This system is for a ~180 child daycare, treated as an E/I-4 combination, going into a ~12,500 ft2 commercial bay in a sprinklered single story warehouse building, previously inhabited by a business occupancy, with gas service to rooftop HVAC units and the kitchen. The other tenant has a heavy-vehicle service garage, warehouse, and office space within the building, none of which requires anything beyond sprinkler monitoring and perhaps CO detection.
Life Safety
Alarm Control
The fire alarm control unit for this building is a Fire-Lite ES-200X; while it’d be possible to cram this system into an ES-50X with some work, it’d leave no room for expansion whatsoever, and a Potter panel wouldn’t save any money due to the need for DACT and Class A cards. It has one of its DACT lines connected to an HW-AV-LTE-M-2 and the other DACT line connected to a MFVN voice port from the ISP (LIne 2 on typical business gateways) with a phone line downstream of it if need be.
The panel has 18Ah batteries in it, and provides a Class A SLC with Class A auxiliary power run alongside the SLC for non-smoke life safety devices. An ANN-RLY board connects it to a nearby SAFEPATH SP40S for voice evacuation and mass notification, with a set of 12Ah batteries in that panel for standby power and a Snom PA1+ SIP paging interface permitting it to be used for regular one-way paging duties from the telephone system.
The panel is programmed with custom zone types to handle CO, fuel gas, and security monitoring – this permits CO and gas notification via the EVACS, as well as correct reporting of all conditions to the central station.
Initiation
Smoke detection in the corridors and in the staff breakroom is required by NFPA 101 and is provided by SD365T smoke detectors on the SLC; this set of 10 smoke detectors also protects the panel itself (which is located in a corridor). CO detection for the classrooms and kitchen, though, is supplied using Macurco CM-E1 conventional CO detectors on monitor modules, including a dual monitor module for the kitchen. There is also a Macurco GD-2B fuel gas detector at the kitchen, connected to the other zone of the dual monitor module there, with the detectors powered from the Class A loop.
Other dual monitor modules receive the following input pairs:
- the supervisory and waterflow switches from the sprinkler system
- the walk-in panic and failure alarms
- trouble/security alarm conditions from the access control system, as well as the office holdup switches.
There are also monitors for the kitchen hood suppression system and the voice communication system. Each of the three exits (main door, side door, and nursery) as well as the front reception desk has a BG-12LX pull station at it, and duct detection is supplied using SD365 addressable duct detectors in DNR housings at the supply and return of each AHU along with a single relay module at the AHU for shutdown. Finally, there’s a relay module at the nursery exit door to provide FA control of the delayed egress lock on that door.
The EVACS also can be directly initiated by the strobe output of a Midland WR120 weather radio in the lunchroom/storm shelter space, powered from the EVACS auxiliary power output using a Recom R78W9.0-0.5 DC/DC converter.
Notification
The notification appliances consist of:
- ELSPSTW-N speakerstrobes in all classrooms, miscellaneous rooms and corridors, set for:
- 1/4W and 15cd for regular rooms and corridors, and
- 1/2W and 30cd for the lunchroom
- ELSPKWC-N ceiling mounted speakers, set to 1/8W, to serve as infill speakers in the corridors
- ELSTW-N remote strobes in the restrooms and kitchen, with the main restrooms getting 30cd strobes and the remaining restrooms and the kitchen getting 15cd strobes
- EL4XSPSTW-N NEMA 4X speakerstrobes set for 1/4W and 15cd in the walkin cooler and walkin freezer spaces
- a pair of AtlasIED VT-157UF speakers set to 8W to provide the 99dBA needed in the kitchen
- and another pair of AtlasIED VT-157UF speakers set to 4W to provide the 85dBA minimum needed in the outdoor play area.
Exit Signage & Emergency Lighting
The exit signs in the building are CLPU2-RWRC lightbar style combination exit signs with RHLED1-PWP-MV remote heads. The exterior lighting, though, is left unchanged.
Miscellaneous Life Safety and Supervisory
The walk-ins are monitored by GRI T8800R temperature monitors powered from an AL125UL with a 7Ah battery in it. This supply also powers the LEDs on refurbished 3050CT panic switches at the walk-in entrance doors, with an EOL relay supervising that power supply, and a Seco-Larm SD-72051-V0 normally closed keyswitch for resetting the panic switches. The walk-in cooler also has a GRI 290-1 local door prop alarm on it. (There’s no need for a prop alarm on the freezer as it’s accessed from the walk-in cooler.)
There is also a Viking E-1600-20A-EWP analog emergency phone installed at the outside of the play area door and connected to FXS1 on the PBX. This permits the use of a double-cylinder deadbolt on the play area door; otherwise, it’d need a panic swinging into the building, which is an obvious security problem.
Security
The overall security system for this building is designed to meet PASS Tier I requirements, with intercom communications, monitored perimeter security & access control, doorphone visitor entry control, and perimeter video surveillance. There is also delayed-egress and glassbreak-triggered recording to protect the nursery exit door, and security film on all the glazing to provide passive resistance to breakage. Furthermore, both offices and the front desk have HUB-T holdup switches underneath the desk, connected directly to a security zone on the FACP.
Access Control
The access controlled doors have the following hardware on them:
- The main doors use Falcon MEL1692NL-OP CVR storefront exit devices with ELR
- The nursery exit uses a Falcon F-19-R-EO storefront rim exit device but with an Alarm Controls DE1200 delayed egress maglock on it
- And the side exit door has a Falcon MEL-24-R–NL rim exit device with ELR
The access controller is also tied into the existing operator for the functioning dock door.
The front and side doors also have Bas-IP AV-06M doorphones on them with SH-12 remote Wiegand converters and SH-42 remote relays tied into the main access controller. The door contacts are GRI MS20RS-Ts on all perimeter doors except for the dock door, which has Magnasphere MSS-106S-Gs on it. There are also FG-1625RT glassbreaks for the glazing in the breakroom, stub hallway, playground door, and front vestibule, while the nursery glazing is protected by FG1025Z directional glassbreaks to permit it to have 24h glassbreak protection.
The access controller itself is a CDVI ATRIUM A22K with a 20Ah battery in it for 12+ hours of standby operation (including the delayed egress maglock). This controller uses zone-doubled inputs to monitor door contacts on the perimeter doors, the doorphone remote relays for the front and side doors, the glassbreaks, and the delayed egress lock on the nursery door. The two doors are controlled by the ATRIUM’s relay outputs, and the low current outputs are used to provide door unlock inputs to the remote Wiegand interfaces as well as controlling relays that unlock the dock door, trigger the nursery camera, and provide alarm and trouble outputs to the FACP monitor module that supervises this system.
Miscellaneous Locking
The classroom doors, while not electrified, are fitted with Cal-Royal SC8071 classroom security mortise locksets. The lunchroom/storm shelter needs ICC 500 compliant hardware, though, so it uses Steelcraft Paladin PW14 doors with Ives WS45 manual holders (this works because fire doors required only for ICC 500 compliance aren’t required to self-close), Ives 5BB1HW-NRP hinges, and Von Duprin WS-T-9957-2SI panic hardware with 996L-BE trim for the three main entrance/exit doors. The kitchen door, though, isn’t an egress door for the lunchroom, so it is a Ceco/Curries StormPro door fitted with a Sargent FM7390 classroom security holdback mortise lockset and a Norton Rixson 7500 closer to permit push-pull operation under normal circumstances, along with McKinney SP3786NRP hinges.
The play area door is a new hollow metal slab with a viewing window that uses a Schlage B662 OS-LOCxIS-LOC deadbolt under 2021/2024 Code provisions that permit double-cylinder hardware to be used on doors to exterior areas that do not have egress independent of the building. The door also has an Ives 8103EZHD pull handle and a LCN 4050A-CUSH closer on it for push-pull operation when unlocked.
Video
The video system consists of a Hanwha ARN-810S PoE NVR powered from the combination of a PSA-48-120 48V DIN rail supply in a junction box and a PSH-BCM360S DC-UPS/battery charger sharing an Altronix BC1240 enclosure with a 40Ah 12V battery. The cameras consist of LND-6022R dome cameras inside the entrance doors (front, side, playground, and dock), a LNO-6012R bullet camera monitoring the outside of the side door and dock door, and an Axis M3085-V minidome with a T6101 Mk II portcast interface monitoring the nursery exit door with the portcast interface using a supervised input to receive a recording trigger from the access control system.
