Application <br />The operating characteristics of the fire alarm stations are deter- <br />mined by their sub -type code or "Personality Code". NORMALLY - <br />OPEN ALARM - LATCHING (Pesonality Code 1) is assigned by the <br />factory; no user configuration is required. The device is configured <br />for Class B IDC operation. An ALARM signal is sent to the loop <br />controller when the station's pull lever is operated. The alarm con- <br />dition is latched at the station. <br />Compatibility <br />Signature Series manual stations are compatible only with ED- <br />WARDS's Signature Loop Controller. <br />Warnings & Cautions <br />This device will not operate without electrical power. As fires fre- <br />quently cause power interruption, we suggest you discuss further <br />safeguards with your local fire protection specialist. <br />Typical Wiring <br />The fire alarm station's terminal block accepts #18 AWG (0.75mm') <br />to #12 AWG (2.5mm') wire sizes. See Signature Loop Controller <br />catalog sheet for detailed wiring requirement spedfications. <br />Wiring Notes <br />A\ Refer to Signature Loop Controller manual for maximum <br />wire distance. <br />2. Al wiring is power limited and supervised. <br />REAR VIEW <br />of 278 <br />e O 0 <br />0 <br />TBS <br />°000 <br />Dea lm (N--D <br />(Abe/ACINe) ® ® (NomaD <br />4 °zI <br />0 1BI 0 <br />Testing & Maintenance l <br />To test (or reset) the station simply open the station and operate (( DRAIN(+): <br />the exposed switch.

The user-friendly maintenance <br />program shows the current state of each Signature series device <br />and other pertinent messages. Single devices may be deactivated <br />temporarily, from the control panel. Availability of maintenance <br />features is dependent on the fire alarm system used. <br />Scheduled maintenance (Regular or Selected) for proper system <br />operation should be planned to meet the requirements of the <br />Authority Having Jurisdiction (AHJ).
