Class B)

Installation and Wiring:

Installation should adhere to applicable national and local codes, ordinances, and regulations. The device is shipped as an assembled unit and contains no user-serviceable parts, so it should not be disassembled. It requires electrical power to operate, and given that fires can cause power interruptions, users are advised to discuss further safeguards with their local fire protection specialist. Electrical supervision mandates that the wire run be broken at each terminal; looping field wires around terminals is not permitted.

To install the SIGA-278:

Insert the key into the cover lock and turn it to open the station, rotating the cover away from the backplate.
Verify that all field wiring is free of opens, shorts, and ground faults.
Wire the module according to the provided diagram.
Write the assigned address on the provided label and apply it to the module. The serial number label should be removed from the module and attached to the project documentation.
Mount the pull station on the electrical box using the two provided #6-32 x 1/2 machine screws.
Install the glass rod into the mounting brackets inside the cover.
Set the toggle switch on the backplate to the NORMAL position.
Rotate the cover back into position on the backplate, turn the key to secure the cover, and then remove the key.

Technical Specifications:

Construction: High impact plastic with a steel backplate
Compatible electrical boxes:
- North American 2-1/2 in. (64 mm) deep single-gang box
- Standard 4 in. square box 1-1/2 in. (38 mm) deep box with single-gang cover
- 276B-RSB red surface mount box
Operating environment:
- Temperature: 32 to 120°F (0 to 49°C)
- Relative humidity: 0 to 93% noncondensing
Replacement glass rods: P/N 276-GLR (package of 20 rods)

Regulatory Information:

ADA Compliance: This device meets the ADA requirements for manual pull stations.
ULC Requirements: To meet CAN/ULC-S527 ESD requirements, the device must be mounted in a grounded metal backbox.
FCC Compliance: This device complies with part 15 of the FCC Rules. Operation is subject to two conditions: (1) it may not cause harmful interference, and (2) it must accept any interference received, including interference that may cause undesired operation.

Maintenance Features:

The device includes a provision for a replacement glass rod (P/N 276-GLR, sold in packages of 20 rods), which can be installed into the mounting brackets inside the cover. This suggests that the glass rod is a consumable or replaceable component, likely designed to break upon activation to provide a clear visual indication of use and to prevent accidental re-arming without replacement.
