Dealer/installer programming reference for the NAPCO GEM-P801 security control panel.
Dealer/installer programming reference for the NAPCO GEM-P801 security control panel. Use in conjunction with Installation Manual WI1089 for full definitions.
The GEM-P801 is a computerized security system panel programmed via keypad through numbered "Programming Blocks." Programming is done in Dealer Program Mode using two block types: LED Programming Blocks (press the key matching a zone/feature to toggle its LED on/off) and Direct Entry Programming Blocks (type digits directly; use G+1-6 for hex A-F).
Technical Assistance: NAPCO Toll Free Helpline (800) 645-9440.
Program zones 2 and 3 as Follower Zones (Block 02): Press C (beep), then 02 (beep). Press 2 to select zone 2. Press 3 to select zone 3. The LEDs for zones 2 and 3 light to confirm.
Set a 60-second Exit Delay (Block 10): Press C (beep), 10 (beep), then 060.
Program a hex telephone dialing prefix of "9E" (Block 44): Press C (beep), 44 (beep), then 9, then G, then 5 (G+5 = hex E).
Press C + the Block Number to view the 1st digit; press E to advance through remaining digits. Data displays in binary LED pattern per digit value 0-F. Note: In Subscriber ID Numbers, Phone Numbers, Pager Leading/Trailing digits, and Report Codes, a value entered as "0" displays as "A".
Note: Dealer Options 1 [96] and Dealer Options 2 [97] are not defaulted. If Dealer Code Lockout is enabled, the panel will not default the Dealer Code. The Event Log is erased on default.
