Application
The operating characteristics of the fire alarm stations are deter-
mined by their sub-type code or "Personality Code". NORMALLY-
OPEN ALARM - LATCHING (Pesonality Code 1) is assigned by the
factory; no user configuration is required. The device is configured
for Class B IDC operation. An ALARM signal is sent to the loop
controller when the station's pull lever is operated. The alarm con-
dition is latched at the station.
Compatibility
Signature Series manual stations are compatible only with ED-
WARDS's Signature Loop Controller.
Warnings & Cautions
This device will not operate without electrical power. As fires fre-
quently cause power interruption, we suggest you discuss further
safeguards with your local fire protection specialist.
Testing & Maintenance
To test (or reset) the station simply open the station and operate
the exposed switch. The SIGA-270 series are opened with a tool;
the SIGA-278 requires the key which is supplied with that station.
The station's automatic self-diagnosis identifies when it is defec-
tive and causes a trouble message. The user-friendly maintenance
program shows the current state of each Signature series device
and other pertinent messages. Single devices may be deactivated
temporarily, from the control panel. Availability of maintenance
features is dependent on the fire alarm system used.
Scheduled maintenance (Regular or Selected) for proper system
operation should be planned to meet the requirements of the
Authority Having Jurisdiction (AHJ). Refer to current NFPA 72 and
ULC CAN/ULC 536 standards.
